Explanation:
Answer:
Density increases as mass increases, vice versa
Density increases as volume decreases, vice versa
This is because mass, the numerator of the equation, would cause the final answer (density) to increase when it increases, assuming the volume remains constant
And when the denominator of a fraction is large, in this case volume, it would cause the final answer to become smaller!

The correct option is 2.
For a chemical equation to be balanced, the number of atoms of each element present in the reactants must be the same with that present in the products. If the number of atom of any element at any of the two side of the reaction is not the same, then the equation is not balanced. Looking at the options given above, it will be noticed that for option 2, the number of Sr atom at the reactant side is 1 while at the product side it is 2. This shows that the equation is not balanced.
Answer: The Computer: Similarities and Differences. Both use electrical signals to send messages. The brain uses chemicals to transmit information; the computer uses electricity. Even though electrical signals travel at high speeds in the nervous system, they travel even faster through the wires in a computer
