Question 3
1 pts
Given the following Chemical equation, please determine the total number of atoms in the
highlighted product:
Al (s) + H2SO4 (aq) --> Al2(SO4)3 (aq) + H2 (g)

Highlighted- Al2(SO4)3

There will be 2 atoms of aluminum and 3 atoms of sulfate

Explanation:

The equation in this case is not balanced.  

Let us balance the equation first

The valence of aluminum is +3 and that of sulfate ion is -2

They will form bond only when there valence is equal. Thus in a compound having aluminum and sulfate, there must be 2 atoms of aluminum and 3 atoms of sulfate.

Al2(SO4)3

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

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
