Answer:

D) Chlorine, Cl

Answer:

- Daniel- Earth and Space

- Sanya- Chemistry

Explanation:

Daniel's study field is associated with the 'Earth and Space' as he is attempting to explore how the frequency of tropical storms(in the atmosphere) and coastal erosion(relation with land and ocean) are interconnected to each other. He studies how the two are associated and affect life on the planet.

While Sanya's field of study would be 'Chemistry' as she aims to study the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules('whether the discharge from industrial plants has any impact on the pH concentration of freshwater swamps in the surrounding area').

Answer:

Given - acc = 4 m/ s^2

Force = 255 N

To find = mass

Solution -

Using the formula,

\(f = m \times a\)

255 = Mass × 4

255 /4 = Mass

63.75 = Mass

1 N = kg m/s^2

63.75 kg = Mass

Answer:

c = 0.79 j/g.K

c = 1 j/g.K

T2 = 123.1 K

Explanation:

1)

Given data:

Mass of metal = 450 g

Heat loses = 34,500 j

Temperature drop = ΔT  = 97 K

Specific heat of metal = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

34500 j = 450 g ×c × 97 K

34500 j = 43650 g.K ×c

c = 34500 j/43650 g.K

c = 0.79 j/g.K

2)

Given data:

Mass of metal = 25 g

Heat loses = 2600 j

Temperature drop = ΔT  = 103 K

Specific heat of metal = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

2600 j = 25 g ×c × 103 K

2600  j = 2575 g.K ×c

c = 2600 j/2575 g.K

c = 1 j/g.K

3)

Given data:

Mass of water = 10 g

Heat absorbed  = 840 j

Initial temperature drop = 298 K

Final temperature = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

840 j = 10 g ×4.18 j/g.K × [T2 - 103 K]

840 j = 41.8 J/K ×  [T2 - 103 K]

840 J/41.8 J/ K = T2 - 103 K

20.1 k = T2 - 103 K

T2 = 20.1 K + 103 K

T2 = 123.1 K

The new volume of the gas in the balloon when the pressure is doubled is determined as 11.2 L.

The new volume of the balloon is determined by applying general gas equation as shown below

P₁V₁/T₁ = P₂V₂/T₂

Where;

\(\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \\\\V_2 = \frac{P_1V_1T_2}{T_1P_2} \\\\V_2 = \frac{1 \times 22.4 \times 273}{273 \times 2} \\\\V_2 = 11.2 \ L\)

Thus, the new volume of the gas in the balloon when the pressure is doubled is determined as 11.2 L.

Answer:

The answer is D

Answer:

THE 1st one

Explanation:

Answer:

frick u beotch

Explanation:

The new volume of the gas, assuming constant temperature and a change in pressure from 760 torr to 730 torr, is 2.09 L.

Using the Boyle's Law equation,

P₁V₁ = P₂V₂,

where P is pressure and V is volume, we can solve for V₂ by plugging in the given values in the equation:

(760 torr)(2.00 L) = (730 torr)(V₂)

Solving for V₂, we get:

V₂ = (760 torr)(2.00 L) / (730 torr) = 2.09 L

Therefore, the new volume of the gas is 2.09 L.

This result makes sense because according to Boyle's Law, as pressure decreases, volume increases proportionally, assuming a constant temperature.

Answer: All the answers are given below.

Explanation:

The vapor pressure of water at 75°C is approximately 293 mmHg (whole number).

The vapor pressure of bromine at 300 K is approximately 240 mmHg (whole number).

The boiling point of mercury is 357°C at atmospheric pressure (760 mmHg), and the vapor pressure of mercury is 500 mmHg at a higher temperature than this. Therefore, the temperature at which the vapor pressure of mercury is 500 mmHg is greater than 357°C.

Diethyl ether's normal boiling point is 34.6°C, which is above the freezing temperature of water (0°C). At 0°C, the vapor pressure of diethyl ether is approximately 5.5 mmHg (whole number).

At a pressure of 50 mmHg, ethanol will boil at approximately 64°C (whole number).

The normal boiling point pressure for water is 101.3 kPa (exact number) at a temperature of 100°C.

The normal boiling point pressure for water is 760 mmHg (exact number) at a temperature of 100°C.

The normal boiling point temperature in Celsius of n-Octane is approximately 126°C (whole number).

The normal boiling point temperature in Kelvin of ethylene glycol is approximately 471 K (whole number).

To find the boiling point of ethylene glycol at a pressure of 0.20 atm, you can use the Clausius-Clapeyron equation. However, the equation requires knowing the vapor pressure of ethylene glycol at a known temperature. Without this information, it is not possible to calculate the boiling point.

In the given reaction, aluminum (Al) was oxidized.

Oxidation is the loss of electrons, and reduction is the gain of electrons. In this reaction, aluminum (Al) goes from an oxidation state of 0 to +3, which means it loses three electrons. Therefore, aluminum is oxidized.

On the other hand, copper (\(Cu^{2+}\)) goes from an oxidation state of +2 to 0, which means it gains two electrons. Therefore, copper is reduced.

Remember, oxidation and reduction always occur simultaneously in a redox reaction. The species that loses electrons is oxidized, while the species that gains electrons is reduced.

The two products of this neutralization reaction are water (H2O) and rubidium chloride (RbCl).

To determine which substance acts as an acid and which substance acts as a base in the forward direction of the given reaction (H2S + H2O ⇌ H3O+ + HS-), we can consider the concept of proton transfer. Acids are substances that can donate protons (H+ ions), while bases are substances that can accept protons.

In this reaction, H2S can donate a proton, making it an acid. It transfers a proton to H2O, which can accept the proton, making it a base. The resulting H3O+ (hydronium ion) is formed by the addition of the proton to H2O, and the HS- (hydrogen sulfide ion) is formed by the loss of the proton from H2S.

The neutralization reaction between HCl (hydrochloric acid) and RbOH (rubidium hydroxide) will produce two products: water (H2O) and a salt. The acid (HCl) donates a proton to the base (RbOH), resulting in the formation of water. The remaining components, Rb+ and Cl-, combine to form the salt (rubidium chloride).
