Answer to Question #164662 in General Chemistry for Tasneem Roberson

Question

Do not include stoichiometric coefficients in the interpretations.

Name each substance correctly (recall that rules for naming ionic and molecular substances are different).

For each substance include its state of matter (using words, not symbols). Your sentences should include verbs (remember, you are telling a story).

1. 2 Ca(NO3)2(s) ∆→ 2 CaO(s) + 4 NO2(g) + O2(g)

2. ZnCl2(aq) + 2 NaOH(aq) → Zn(OH)2(s) + 2 NaCl(aq)

3. Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g) hydrochloric acid

Answer 1

1 Solid Calcium nitrate decomposes into the following products: solid calcium oxide, nitrogen dioxide gas and oxygen gas.

2 As a result of the substitution reaction between zinc chloride solution and aquatic sodium hidroxide (caustic soda), sediment of zinc hydroxide and aquatic sodium chlorine are formed.

3 Chemical reaction between solid magnesium and hydrochloric acid solution. The result is a solution of magnesium chloride and hydrogen gas.
