Although the information might be true, it might be twisted or presented in such a way that it makes the product more appeasing
Mass = PROTONS + neutrons. So, 19 +20 = 39.
(Don't confuse yourself between electrons and protons when they are equal because it could be an ion)
Explanation:
i think it is exothermic processes
As we can see the chemical equation is balanced.K3PO4 + Al(NO3)3 → 3KNO3 + AlPO4
So, by principle of conservation of mass when 1 mole of K3PO4 reacts with 1 mol of Al(NO3)3 , it peoduces 3 mol of KNO3 and 1 mol of AlPO4
So, when 2.5 moles of potassium phosphate react and Al(NO3)3 is present in excess , 2.5*3= 7.5 mol of KNO3 is formed
