Arsenic (III) oxide reacts with hydrochloric acid.  What is the sum of the coefficients for the reactants and products?   14 15 16 13 12

Which of the following represents the generic form of a single-displacement reaction? A) A + BX → AX + B B) AB → A + B C) AX + BY → AY + BX D) A + B → AB

FIRST, write the balanced equation that represents each reaction. THEN, classify each reaction. a) Hydrochloric acid neutralizes barium hydroxide b) Propane (C3H8) is burned. c) Chromium and oxygen form chromium (III) oxide. (Skip classifying this reaction; we will learn this reaction next week) d) Ammonium carbonate and barium chloride are mixed; barium carbonate precipitates.

Chemicals won’t react unless you have added the right ratios. If you are trying to create a product, you must add the correct amounts of reactants; otherwise it won’t form. When you balance an equation, it will inform you about how much of the reactant you need, which will enable you to guess how much product you will make. You must establish a ratio for the reaction to occur.   In your opinion, which one of these reasons is the best? Justify your response. In your opinion, which of these reasons is the worst? Justify your response. Develop a different plausible explanation and share.
