Which is the balanced chemical equation showing hydrogen peroxide (H2O2) decomposing into hydrogen (H2) and oxygen (O2)? Multipl
Vlad1618 [11]

Answer: H_2O_2\rightarrow H_2+O_2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for showing hydrogen peroxide decomposing into hydrogen and oxygen is:

H_2O_2\rightarrow H_2+O_2

Use the mass and volume data to calculate the density of an unknown metal to the nearest hundredth. Mass of unknown metal = 222.
Colt1911 [192]
0.90g /cm^2
Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. To calculate for the density of the unknown metal, we simply divide the mass of the substance by the volume measured. We do as follows:

Density = mass / volume
Density = 222.50 g / 25 mL
Density = 8.9 g/mL
