For the given chemical equation, write the necessary stoichiometric coefficients to balance the equation. Note that normally we wouldn't write a coefficient of one, however you must include a coefficient of one if appropriate to not lose points. Al(s) + H2SO4(aq) → Al2(SO4)3(aq) + H2(g)
Nitroglycerin, a very unstable compound (molecular structure shown below), is a liquid at room temperature. When heated to 218.0°C or subjected to shock, it rapidly decomposes into four different gases. Liquid nitroglycerin has a density of approximately 1.60 g/mL. The nitroglycerin decomposition reaction equation is: 4 C3H5N3O9 (1)→ 12 CO₂(g) + 10 H₂O(g) + 6 N₂(g) + O₂(g) Assume that when heated to 218.0°C, 1.00 lb of nitroglycerin explodes heating the product gases to 750.0°C.
