If the pressure of a gas sample is quadrupled and the absolute temperature is doubled, by what factor does the volume of the sam

Natasha_Volkova [10]

Answer:

D) 1/2

Explanation:

Using Ideal gas equation for same mole of gas as

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}$

Given,

P₂ = 4P₁

T₂ = 2T₁

Using above equation as:

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}$

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{4\times P_1}\times {V_2}}{2\times T_1}$

$V_2=\frac{1}{2}\times V_1$

<u>The volume change by half of the original.</u>

Sometimes you are given a measured amount of two or more reactants and asked how much product can be formed. Explain what steps

Westkost [7]

Explanation:

To solve this problem, follow these steps;

Obtain a balanced equation of the reaction and familiarize with the reactants and products.
Find the number of moles of the reacting species since they are the known matter in terms of quantity.
From the number of moles, determine the limiting reactant.
The limiting reactant is the one given in short supply.
Such reactant determines the extent of the reaction.
Compare the moles of this specie to that of the products using the balanced equation.
Obtain the mole of the desired product and find the mass or desired quantity.
simply work from the known specie to the unknown
