I think the chemical reaction is:<span>
N2H4 + 2 H2O2-> N2 + 4H2O
We are given the amount reactants allowed to react. This will be the starting point of the reaction. First, is to find the limiting reactant.
9.24 g H2O2 ( 1 mol / 34.02 g ) = 0.27 mol H2O2
6.56 g N2H4 ( 1mol / 32.06) = 0.20 mol N2H4
Since from the reaction we have 1:2 ratio of the reactants then the limiting reactant is hydrogen peroxide. We will use this to find the amount of N2 produced.
0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2) =1.89 g N2

Answer: The stratosphere!!
Answer:
The answer to your question is Protons = 36, Neutrons = 26, Electrons = 36
Explanation:
⁷⁰Se²⁻
The number of protons is equal to the atomic number, Selenium has an atomic number of 34. Then the number of protons = 34.
The number of neutrons = Mass number - number of protons
= 70 - 34
= 36
The number of electrons = number of protons + 2 because of the 2- next to the symbol of Selenium.
Number of electrons = 34 + 2
= 36
<span>It is a buffer because pH = pKa of formic acid. </span>
The answer is NO. It can not be a compound it is an element.
In a component mixture it can be separated physically way from the other.
In element it can be only separated by a way of destroying the compound itself by chemical reaction.
