What is the mass of the iron (fe) involved in this reaction? identify the following equations as balanced or unbalanced (4 questions) will give brainliest! and points

This one's just a simple math problem. Do 88 - 32, which is 56. You can also find the same answer by looking for the atomic mass of iron (Fe), which rounds up to 56.

On the left side, there is 2 Nitrogen (because of the subscript), and 6 Hydrogen (3 x 2 = 6). On the right side, there is 2 Nitrogen (because of the coefficient), and 6 Hydrogen. (2 x 3 again) There are 2 Nitrogen and 6 Hydrogen on each side, therefore the equation is balanced.

On the left side, there are 2 Nitrogen (N) and 2 Hydrogen (H). On the right side, there is 1 Nitrogen and 6 Hydrogen. There are 2 Nitrogen and 2 Hydrogen on one side, while the other only has 1 Nitrogen and 6 Hydrogen. Therefore the equation is unbalanced.

On the left side, there are 2 Chromium (Cr) and 6 Chlorine (Cl). On the right side, there are 2 Chromium and 6 Chlorine. There are 2 Chromium and 6 Chlorine on each side, therefore the equation in balanced.

If something is confusing or doesn't make any sense, feel free to let me know! ^^

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

they are all solids.
