If they're different sizes and densities, you are able to separate the substances.
Explanation:
The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.
Answer:
PE ( Potential Energy ) = Mass x Gravity x Height
Explanation:
For the first one you would do.
.28 ( mass) x 9.8 ( constant of gravity ) x .40m ( height )
So just multiply your Mass, Gravity and Height together and you will get Potential Energy
Gravity is always 9.8 m/s
