Answer:
A helium atom has no charge, which means it has an oxidation number of 0. ... Since the numbers of protons and electrons are equal, the positive charge of the protons and the negative charge of the electrons add up to zero.
Step-by-step explanation:
28
You times 8/3 and 21/2 to get 28
x = 1, 3
Explanation:
Thus, there are two solutions and the values are <u>1</u> and <u>3</u>
2
-7 - (-8) = 1
1 + (-3) = -2
-2 + 6 = 4
4 - 2 = 2
In order from least to greatest, it goes 4/5, 0.81, 90%
