6) How should the conditions be changed to prevent the volume of a given mass of gas from expanding when its mass is increased
JulijaS [17]

Answer: increase pressure and decrease temperature.

Explanation:

Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)

How many molecules of iodine are produced when 9.3×1026 molecules of chlorine gas react with lithium iodide?
Bas_tet [7]

Answer:

9.3x10^{26}molec\ I_2

Explanation:

Hello!

In this case, considering the balanced chemical reaction:

Cl₂ + 2LiI ⇒ 2LiCl + I₂

We can see there is a 1:1 mole ratio between the produced iodine and the used chlorine, thus, we infer that the number of molecules of iodine given those of chlorine turn out:

9.3x10^{26}molec\ Cl_2*\frac{6.022x10^{23}molec\ I_2}{6.022x10^{23}molec\ Cl_2} =9.3x10^{26}molec\ I_2

Best regards!
