Write and balance chemical equations: 1. Aqueous ammonium chloride reacts with aqueous sodium hydroxide to form ammonia gas, liquid water, and aqueous sodium chloride. 2. Aqueous sodium phosphate and liquid water are formed when aqueous sodium hydroxide reacts with phosphoric acid. 3. 6. magnesium hydroxide + ammonium phosphate → magnesium phosphate + ammonia + water. 7. iron(III)bromide + ammonium sulfide → iron(III)sulfide + ammonium bromide. 8. calcium oxide + diphosphorus pentoxide → calcium phosphate. 9. sodium carbonate + sulfuric acid → sodium sulfate + carbon dioxide + water. 10.

Please change the following word equations into formula equations and balance them. 1. solid copper plus solid sulfur makes solid copper (I) sulfide. 2Cu(s) + S(s) (Cu2S(s) 2. phosphoric acid plus calcium hydroxide makes solid calcium phosphate plus water . 2H3PO4(aq) + 3Ca(OH)2 (aq)(Ca3(PO4)2(s) + 6H2O(l) We have a metal (Calcium) and then a polyatomic ion (when you see a name ending in ate it is likely an ion). That means it's a ternary ionic compound. Write the element symbol and ionic charge for Calcium. Look up the name and charge for phosphate ion on the Common Ion Table; Balance the charges so the total charge on the compound is zero.

Calcium phosphate aggregates form in soln. with compns. and Ca coordination that are similar to those found in Posner's cluster, but the stoichiometry of these species is dependent on the ionic compn. of the soln.: calcium-deficient clusters in solns. with low Ca : P ratio; cluster contg. protonated phosphate groups in neutral solns.; sodium ... 2+(NO. 3 -) 2. or Mg(NO. 3 -) 2. Rule 2: Brackets() are needed when apolyatomic group > 1 in a compound. Poly = ‘many’ The hydroxide ion, formula OH-, is a polyatomic group since it is made up of two different elements. Eg.
