Given the balanced equation, 2H2(g) + O2(g) → 2H2O(g), what is the total mass of hydrogen gas that reacts completely with 32 g of oxygen gas to produce 36 g of water vapor. Hint: use the Law of Conservation of Mass. YOU MUST SHOW WORK.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. polyethylene is a plastic material called thermoplastic. one very useful property of thermoplastic is that when it is heated it turns into liquid, which can be molded into desired shape and size. also the material do not dissolve at room temperature.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.

When china's civil war resumed, the nationalists held an advantage because the nationalist had more soldiers  than the communist.
