Answer:
They went from atoms to oxygen molecule.
Explanation:
I'm not sure if this is the answer your teacher is looking for, but in simple terms you had 2 oxygen atoms. Together they make an oxygen molecule, which is the stuff we breathe.

Answer:</h3>
Molarity is 0.046 M
<h3>
Explanation:</h3>
We are given;
1.72 mol of LiCl in 37.5 L of solution
We will take the question to be; calculate the molarity of LiCl
Therefore,
we can start by defining molarity as the concentration of a solution in moles per liter.
Molarity of a solution is calculated by dividing the number of moles of solute by the volume of solution.
Molarity = Moles of solute ÷ Volume of the solution
Thus, in this case;
Molarity of LiCl = Moles of LiCl ÷ Volume of the solution
= 1.72 moles ÷ 37.5 L
= 0.0459 M
= 0.046 M
Therefore, the molarity of LiCl solution is 0.046 M
Heat energy is the amount of heat there is in a substance. This may be cold heat or warm heat. Temperature is how hot or cold a substance is. So because there is a higher volume of heat in the iceberg, we say it has more heat energy.
CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
