The answer is D, the kinetic energy of the water molecules begins to increase. When you heat up a pot of water, the water molecules begin to move very fast. Thus, stating that the kinetic energy of water molecules increase since the water molecules go from moving a little bit to moving really fast! I hope this could help!
0005 * 0.002 = 5 * 0.002 = 0.010 = 10^-2
Answer:
It is true. a) 0.25 mol
Explanation:
<em>Hello </em><em>there?</em>
To begin solving this problem, you have to write down the chemical equation and make sure it is well balanced.
The chemical equation is;
3Mg(s) + N2(g) => Mg3N2(s)
1 mole of Mg = 24g
We have 18g of Magnesium (Mg) reacting with Nitrogen gas (N2)
From our equation,
Mole ratio = 3 : 1, (Mg : N2)
1 mol Mg = 24g
x mol Mg = 18g
x mol Mg = (18/24) = 0.75 mol Mg
But mole ratio = 3 : 1 (Mg : N2)
This means that 3 => 0.75 mol Mg
What about ratio 1 of N2?
N2 = (0.75 mol ÷ 3)/1
= 0.25 mol N2
<em>I </em><em>hope</em><em> </em><em>this </em><em>helps</em><em> </em><em>you </em><em>to </em><em>understand</em><em> </em><em>better</em><em>.</em><em> </em><em>Ha</em><em>v</em><em>e </em><em>a </em><em>nice </em><em>studies.</em><em> </em><em />
Answer:
The answer is: the body contains chemicals called buffers that resist changes in pH
When you exercise vigorously, the muscle will produce more carbon dioxide which will makes the blood more acidic. Human blood have some mechanism that could prevent the blood pH to stray further from the optimal range. One of the buffer that keep carbon dioxide acidity would be sodium bicarbonate.

Answer:
reactivity
Explanation:
a chemical reacting to another chemical is considered a Chemical property because chemicals react with other chemicals differently
