Answer:

2. It helps us to eliminate waste

3. It helps regulate our body temperature

Explanation:

In addition to the function of bringing nutrients to the cells, water provides the elimination of substances out of the body. This occurs, for example, through urine, which is basically formed by water and toxic or excess substances dissolved.

Water also helps in regulating body temperature. This occurs when the heat becomes exaggerated, sweat is released, which has water in its composition. When in contact with the medium, the sweat evaporates on the surface of the skin, causing the body to cool.

First we have to understand what a half life is. A half life is a measure of time when the amount of a certain object is 50% of the original amount. Hence the answer for this is letter A. The initial amount is 100. fifty percent of 100 is 50 and that happens after 15 hours. Hence, 15 hours is the half life period.

The mixing of which pair of reactants will result in a precipitation reaction? A. Ba(NO3)2(aq) + Na2CO3(aq) B. NH4Br(aq) + NH4I(
Semenov [28]

Answer:

A. Ba(NO₃)₂(aq) + Na₂CO₃(aq)

Explanation:

  • The reaction between aqueous Ba(NO₃)₂ and Na₂CO₃ is a precipitation reaction.
  • The complete equation for the reaction is;

Ba(NO₃)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + NaNO₃(aq)

  • Barium carbonate is the precipitate formed during the reaction.
  • All nitrates are soluble in water and all salts of sodium are soluble in water, therefore, Ba(NO₃)₂, Na₂CO3, and NaNO₃ are soluble in water.
  • Precipitation reaction involves reaction of soluble salts to form a precipitate as one of the product.
