Answer:
A decomposition reaction is a reaction in which the compound is broken up into its constituents.
A decomposition reaction is a reaction in which the compound is broken up into its constituents. When the decomposition is brought about by a catalyst, it is called catalytic decomposition.
Let us look at the catalytic decomposition of the compound potassium trioxochlorate V. in the presence of the catalysts manganese dioxide. The reaction occurs as follows;
2KClO3 -----> 2KCl + 3O2

Answer:
C) 1 x 10-10 M
Explanation:
To solve this question we must use the equation:
Kw = [H+] [OH-]
<em>Where Kw is the equilibrium dissociation of water = 1x10-14</em>
<em>[H+] is the molar concentration of hydronium ion = 1x10-4M</em>
<em>[OH-] is the molar concentration of hydroxyl ion</em>
<em />
Replacing:
1x10-14= 1x10-4 [OH-]
<em>[OH-] = 1x10-14 / 1x10-4M</em>
<em>[OH-] = 1x10-10 M</em>
Right option is:
<h3>C) 1 x 10-10 M
</h3>
Answer:Option (3) less than the sum of its components' masses
Explanation:
<span>17.5 g
35 ppt stands for 35 parts per thousand. So let's convert that to a decimal number by taking 35 and dividing by 1000.
35/1000 = 0.035
Now multiply that number by the number of grams of seawater you have. So
0.035 * 500 g = 17.5 g
So you have 17.5 grams of salt when you have 500 grams of seawater.</span>
