Consider a hypothetical reaction in which A and B are reactants and C and D are products. If 15 g of A completely reacts with 26 g of B to produce 19 g of C, how many grams of D will be produced?

Label a-f based on the table using c for concentrated and d for dilute

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
