Answer:
There are 3 atoms in the 50 moles of Al
Explanation:
Answer: option B) They provide an alternate lower energy mechanism by which the reaction proceeds
Explanation:
Catalyst are involved in chemical reaction increasing the rate they occur by lowering the activation energy found in the bound- reactants complex.
The reaction moves forward because the lower energy mechanism when catalyst are added allows for a more easily splitted bond, thus, allowing the formation of products.
One mole of any gas under STP has volume 22.4 L,
so 22.4 L N2 under STP contains 1 mole of molecules N2.
Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.
