Identify the oxidising and reducing agents in these reactions, by looking at the gaming and loss of ovygen. a) 2Mg + O2 = 2MgO

B) Fe2O3 + 3CO = 2Fe + 3CO2

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?

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.
