Please help if u can ty..

a)

b)

c)

d)

e)

Explanation:

The charges of the ions have to be 0, so they balance.

a) has the charge of +2 and has the charge of -1. So its . That means you need one and two to balance the equation. ->

b) has the charge of +4 and has the charge of -1. So its . That means you need one and four to balance the equation. ->

c) has the charge of +3 and has the charge of -2. So its . That means you need two and three to balance the equation. ->

d) has the charge of +2 and has the charge of -2. So its . That means you need one and one to balance the equation. ->

e) has the charge of +1 and has the charge of -3. So its . That means you need three and one to balance the equation. ->

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

catya your not at all which answer i've seen you do this on another question!
