Sati [7]

Answer:

Swelling of the red blood cells occurs.

Explanation:

  • <u>Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body  tissues including  the red blood cells. </u>
  • Therefore the water will enter the red blood cells and may cause them to lyse or swell.
  • <em>Additionally , water will enter the tissue spaces and cause sweling. </em>
  • But in the case of a hypertonic solution , ( a salt or saline solution ) , <em>This swelling does not happen because the concentration of the saline will be equal or more than the blood. </em>
  • Thus the water will flow only from the blood to the solution. <u>This will not cause swelling.</u>
  • But too much of salt is also not recommended.

When two ammonium nitrate molecules collide with each other and then chemically decompose as a result, how many NEW molecules (i
Lunna [17]

The collision and decomposition of 2 ammonium nitrate molecules results in the formation of 2 molecules of N_2O and 4 molecules of H_2O

<h3>Decomposition reaction</h3>

Ammonium nitrate decomposes to produce nitrous oxide and water according to the following equation:

NH_4NO_3 --- > N_2O + 2H_2O

In the above, a mole of ammonium nitrate decomposes to form a mole of nitrous oxide and 2 moles of water.

If moles of ammonium nitrate decomposes, the equation becomes:

2NH_4NO_3 ---- > 2N_2O + 4H_2O

Thus, 2 moles of nitrous oxide and 4 moles of water would be formed.
