How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 0.98 atm and a temperature of 373 K?

Answers

Answer:

There are 1, 13 moles of chlorine gas.

Explanation:

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:

PV= nRT ---> n= PV/RT

n= 0,98 atm x 35,5 L /0,082 l atm / K mol x 373 K

n= 1,137448506 mol

In an exothermic energy diagram, the reactants side is higher in energy than the product side.

What is an exothermic reaction?

An exothermic reaction is one in which the heat of the reactants is greater than that of the products. In that case, energy is given off in the reaction as heat and the reaction vessel is warmer.

Now, in an exothermic energy diagram, the reactants side is higher in energy than the product side.
