During a strenuous soccer game, a student is sweating a lot. Which of these would help her maintain her water balance? A. drinking more water or other fluids

B. wiping off perspiration with a towel

C. increasing breathing and heart rate

D. refraining from drinking any water

A

Explanation:

because your body needs to have an intake in the volume of liquids, and when you sweat it secretes the water from your body

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
