Answer:
they have differnet properties that repeat across the next period
Explanation:
Answer:
6-
because X has only one positive charge.
7-
because there is increase in hydroxyl ions which decrease the acidity or hydrogen strength of hydrochloric acid.
8-
Calcium has a valency of 2 and nitrate ion radicle has valency of 1
Answer:
The answer is C. six months
Explanation:
I hope this helps you bestie:))
Answer: or Sodium carbonate.
or Potassium permanganate
Explanation: ion carries 1 + charge whereas carbonate ion carries overall charge of -2. So for every carbonate ion, two sodium ions combine to balance the charges and thus form a stable compound,
Potassium ion carries 1 + charge where as permanganate ion carries overall charge of -1. So for every permanganate ion, one potassium ion combines to balance the charges and thus form a stable compound, Explanation:
I think it is kinetic energy
