Which of the following reactions involves the transfer of electrons?
a. synthesis
c. combustion
b. decomposition
d. reduction-oxidation

A reduction-oxidation reaction involves a transfer of electrons.

Explanation:

In a reduction-oxidation reaction there are two chemical compounds, one of them gain electrons and is called the oxidizing agent, and the other lose electrons and is called the reducing agent.

The oxidizing agent is the compound that is reduced it means that its oxidation number decreases and the reducing agent is the compound that is oxidized or in other words is the compound which its oxidation number increases.

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
