Download Chemical Equation Interpretations – Match the chemical equation

Chemical Equation Interpretations – Match the chemical equation with the appropriate interpretation.
__ 1. 2CH4O(l) + O2(g)  2CH2O(l) +
2H2O(l)
__ 2. NH2Cl(g)  NH2Cl(aq)
A. The sulfuric acid dissolved in raindrops of acid rain reacts with the calcium
carbonate in seashells and marble structures. This reaction produces calcium
sulfate dissolved in water and carbon dioxide gas.
__ 3. 2C8H14(l)+23O2(g)  16CO2(g)
+ 14H2O(l)
B. To balance the effect of acid rain, solid calcium oxide has been added to
many lakes. It reacts with water to form solid calcium hydroxide, a strong base
that is only slightly soluble in water.
__ 4. H2SO4(aq) + CaCO3(s) 
CaSO4(aq) + CO2(g) + H2O(l)
C. Chloramine is added to our water supply in very small amounts to kill
bacteria.
__ 5. Hg(l) Hg(g)
D. When octane and oxygen gas are burned in our cards, carbon dioxide and
water come out in the exhaust.
__ 6. C16H30O2(s) + H2(g) 
C16H32O2(s)
__ 7. CaO(s) + H2O(l)  Ca(OH)2 (s)
E. Methanol , if ingested, reacts with oxygen to form formaldehyde, which is
toxic. Water is also formed in this reaction.
F. Liquid mercury evaporates to produce mercury vapor.
G. Saturated fatty acids, like palmitic acid, tend to form long solids and clog
people’s arteries. These saturated fatty acids can be made from unsaturated
fatty acid by adding hydrogen gas.
