Answer:

69.647g Ag

Explanation:

First, determine the molecular weight of \(Ag_2S\):

Atomic Mass Ag = 107.87 \(\frac{g}{mol}\)

Atomic Mass S = 32.07 \(\frac{g}{mol}\)

So,

Molecular Weight \(Ag_2S\) = 2(107.87\(\frac{g}{mol}\))+(32.07\(\frac{g}{mol}\))

Molecular Weight \(Ag_2S\)=247.81\(\frac{g}{mol}\)

Then determine the mass of silver contained in the sample:

\(80.0gAg_2S(\frac{1molAg_2S}{247.81g})(\frac{2molAg}{1molAg_2S})(\frac{107.87gAg}{1molAg})=69.647gAg\)

This answer makes sense because the mass of silver in the compound must be less than the total mass of the compound.

We gain oxygen from trees through the process of photosynthesis. Photosynthesis is the biochemical process in which green plants, including trees, use sunlight, water, and carbon dioxide to produce oxygen and glucose (a form of sugar).

Trees have specialized cells called chloroplasts, which contain a pigment called chlorophyll. Chlorophyll absorbs sunlight energy.

The tree's leaves capture sunlight and use it to convert carbon dioxide (CO2) from the air and water (H2O) from the roots into glucose (C6H12O6) and oxygen (O2).

During photosynthesis, the chlorophyll in the chloroplasts helps to split water molecules into hydrogen ions (H+) and oxygen atoms (O). The oxygen atoms then combine to form O2 molecules.

The oxygen produced during photosynthesis is released into the atmosphere through tiny pores called stomata found on the surface of the tree's leaves. From there, it mixes with the surrounding air and becomes available for us to breathe.

In summary, trees produce oxygen as a byproduct of photosynthesis. They play a crucial role in maintaining the balance of oxygen and carbon dioxide in the atmosphere, providing us with the oxygen we need for respiration.

Answer:

i'm not entirely sure about the answer to this question.

Explanation:

Taking into account the definition of density, the volume of an object with a mass of 25.210 mL and a density of 11.3\(\frac{g}{cm^{3} }\)  is 2.23 cm³.

First of all, density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that relates the mass and volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

\(density=\frac{mass}{volume}\)

Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (\(\frac{kg}{m^{3} }\))or gram per cubic centimeter (\(\frac{g}{cm^{3} }\)).

In this case, you know:

Replacing in the definition of density:

\(11.3\frac{g}{cm^{3} }=\frac{25.210g}{volume}\)

Solving:

volume× 11.3 \(\frac{g}{cm^{3} }\)=25.210 g

\(volume=\frac{25.210g}{11.3\frac{g}{cm^{3} }}\)

volume= 2.23 cm³

In summary, the volume of an object with a mass of 25.210 mL and a density of 11.3\(\frac{g}{cm^{3} }\)  is 2.23 cm³.

To identify the limiting reactant, excess reactant, and theoretical yield, we first need to determine the amount of each reactant in moles.

Using the molar masses of Ca and P:

Number of moles of Ca = 17.0 g / 40.08 g/mol = 0.424 mol

Number of moles of P = 18.0 g / 30.97 g/mol = 0.581 mol

Next, we need to determine the stoichiometric ratio of the reactants. From the balanced chemical equation, we see that the ratio of Ca to P is 3:2.

3 Ca + 2 P → Ca3P2

To use the stoichiometric ratio to determine the limiting reactant, we need to compare the actual ratio of the reactants to the stoichiometric ratio.

Actual ratio of Ca to P = (0.424 mol Ca) / (0.581 mol P) ≈ 0.73

Stoichiometric ratio of Ca to P = 3/2 = 1.5

Since the actual ratio is greater than the stoichiometric ratio, Ca is the excess reactant and P is the limiting reactant.

To find the theoretical yield of Ca3P2, we need to use the stoichiometric ratio to determine how many moles of Ca3P2 can be produced from the limiting reactant (P).

From the balanced chemical equation, we see that 2 moles of P react with 3 moles of Ca to produce 1 mole of Ca3P2.

So, the number of moles of Ca3P2 that can be produced from 0.581 mol of P is:

(0.581 mol P) × (1 mol Ca3P2 / 2 mol P) = 0.2905 mol Ca3P2

Therefore, the theoretical yield of Ca3P2 is 0.2905 mol.

Answer:

\(M_{A}\) : \(M_{B}\)  = 4 : 1

Explanation:

Given that:

Volume of a cylinder = \(\pi\)\(r^{2}\)h

For cylinder A, \(l_{A}\) = \(h_{A}\) = \(\frac{1}{4} l_{B}\) and \(r_{A}\) = 4\(r_{B}\).

Volume of cylinder A = \(\pi\)\((4r_{B}) ^{2}\) × \(\frac{1}{4} l_{B}\)

                                   = 4\(\pi\)\(r_{B} ^{2}\) \(l_{B}\)

Volume of cylinder B =  \(\pi\)\((r_{B}) ^{2}\) \(l_{B}\)

                                  =  \(\pi\)\(r_{B} ^{2}\)\(l_{B}\)

To determine the ratio of their masses, density (ρ) is defined as the ratio of the mass (M) of a substance to its volume (V).

i.e    ρ = \(\frac{M}{V}\)

Thus, since the cylinders are made from the same material, they have the same density  (ρ). So that;

density of A = density of B

density of A = \(\frac{M_{A} }{4\pi r_{B} ^{2}l_{B} }\)

density of B = \(\frac{M_{B} }{\pi r_{B} ^{2}l_{B} }\)

⇒            \(\frac{M_{A} }{4\pi r_{B} ^{2}l_{B} }\)  =  \(\frac{M_{B} }{\pi r_{B} ^{2}l_{B} }\)

The ratio of mass of cylinder A to that of B is given as;

                       \(\frac{M_{A} }{M_{B} }\)  =  \(\frac{4\pi r_{B} ^{2} l_{B} }{\pi r_{B} ^{2} l_{B} }\)

⇒                        \(\frac{M_{A} }{M_{B} }\) = \(\frac{4}{1}\)

Therefore, \(M_{A}\) : \(M_{B}\)  = 4 : 1

Answer:

4.

Explanation:

Hello,

In this case, since we are talking about the same material, their densities are the same:

\(\rho _A=\rho _B\)

And each density is defined by:

\(\rho _A=\frac{m_A}{V_A} \\\\\rho _B=\frac{m_B}{V_B}\)

Thus, we also define the volume of a cylinder:

\(V_{cylinder}=\pi r^2h\)

Therefore, we obtain:

\(\rho _A=\frac{m_A}{\pi r_A^2h_A}\)

\(\rho _B=\frac{m_B}{ \pi r_B^2h_B}\)

Now, the given information regarding the the length and the radius is written mathematically:

\(h_A=\frac{1}{4} h_B\\\\r_A=4 r_B\)

So we introduce such additional equations in:

\(\frac{m_A}{\pi r_A^2h_A}=\frac{m_B}{\pi r_B^2h_B}\\\\\frac{m_A}{\pi (4r_B)^2(\frac{1}{4}h_B)}=\frac{m_B}{\pi r_B^2h_B}\\\\\frac{m_A}{m_B} =\frac{\pi (4r_B)^2(\frac{1}{4}h_B)}{\pi r_B^2h_B}\)

So we simplify for the radius and lengths:

\(\frac{m_A}{m_B} =\frac{\pi (4r_B)^2(\frac{1}{4}h_B)}{\pi r_B^2h_B}\\\\\frac{m_A}{m_B} =16 *\frac{1}{4}\\ \\\frac{m_A}{m_B} =4\)

So the ratio of the mass of cylinder A to the mass of cylinder B is 4.

A chemist decomposes 1.006 g of NaHCO₃ and obtains 0.0334 g of Na₂CO₃, The actual yield is 0.0334 g , Theoretical yield is 0.630 g , and The percent yield is 5.30 %.

The balanced equation is given as :

2NaHCO₃(s)  ------>   Na₂CO₃(S)    +    H₂O(l)   +    CO₂(g)

The actual yield or experimental yield = 0.0334 g

number of mole = mass / molar mass

mass of NaHCO₃ = 1.006 g

molar mass of NaHCO₃ = 84 g/mol

mole of NaHCO₃ =   1.006 g / 84 g/mol

                            =  0.0119  mol

it is clear, from the equation that 2 moles of NaHCO₃ produce 1 mole of  

Na₂CO₃

so, 0.0119 moles of NaHCO₃ prouduce = 1/2 × 0.0119 = 0.00595 moles of Na₂CO₃

now, moles of Na₂CO₃ = 0.00595 mol

molar mass of Na₂CO₃ = 105.9 g/mol

mass of Na₂CO₃ = 0.00595 mol ×  105.9 g/mol

                            =  0.630 g

The theoretical yield = 0.630 g

percent yield = ( actual yield / theoretical yield  ) × 100 %

        % yield  =  (0.0334 g / 0.630 g ) × 100 %

Answer: the mass of O2 present in the sample under the given conditions is 0.1495g

Explanation:

The question requires us to calculate the mass of oxygen gas (O2) that is present under the given conditions:

Volume = 120.0 mL

Pressure = 700.0 mmHg

Temperature = 15°C

To solve this problem, we can apply the equation of ideal gases, which states:

where P refers to the pressure of the system, V is the volume of gas, R is the constant of gases (R = 0.0821 L.atm/K.mol) and T is the temperature of the gas. Note that, according to the units used for the constant of gases, we need to use pressure in units of atm, V in units of liter, n is given in moles and T must be used in Kelvin.

We can rearrange the equation above to calculate the number of moles of the gas:

And, knowing that the number of moles of a susbtance corresponds to the ratio between the mass of the sample (m) and the molar mass of the compound (M), we can write:

Before applying the equation above, we need to convert the given values of pressure, volume and temperature to the appropriate units:

- Pressure:

1 atm corresponds to 760 mmHg, thus:

760 mmHg ----------- 1 atm

700.0 mmHg ------- x

Solving for x, we have that 700.0 mmHg corresponds to 0.9211 atm.

- Volume:

1 L corresponds to 100 mL, thus:

1000 mL ----------- 1 L

120.0 mL ---------- y

Solving for y, we have that 120.0 mL corresponds to 0.1200 L.

- Temperature:

0°C corresponds to 273.15 K, thus we can add 273.15 to the given temperature value to obtain the corresponding temperature:

T(K) = 15 + 273.15 = 288.15 K

Therefore, 15°C corresponds to 288.15 K.

Now that we have all values in the correct unit (P = 0.9211 atm, V = 0.1200 L and T = 288.15 K), we can apply these values to our rearranged equation to obtain the mass of O2. The molar mass of O2 is 31.998 g/mol, thus we have:

Therefore, the mass of O2 present in the sample under the given conditions is 0.1495g.

At equilibrium, the number of moles of \(Cl_2\) (g) will be 0.2025 mol.

\(C_O\)(g) + \(Cl_2\)(g) ⟶ \(C_OCl_2\)(g)

2: Set up an ICE table to track the changes in moles of the substances involved in the reaction.

Initial:

\(C_O\)(g) = 0.3500 mol

\(Cl_2\)(g) = 0.05500 mol

\(C_OCl_2\)(g) = 0 mol

Change:

\(C_O\)(g) = -x

\(Cl_2\)(g) = -x

\(C_OCl_2\)(g) = +x

Equilibrium:

\(C_O\)(g) = 0.3500 - x mol

\(Cl_2\)(g) = 0.05500 - x mol

\(C_OCl_2\)(g) = x mol

3: Write the expression for the equilibrium constant (Kc) using the concentrations of the species involved:

Kc = [\(C_OCl_2\)(g)] / [\(C_O\)(g)] * [\(Cl_2\)(g)]

4: Substitute the given equilibrium constant (Kc) value into the expression:

1.2 x \(10^3\) = x / (0.3500 - x) * (0.05500 - x)

5: Solve the equation for x. Rearrange the equation to obtain a quadratic equation:

1.2 x \(10^3\) * (0.3500 - x) * (0.05500 - x) = x

6: Simplify and solve the quadratic equation. This can be done by multiplying out the terms, rearranging the equation to standard quadratic form, and then using the quadratic formula.

7: After solving the quadratic equation, you will find two possible values for x. However, since the number of moles cannot be negative, we discard the negative solution.

8: The positive value of x represents the number of moles of \(Cl_2\)(g) at equilibrium. Substitute the value of x into the expression for \(Cl_2\)(g):

\(Cl_2\)(g) = 0.05500 - x

9: Calculate the value of \(Cl_2\)(g) at equilibrium:

\(Cl_2\)(g) = 0.05500 - x

\(Cl_2\)(g) = 0.05500 - (positive value of x)

10: Calculate the final value of \(Cl_2\) (g) at equilibrium to get the answer.
