He knows that the reaction might be happening too slowly to see results in a
few minutes. Which action should Noah take to speed up the reaction?
A. Replace the piece of zinc with a larger piece.

B. Decrease the concentration of the copper sulfate solution

C. Decrease the temperature of the solution.

D. Increase the concentration of the copper sulfate solution.​

A. the place that piece of with a larger piece

Explanation:

Sana nakatulong

D. Increase the concentration of the copper sulphate.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
