Answer 2

I will try to answer your question in detail. Here are the possible chemical reactions, their types, and their products:

a) Sulfuric acid + aluminum hydroxide =

This is a neutralization reaction, where an acid and a base react to form a salt and water. The products are aluminum sulfate and water. The balanced equation is:

2H2SO4 + Al(OH)3 = Al2(SO4)3 + 3H2O

b) Calcium oxide + water =

This is a combination reaction, where two or more substances combine to form a single product. The product is calcium hydroxide, which is a base. The balanced equation is:

CaO + H2O = Ca(OH)2

c) Copper + hydrochloric acid =

This is a single displacement reaction, where a metal displaces a hydrogen atom from an acid. The products are copper chloride and hydrogen gas. However, this reaction only occurs if the acid is concentrated and the copper is in the form of powder or thin foil. Otherwise, copper does not react with hydrochloric acid because it is less reactive than hydrogen. The balanced equation is:

Cu + 2HCl = CuCl2 + H2

d) Iron (III) oxide + hydrogen =

This is a redox reaction, where oxidation and reduction occur simultaneously. Oxidation is the loss of electrons, and reduction is the gain of electrons. In this reaction, iron (III) oxide is reduced to iron, and hydrogen is oxidized to water. The products are iron and water. The balanced equation is:

Fe2O3 + 3H2 = 2Fe + 3H2O

e) Nitric acid =

This is not a complete question, because there is no second reactant or product given. Nitric acid can undergo different types of reactions depending on what it reacts with. For example, it can react with metals, bases, carbonates, or other acids. Some possible reactions are:

- Nitric acid + sodium hydroxide = sodium nitrate + water (neutralization reaction) - Nitric acid + zinc = zinc nitrate + hydrogen gas (single displacement reaction) - Nitric acid + sodium carbonate = sodium nitrate + carbon dioxide + water (double displacement reaction) - Nitric acid + sulfuric acid = nitronium ion + hydrogen sulfate ion (acid-base reaction)
