Mg+2HCl-->H2+MgCl2 you would it have to make it so each is equal on each side you would add a 2 on left in front of HCl because on the other side there is already 2 H and 2Cl so just put a 2 in front of HCl

lana [24]

Answer:

active transport

Explanation:

Active transport -

It refers to the movement of the molecules from a region of lower concentration towards a region of higher concentration via a membrane , is referred to as active transport.

The process of active transport need to have some cellular energy .

Hence,

The concentration of potassium is maintained in the red blood cells via the process of active transport.

One of the chair conformers of cis-1,3-dimethylcyclohexane is 5.4 kcal/mol less stable than the other. How much steric strain do

Karolina [17]

Answer:

See explanation

Explanation:

the Cis structure, we can have two possibilities. The methyl groups can go both in axial positions or both in equatorial positions. We have to remember that cis it means "same orientation", so in the axial positions, both methyl groups go up. (Both have the same orientation). In the equatorial positions, both groups go down.

In the axial positions, we will have more steric hindrance because the groups are close to each other. Therefore, we will have more energy and the structure will be less stable. In the equatorial positions, we dont have any steric hindrances, so we will have less energy and more stability.

See figure 1

I hope it helps!
