Answer:

The answer to your question is Cr₂O₃  +  3Mg  ⇒   2Cr  +  3MgO

Explanation:

Data              

Unbalanced chemical reaction

               Cr₂O₃  +  Mg  ⇒   Cr  +  MgO

           Reactants        Elements       Products

                  2                      Cr                 1

                  3                       O                 1

                  1                        Mg               1

Balanced chemical reaction

               Cr₂O₃  +  3Mg  ⇒   2Cr  +  3MgO

           Reactants        Elements       Products

                  2                      Cr                 2

                  3                       O                 3

                  3                        Mg              3

Now the reaction is balanced

Which statement best describes the compressibility of a gas? A Increasing the temperature of a gas decreases the pressure. B Inc
k0ka [10]

The answer is C. Compressing the air reduces the volume and increases the pressure. Compressing the air causes the molecules to collide with one another, and with the walls of the container, at a higher frequency. This is becaue the number of molecules are still the same but now forced in a smaller volume of space. This why the pressure increases wiht reduced volume, while keeping the temperatures constant.
