I believe you mean 1.02*10^24 so I did
1.02*10^24/(6.02*10^23) * 54.938. I got d) 9.31*10^1 g as my answer.
The chemical formulas for their respective substances are the following:
Cadmium Sulfide: CdS
Sulfuric Acid: H₂SO₄
Hydrogen Sulfide: H₂S
This is a double replacement reaction where the substances of the reactants interchange to yield two products. The complete balance reaction would be:
<span>CdS (s) + H</span>₂<span>SO</span>₄<span> (aq) ----> CdSO</span>₄<span> (aq) + H</span>₂<span>S (g)
</span>
The other product is Cadmium Sulfate.
Explanation:
In a Lewis dot diagram, the electrons are arranged so that, when full, two electrons placed beside each other are on four sides of the element symbol.
An electron is 3-dimensional, so you can start on any side on a 2D diagram.
Continue this pattern depending on how many electrons you have:
When adding an electron after the first, it is placed on the next side going either counterclockwise or clockwise. Which ever direction you choose, be consistent.
After the fourth electron, so that one electron is on each side, place a dot beside your first electron and continue the pattern.
