2. for the following reaction, calculate how many moles of each product are formed when 0.356
moles of pbs completely react. assume there is an excess of oxygen.
2pbs(s) + 302(g) → 2pb0(s) + 2802(9)

Melting 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.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
