Answer:

Condensation is the process of water vapor condensing into liquid water.

Explanation:

"Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor." -National Geographic"

masha68 [24]

Answer:

A. Yes

B. –176 °C

Explanation:

A. Yes

B. Determination of the new temperature of the gas.

Let the initial pressure be P

From the question given above, the following data were obtained.

Initial pressure (P1) = P

Initial temperature (T1) = 19 °C

Final pressure (P2) = ⅓ P1 = ⅓P = P/3

Final temperature (T2) =?

Next, we shall convert 19 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 19 °C

Initial temperature (T1) = 19 °C + 273

Initial temperature (T1) = 292 K

Since the volume is constant, we can obtain the new temperature of the gas as illustrated below:

Initial pressure (P1) = P

Initial temperature (T1) = 292 K

Final pressure (P2) = P/3

Final temperature (T2) =?

P1/T1 = P2/T2

P/292 = P/3 /T2

P/292 = P/3T2

Cross multiply

P × 3T2 = 292 × P

Divide both side by P

3T2 = (292 × P)/P

3T2 = 292

Divide both side by 3

T2 = 292/3

T2 = 97.33 ≈ 97 K

Finally, we shall convert 97 K to celcius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 97

T(°C) = 97 – 273

T(°C) = –176 °C

Thus, the new temperature of the gas is –176 °C.

Match the vocabulary word with its definition. Match the items in the left column to the items in the right column. 1. The actua

tekilochka [14]

Answer:

1. The actual amount of product that is produced from a given amount of reactant or reactants. → actual yield

2. A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products. → Conservation of Mass

3. The reactant that is not used up in a reaction that goes to completion

→ excess reactant

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

6. The maximum calculated amount of product produced from a given reactant in a reaction that goes to completion. → theoretical yield

7. The study of the quantitative relationships between reactants and products in a chemical reaction. → stoichiometry

Explanation:

1. The actual amount of product that is produced from a given amount of reactant or reactants. → actual yield

The actual yield is the actual amount of product that is produced in a chemical reaction and it can be determined experimentally.

2. A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products. → Conservation of Mass

The law of conservation of mass states that mass in an isolated closed system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

3. The reactant that is not used up in a reaction that goes to completion

→ excess reactant

In any chemical reaction between two or more reactants, the excess reactant is the substance that is leftover when the chemical reaction is ended. The amount of product formed is not limited by this reagent.

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant

In any chemical reaction between two or more reactants, the limiting reactant is the substance that is consumed completely when the chemical reaction is ended. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

percent yield = (actual yield / theoretical yield) *100

6. The maximum calculated amount of product produced from a given

reactant in a reaction that goes to completion.

→ theoretical yield

theoretical yield is defined as the amount of the obtained desired product.

7. The study of the quantitative relationships between reactants and products in a chemical reaction.

→ Stoichiometry

Stoichiometry is a branch of chemistry that deals with relationships between reactants and/or products in a reaction to determine desired quantitative data.
