After mowing the lawn on a hot, hazy, humid day, you get a large glass from the kitchen and fill it with ice and water. Immediately, drops of liquid water form on the outside of the glass. The change in state of water that you are observing on your glass is condensation.

When hot and humid air comes into contact with a cold surface, such as the outside of a glass filled with cold water and ice, the water vapor in the air condenses into liquid droplets on the surface of the glass. This is what causes the drops of water to form on the outside of the glass. The change in state of water that you are observing on your glass is condensation.

Scientific notation shortens large numbers. The number right after the decimal point can only be between 1 and 9, which you did correctly. When converting to scientific notation, the exponent of ten is based on how many places you moved the decimal and the direction you moved it (left, positive; right, negative). In this case, the exponent of ten is a positive seven.

The pH value of this buffer is 4.04.

A mixture of a weak acid and its conjugated base (here: benzoic acid and sodium benzoate) or a weak base and its conjugated acid is called a buffer. When calculating the pH value of a buffer, we use the Henderson-Hasselbalch equation:

\(pH = pKa+log\frac{[base]}{[acid]}\)

pKa - negative logarithm of acid's acidity constant (for benzoic acid, pKa = 4.19)

[base] - molarity of the basic component (sodium benzoate, NaOBz)

[acid] - molarity of the acidic component (benzoic acid, BzOH)

To calculate pH, we need the molarities of both sodium benzoate and benzoic acid. However, because the volume values for both components are the same, we can actually just use their number of moles (n). We can calculate the number of moles of each component using their mass (m) and molar mass (M):

n = m/M

n(NaOBz) = m(NaOBz) / M(NaOBz)

n(NaOBz) = 2.05 g / 144.11 g/mol

n(NaOBz) = 0.0142 mol

n(BzOH) = m(BzOH) / M(BzOH)

n(BzOH) = 2.47 g / 122.12 g/mol

n(NaOBz) = 0.0202 mol

Now we can plug these values into the equation:

pH = 4.19 + log(0.0142/0.0202)

pH = 4.19 + log(0.703)

pH = 4.19 - 0.15

pH = 4.04

The molecules of Fe formed are 3.37 x 10²⁴ atoms, this can be calculated in the below section.

The reaction is this one:

Fe + CuSO₄ --> Cu + FeSO₄

The reaction mentioned above is the displacement reaction, here the ion of one of the reactant is displaced from the other compound and results into a product and displaces the other metal.

And the ratio for the reaction is 1:1

If 5.6 moles of iron react, you will have 5.6 moles of FeSO₄. By the way, you should use NA (Avogadro number) to calculate the number of molecules.

1 mol = 6.02x10²³

Therefore,

5.6 moles = (5.6 x 6.02x10²³) = 3.37 x 10²⁴ atoms

Therefore, the molecules of Fe formed are 3.37 x 10²⁴ atoms.

Coupled reactions (B) is the proper response. Coupled reactions are defined as two processes that occur simultaneously, one releasing energy and the other requiring energy.

One reaction generates energy that powers the subsequent one. In this instance, the active transport of calcium across a membrane necessitates energy, which is released when a phosphoanhydride bond on ATP is broken. Because endergonic processes need energy input, option (A) is erroneous. In this instance, calcium transport rather than the pair of processes is endergonic. Exergonic processes release energy, hence, option (C) is erroneous. Although the two reactions are not exergonic, breaking a bond is.

Answer:4

Answer:

177.1 L

Explanation:

The excersise can be solved, by the Ideal Gases Law.

P . V = n . R . T

In first step we need to determine the moles of gas:

We convert T° from, C° to K → 20°C + 273 = 293K

We convert P from mmHg to atm → 760 mmHg = 1atm

1Dm³ = 1L → 190L

We replace: 190 L . 1 atm = n . 0.082 . 293K

(190L.atm) / 0.082 . 293K = 7.91 moles.

We replace equation at STP conditions (1 atm and 273K)

V = (n . R .T) / P

V = (7.91 mol . 0.082 . 273K) / 1atm = 177.1 L

We can also make a rule of three:

At STP conditions 1 mol of gas occupies 22.4L

Then, 7.91 moles will be contained at (7.91 . 22.4) /1 = 177.1L

C) no energy is lost; the total amount of energy remains the same.

Explanation

The law of conservation of energy states that "The energy can neither be created nor destroyed - only converted from one form of energy to another." Therefore some energy will be used for metabolism while the other can be used for other properties and some can be stored.

The enthalpy of the reaction as seen from the calculations is - 137.2 kJ/mol.

To determine the enthalpy change of a reaction, we need to know the difference between the enthalpy of the products and the enthalpy of the reactants. This difference is known as the enthalpy change or the heat of reaction.

The enthalpy change of a reaction can be calculated using the following formula:

ΔH = ΣnΔHf(products) - ΣmΔHf(reactants)

where ΔH is the enthalpy change of the reaction, n and m are the stoichiometric coefficients of the products and reactants, respectively, and ΔHf is the standard enthalpy of formation of the species.

Enthalpy of reaction = Enthalpy of products - Enthalpy of reactants

(-84.7) -(52.5 + 0)

=> The colour of this stone is usually a pale greenish blue, owing to the presence of iron impurities. Stones that are treated with heat look more blue than green. On the Mohs scale of hardness, aquamarine ranges between 7.5 and 8 making it a relatively hard gemstone.

=> The best way to identify a real aquamarine stone is by looking at its colour. In its natural form, they have a pale blue colour, which is similar to seawater. They may have a slight green or yellow tint as well. Naturally occurring gems have excellent clarity and transparency.

=> The hardness of the stone is another feature you can use to identify the stone. Aquamarine stones are hard and they don’t get scratches easily. However, they can easily scratch glass and other such surfaces. So, if you find visible scratches on the stone, rethink your decision to buy it.

=> Most faceted aquamarine stones are clean to the eye and clear of any inclusions. However, translucent and opaque aquamarine is also available. These are usually fashioned into cabochons or beads. In some cases, inclusions may appear as parallel tubes. Such stones can be crafted to show a cat’s eye. Stones with cat’s eye and star effect are rare and highly priced.

A substance composed of atoms of more than one element that are held together by chemical bonds is called a compound. Therefore the correct option is option A.

A compound is a pure material that is created by chemically combining two or more distinct components in a specific order. Chemical bonds, which can be ionic or covalent, hold the atoms of a substance together.

The characteristics of compounds are distinct from the characteristics of the constituent parts.

For instance, sodium is a soft metal and chlorine is a greenish-yellow gas; nevertheless, when these two elements combine to produce sodium chloride (table salt), they create a white crystalline solid that is far more stable than the constituent parts of each element alone. Therefore the correct option is option A.

The pH that an acid will produce in solution will decrease the stronger the acid is. The negative logarithm of the concentration of hydronium ions is used to calculate pH.

An acid's relative strength can be anticipated based on its chemical composition. An acid is often more powerful when the H-A bond is more polar. Additionally, acidity increases with weaker H-A bonds and more stable conjugate bases like A.

Strong electrical conductivity indicates that an acid or base is a strong acid or base. A weak acid or base is one that conducts electricity only slightly. Demonstration of Acid and Base Conductivity: Using a light bulb equipment, the instructor will measure the conductivity of several solutions.

Answer:

A. In a graduated cylinder, put some quantity of water and measure the initial volume. Then put a coin and measure the volume. To find the volume of the coin, simply subtract the initial volume (water only) from the ending volume (water + coin). To measure the mass, take a dry coin and place it on an electronic scale. Density = mass / volume, so divide the mass by the volume to calculate the density of the coin.

B. When measuring the volume, make sure to look at the graduated cylinder at eye level and read from the bottom of the meniscus.
