Suppose you are performing a gas-producing reaction to experimentally determine the molar volume of the gas. Mg (s) + 2 HC1 (aq) →→→MgCl₂ (aq) + H₂ (g) A sample of Mg produces 21.5 mL of H₂ gas. The gas is collected over water at an atmospheric pressure of 769.6 mm Hg at 22 °C, at which the vapor pressure of water is 19.8 mm Hg. What is the experimental value for the molar volume of the hydrogen gas in L/mol?

Write a balanced chemical equation for the standard formation reaction of solid water H2O

The following reaction represents the process known as photosynthesis: 6CO₂(g) + 6H₂O(l) + sunlight → C₆H₁₂O₆(aq) + 6O₂(g). Is photosynthesis a redox reaction? Justify your answer using redox principles.

The manufacture of nitrogen trifluoride is a growing industry, due to its use as a plasma etchant in the semiconductor industry. Nitrogen trifluoride can be synthesized by passing a current through a high-temperature mixture of ammonium fluoride and hydrogen fluoride, with hydrogen gas as a byproduct. In one synthesis, 1.20x10^3g ammonium fluoride is reacted with1.20x10^3g hydrogen fluoride to produce 5.00x10^2g nitrogen trifluoride. What is the limiting reactant, excess reactant, theoretical yield of nitrogen trifluoride, percent yield, and mass of excess reactant remaining after the reaction?
