Answer:
1. The oxidation number of Ca is 2, F is -1 in CaF₂
2. The oxidation number of H is 2, S is 6, O is -8 in H₂SO₄
3. The oxidation number of Ca is 2, S is 6, O is -8 in CaSO₄
4. The oxidation number of H is 1, F is -1 in HF
Explanation:
To get the oxidation number, we need to take the oxidation number of the whole compound 0. Then we need to know the oxidation number of the other elements and we need to take 'x' as the oxidation number of the unknown element.
Example:
In case of CaSO₄,
We can write an equation as-
CaSO₄ = 0
If we need to know the oxidation number of S
We can write the equation like this-
→2+ x+ (-2*4) = 0 (as we know the oxidation number of Ca is 2 as it has two electrons in its last shell which it gives to other elements to form bonds and the oxidation number of O is -2 as it takes 2 electrons to complete its outer shell)
→2+ x+ (-8) = 0
→2+ x- 8 = 0
→x- 6 = 0
→x = 6; which is the oxidation number of S

Answer:
B. 26%
Explanation:
According to the Chargaff rule, we know that the quantity of thymine and adenine, and the quantity of cytosine and guanine are exactly the same in the DNA.
We can conclude that if there is 24% of thymine, there is also 24% of Adenine. Because <u>those bases pair with each other</u> and there is going to be the same percentage of them both in the DNA.
The sum of the 4 bases is going to be 100% in the DNA
Since 24% of the organism is thymine 24% is going to be adenine
To know how much is missing from the equation we would have to subtract the total 48%
This means that the remaining 52% is composed by the cytosine-guanine pairs. Since the pairs are equal in quantity in the DNA, we have to divide this number by 2 to have the amount of each one
The answer is: B.26% is going to be the percent of cytosine and also guanine in the DNA
