Answer:
(a) Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O. Calcium hydroxide react with nitric acid to produce calcium nitrate and water.
(b) Ethanoic acid is the systematic name for acetic acid (CH3COOH).
The formula for calcium hydroxide is Ca(OH)2 .
Balanced word equation: Two moles of ethanoic acid (acetic acid) react with one mole of calcium hydroxide to produce one mole of calcium acetate and two moles of water.
(c) How a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide.
The overall equation for this reaction is: NaOH + HCl → H2O and NaCl. Break this reaction down into two parts to see how each product forms.
(d) 2NH4OH + H2SO4----> (NH4)2SO2+ 2H2O.
