Question
2. Answer the following problems with complete solutions.
Problem #4: Interpret reactions in terms of representative particles, then write
balanced chemical equations and compare with your results. Determine limiting and
excess reagent and the amount of unreacted excess reactant.
a) 3 atoms of carbon combine with 4 molecules of hydrogen to produce methane
(CH.)
b) 7 molecules of hydrogen and 2 molecules of nitrogen gases react to produce
ammonia
c) 4 molecules of hydrogen and 5 molecules of chlorine react.
Problem #5: Suppose 316.0 g aluminum sulfide reacts with 493.0 g of water. What
mass of the excess reactant remains?
The unbalanced equation is:
Al,S; + H,O ---> Al(OH); + H,S
Problem #6: In this reaction:
CACO3 + 2HCI ---> CaCl, + CO, + H,O
6.088 g CACO; reacted with 2.852 g HCl. What mass of CaCO3 remains unreacted?
