for each reaction, calculate how many moles of the product
form when 0.112 mol of the reactant in color completely re-
acts. assume there is more than enough of the other reactant.
(a) 2 ca(s) + o2(g) → 2 cao(s)
(b) 4 fe(s) + 302() → 2 fe2o3(s)

Which of the following statements is true? a. elements in the last period are radioactive. b. atomic weight is the same as atomic mass. c. elements in the same group have the same number of electron shells. d. atomic number equals the number of neutrons in the nucleus of an atom.

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
