Yes, if we're talking about intramolecular bonds
Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of = Total mass of
As we are given :
Total mass of = 65.7 grams
So,
65.7 grams = Total mass of
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
Yes the answer is true as long as it combines physically and not chemically to form the new substance which would then called a mixture.

Answer:
2.18x10^-9 M
Explanation:
From the question given,
Hydrogen ion concentration, [H+] = 4.59x10^-6 M
Hydroxide ion, [OH-] =?
The hydroxide ion concentration, [OH-] in the solution can be obtained as follow:
[H+] x [OH-] = 1x10^-14
4.59x10^-6 x [OH-] = 1x10^-14
Divide both side by 4.59x10^-6
[OH-] = 1x10^-14 / 4.59x10^-6
[OH-] = 2.18x10^-9 M
This is a neutralisation reaction, so we know that the products formed are salt and water.
First, we balance the chemical equation:
KOH + HNO3 ----> KNO3 + H2O.
After that, we split the compounds into their respective charges.
K+ + OH- + H+ + NO3- ----------> K+ + NO3- + H2O*
(*note that liquid cannpt be splitted.)
After that we reduce the chemical equation by removing the common ones.
OH- + H+ --------> H2O
Tada.
