(a) The heat of reactionfor the combustion of C₂H₄ is 1411 kJ/mol. Write a balancedthermochemical equation for the combustion of C₂H₄. (b) Howmany grams of C₂H₄ must burn to give 70.0 kJ of heat?
The reaction of solid calcium fluoride and sulfuric acid produces calcium sulfate solids and gaseous HF. The gas product is dissolved in water to form hydrofluoric acid. Fluorite ore, a source of calcium fluoride, contains 95%wt CaF2 and 5%wt SiO2. In a certain process, the ore is reacted with 93%wt aqueous sulfuric acid, supplied 15% in excess. From this, 95% of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction: HF reacts with SiO2 to produce H2SiF6 and liquid water. If 60%wt of hydrofluoric acid was formed when hydrogen fluoride (which exits the reactor) is dissolved in water, determine the amount of ore needed to produce one metric ton of acid. Report your answers to one decimal place only.

1. One of the first families of rockets used by the American space program was the Redstonefamily of rockets. The first Redstone rockets (in the 1950s) used B10H14 (often called decaborane)as a rocket fuel that reacts violently with liquid di-oxygen to make diboron trioxide and steam.When used as a rocket fuel, scientists carefully calculated the amount necessary so that bothcomponents ran out at the same time. (Excess fuel would be excess weight for the rocket tocarry.) If the total mass of both reactants put together is 12.0  104 kg, what was the volume ofliquid di-oxygen carried by the rockets? (Liquid di-oxygen has a density of 1.141 g/mL.)
