A chemical reaction between 6.0 g of substance A and 8.0 g of substance B, yields exactly 14.0 g of product C. In an experiment, a student added 4.0 g of A and reacted it with 4.0 g of B. This resulted in the formation of exactly 7.0 g of C. Assuming that the student performed the reaction in a closed system, which of the following statements is FALSE about the student's experiment? Select one: O a. There is an amount of a reactant that remains unchanged after the reaction. O b. The reactants were completely used up to produce 7.0 g of C. O c. The total mass of the system after the reaction is 8.0 g. Od. The chemical composition of the product remains constant in this experiment.

Soda ash (sodium carbonate) is widely used in the manufacture of glass. Prior to the environmental movement much of it was produced by the following reaction. CaCO3 + 2 NaCl → Na2CO3 + CaCl2 Unfortunately, the byproduct calcium chloride is of little use and was dumped into rivers, creating a pollution problem. As a result of the environmental movement, all of these plants closed. Assume that 125g of calcium carbonate (100.09 g/mol) and 125 g of sodium chloride (58.44 g/mol) are allowed to react. Determine how many grams of useful sodium carbonate (105.99 g/mol) will be produced. How many grams of useless calcium chloride (110.98 g/mol) will be produced? You should also determine how many grams of excess reactants are left (indicate which one is the limiting reactant)

Hydrogen is manufactured on an industrial scale by this sequence of reactions: CH4 (g) + H₂O(g) = CO (g) + 3H₂(g) CO(g) + H₂O(g) = CO₂ (g) + H₂(g) The net reaction is: CH4 (g) + 2 H₂O(g) = CO₂(g) + 4H₂(g) Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K₁ and K₂. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator. K = 0 ロ・ロ X K₁ K₂ 4 K
