Explanation:
Answer:The mole ratio is A:B:A+B
Explanation:when substance reacts according to John Dalton's theory,their combining ratio is often a replica of the combining moles of the reactants and that of the products. So when Amoles of X combines withB moles of Y ,they produce A+B moles of XY to get a balance reaction e.g if 1moles of X2 reacts with 1moles of Y2 to form XY
The balance equation is seen as
X2+Y2_____2XY
