Answer:
3) 2KOH + H2SO4 → K2SO4 + 2H2O
Explanation:
The balanced chemical equation for the reaction of KOH and H2SO4 is,
→ 2KOH + H2SO4 → K2SO4 + 2H2O
Hence, option (3) is the correct answer.
Electrons are shared, thus it is a covalent bond.
The ph of the 1M solution of NaC2H302 is 9.37
The cycling of water and nutrients through an ecosystem is powered mainly by the sun, while the cycling of blood in the cardiovascular system "powered" by the heart.
