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

Yes and im usually sooooo happy to see it.
From another answer, it is most likely E. Horizon. Hope this helps!
Answer;
H- (negatively charged hydrogen ion)
Explanation;
The hydrogen ion has the same electron configuration as an atom of Helium. -Hydrogen ion is formed when a hydrogen atom loses or gains an electron. A positively charged ion is formed when hydrogen atom loses an electron (remaining with zero electrons) while a negatively charged ion (H-) is formed when a hydrogen atom gains an electron thus having 2 electrons.
-Helium atom has two electrons, therefore, it is similar with an negatively charged hydrogen.
