Electrons are found in the cloud that's surrounded the nucleus of an atom
Answer:

Explanation:
We will need a balanced chemical equation with masses, moles, and molar masses.
1. Gather all the information in one place:
Mᵣ: 18.02
2Na + H₂O ⟶ 2NaOH + H₂
m/g: 72.0
2. Moles of H₂O

3. Moles of Na
The molar ratio is 2 mol Na/1 mol H₂O.

Chemical weathering can be caused by oxidation, dissolution, and hydrolysis
Answer:
the dividend yield is 4%
Explanation:
The computation of the dividend yield is as follows:
Dividend yield = Dividend per share ÷ current share price per share
= ($0.20 × 4 quarters) ÷ $20
= $0.80 ÷ $0.20
= 4%
hence, the dividend yield is 4%
The same is determined by applying the above formula
