I'm not sure what the question is asking, but the process would be considered endothermic (it absorbs heat)
Well since chlorine upon receiving a valence electron from the X element, we would know that the element would be a metal, based on the charge of Cl, after it receives a valence electron is -1, the metal would have to give 1 valence electron as well, and thus the possible elements can be any metal within the group 1 of the periodic table of elements. Lithium, Potassium etc.
Answer:
Option A. Double Replacement
Explanation:
A double displacement reaction is a kind of reaction in which there is an exchange of the ions of the two reactants to form a different products. In the equation, K in KOH displaces H in H3PO4 to form K3PO4 and also, the H combines with OH to form water.
H3PO4+3KOH -> K3PO4+3H20
