What is the complete balanced equation for the reaction between magnesium hydroxide and hydrogen chloride to
produce magnesium chloride and water is
O MgOH + HCI → MgCl + H2O.
O Mg(OH)2 + 2HCl → MgCl2 + 2H20.
O Mg(OH)2 + HCl → Mg + 2CO2 +3H20.
O Mg(OH)2 + 2HCl → MgCl2 + H2 + O2.

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Can someone me with questions 12 and 13 plz.

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams
