Hydrogen gas and oxygen gas is combined in a synthesis reaction in activity 3 when we tested for the gas produced in the single displacement reaction. Answer the following question about the reaction: 1. For the synthesis reaction, complete the reaction below by reaction below by writing the coefficients of the reactants and product(s) of the reaction. From left to right: • In the first, second and third boxes put the numerical value to balance the equation (ex, 1, 2, 3, 4, etc.) • In the fourth box put the formula of the product (ex, H2O or NH3) • In the fifth box, put the state of the product (ex, solid (s), liquid (l), gas (g), or aqueous (aq))

The interest rate quoted by a bank is 5.00% APR, compounded semi-annually. You decide to invest $10,000 (today, now) with this bank. Part A. What is the future value of your investment in 5 years, assuming that the interest rate will not change for the five years? Part B. Assume the interest rate (APR) itself will be increasing by 2% per year. What is the future value of your investment in ten years? (E.g. In year #2 the interest rate is 5.00% x 1.02 = 5.1%.)
