Question

23. What are the correct formulas and coefficients for the products of the following double replacement reaction? Al(OH)3 + H3PO4 → *
a. AlPO4 + H2O

b. AlPO4 + 3 H2O

c. H3Al + (OH)3PO4

d. 3AlPO4 + H3(OH)3

24. What type of reaction is 2S(s) + 3O2 (g) → 2SO3(g)? *

a. combination reaction

b. decomposition reaction

c. single replacement reaction

d. double replacement reaction

Answer 1

23. The correct answer would be a (AlPO4 + H2O).

This is an example of a neutralization reaction (an acid and a base react to form water and a salt).

24. a, combination reaction. There are two reactants and one product.
