Answer:

We have:

(

→

(

(

)

LHS

Mg= 1

H= 1

Cl= 1

RHS

Mg= 1

Cl=2

H=2

To make Cl and H have 2 on both sides, we place a 2 in front of the HCl

(

)

→

(

)

(

)

LHS

Mg=1, H=2, Cl=2

RHS

Mg=1, H=1, Cl=2

Thus the equation is balanced and the coefficient of Mg is 1, which is understood so it is not written in the final equation.

Why do sea and ocean levels recede (more coast land is exposed) when the planet goes through a major ice age?

fomenos

This happens because ice is made up of water, and when that water freezes, it never goes back to land, thus there being less water on the coastline. But when the ice starts to melt, the water will even out quickly, and the water will go to the coastline, causing the tide to rise. Mark brainliest, please.
