What is chemical Compound?</h3>
Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
During formation of a compound calcium act as cation as Ca²⁺ so, if any element has to react with this cation in a 1:1 ratio, must have -2 charge over it . Option C represents S⁻², which react with Ca²⁺.
Therefore, the correct option is option C.

Answer:
0.01932 L
Explanation:
First we <u>convert 105 mM to M</u>:
Next we <u>convert 552 mL to L</u>:
Then we use the following equation:
Where:
We<u> input the given data</u>:
- 3 M * V₁ = 0.105 M * 0.552 L
And <u>solve for V₁</u>:
Two parts are stage and coarse focus
