b.
single-replacement
c.
synthesis
d.
neutralization double-replacement
e.

Reaction 1 is a synthesis type of reactant because it involves combination of two elements. Reaction 2 is a decomposition type since it breaks down the original compound to more than 1 compounds or elements. Reaction 3 is a single replacement reaction. Reaction 4 is a combustion type since it uses oxygen. Reaction 4 is a neutralization double-displacement since it exchanges the places of cations at the same time it produces water. Reaction 5 is a precipitation double-replacement since it also exchanges the places of cations at the same time produces a solid product.Answers are C, A, B, E, D, and F in order.

Gallium melts near room temperature and has one of the largest  liquid  ranges of any metal, so it has found use in high temperature thermometers.
