Answer:
The density is 7 g/cm^3
Explanation:
The formula for density is p=m/V. Where p is the density, m is mass, and V is the volume. 14/2=7.
Answer: 1.04 is the density. Explanation: Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. 52.0/50.0=
H2O+Fe⇒Fe2O3+H2
When it is balanced it would be:
3H2O+2Fe⇒Fe2O3+3H2
When balancing equations, you have to make sure that all elements are equal on each side.
