C) the number of the pricipal energy level containing the outer electrons increases
<u>Answer:</u> The final volume of the reaction is 4.69 L
<u>Explanation:</u>
The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.
The equation used to calculate number of moles is given by:

where,
are the initial volume and number of moles
are the final volume and number of moles
We are given:

Putting values in above equation, we get:

Hence, the final volume of the reaction is 4.69 L
<span>molecular weight of Ca(NO3)2 --> 164
Ca=40
N=14
O=16
molecular weight of Li3PO4 --> 115.8
molecular weight of LiNO3 --> 68.9
Ca3(PO4)2 produced ---> 310.2 g/mol molecular weight
Hence the answer would be 310.2 g/mol of calcium phosphate will be produced</span>
Answer: You can calculate the pH of an acid or base solution given the hydronium ion concentration by using the formula pH = -log [H3O+] or if given the hydroxide ion concentration by the formula [H3O+] = Kw / [OH-], then using the pH = -log [H3O+] formula.
