The reaction between zinc (Zn) and hydrogen chloride (HCl) produces zinc chloride (ZnCl), hydrogen (H2) gas, and heat. If more heat is removed from the reaction, how does the rate of reaction change to counter the action?
Zn + 2HCl ⇌ ZnCl2 + H2 + heat

The rate of the and produces more

Predict the products butane (c4h10) + oxygen —>

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
