Answer:
7.1
Explanation:
equation to calculate pH is

Balanced chemical reaction: 2K(s) + 2H₂O(l) → 2KOH(aq) + H₂(g).
KOH is inorganic compound p<span>otassium hydroxide, a strong base.
H</span>₂ is hydrogen gas.
In balanced chemical reaction number of atoms on both side of chemical reaction must be same. There are two potassium atoms, four hydrogen atoms and two oxygen atoms on both side of reaction.
Explanation:
molarity = no. of moles of solute/solution in litres
molarity =0.202/7.98
=0.025 M
I think u turn down the heat not to sure
Electric energy converted to light energy
