What type of compound is cuso4?

a.) monotomic ionic

b.) polyatomic covalent

c.) polyatomic ionic

d.) binary molecular

Polyatomic ionic

Explanation:

A compound is polyatomic if it has more than one atoms.

Here the given compound has one copper, one sulfur and four oxygen atoms so it is polyatomic.

The other feature of the compound is presence of ionic bond (the bond formed by complete transfer of electrons / acceptance of electrons).

Here the compound will dissociate into copper ions and sulfate ion

Hence we can define it as polyatomic ionic compound.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

fe 55.85 g/mol and h2o 18.02 g/mol.
