The action that would most likely lead to. Decrease in volume is decrease in temperature.

<u>Answer:</u> The correct answer is decreasing temperature.

<u>Explanation:</u>

The relation between pressure, temperature, volume and number of moles of gas is given by the equal known as ideal gas equation:

PV=nRT

or,

P=\frac{nRT}{V}

where,

P = Pressure of the gas

V = Volume of the gas

n = Number of moles of gas

R = Gas constant

T = Temperature of gas

From the above relation, it is visible that pressure is directly related to number of moles and temperature of the gas. So, if pressure decreases, the number of moles and temperature of the gas also decreases.

Also, pressure is inversely related to volume of the gas. So, if pressure gets decreased, the volume of the gas must increase.

And, pressure is directly related to number of collisions of the particles. Thus, if the pressure decreases, this means that number of collisions between the particles must also decrease.

Hence, the correct answer is decreasing temperature.

What is the maximum amount of CO2
Wittaler [7]

Answer:

10.6 g CO₂

Explanation:

You have not been given a limiting reagent. Therefore, to find the maximum amount of CO₂, you need to convert the masses of both reactants to CO₂. The smaller amount of CO₂ produced will be the accurate amount. This is because that amount is all the corresponding reactant can produce before it runs out.

To find the mass of CO₂, you need to (1) convert grams C₂H₂/O₂ to moles (via molar mass), then (2) convert moles C₂H₂/O₂ to moles CO₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles CO₂ to grams (via molar mass). *I had to guess the chemical reaction because the reaction coefficients are necessary in calculating the mass of CO₂.*

C₂H₂ + O₂ ----> 2 CO₂ + H₂

9.31 g C₂H₂            1 mole               2 moles CO₂          44.0095 g
------------------  x  -------------------  x  ----------------------  x  -------------------  =
                            26.0373 g           1 mole C₂H₂              1 mole

=  31.5 g CO₂

3.8 g O₂             1 mole               2 moles CO₂          44.0095 g
-------------  x  --------------------  x  ----------------------  x  --------------------  =
                       31.9988 g              1 mole O₂                 1 mole

=  10.6 g CO₂

10.6 g CO₂ is the maximum amount of CO₂ that can be produced. In other words, the entire 3.8 g O₂ will be used up in the reaction before all of the 9.31 g C₂H₂ will be used.
