Explanation:
We are given with the following pairs:
<span>carbon and oxygen
hydrogen and helium
gold and silver
and we are asked if there is a pair that will produce the same spectrum. The answer is
</span>No two elements produce the same spectrum.This is because a light spectrum is unique to each element.
I think it’s C because those elements tend to gain electrons while the deepest shade of green tend to give electrons
The formula for beryllium chlorite is Be(ClO2)2.
The beryllium cation has a charge of 2+ and a chlorite ion has a charge of 1-. Using the crisscross method, we move the charge of the beryllium cation to the subscript position of the chlorite ion and the charge of the chlorite ion to the subscript position of the beryllium cation. So, we get Be1(ClO2)2. The ratio one-to-two cannot be reduced further. Since the subscript of Be is 1, we drop it and get Be(ClO2)2.
