Answer:
See Explanation
Explanation:
For SF6;
Since;
1.25 g of S corresponds to 4.44g of F
1 g of sulphur corresponds to 1 * 4.44/1.25 = 3.55
For SF4;
Since;
1.88 g of S corresponds to 4.44g of F
1 g of sulphur corresponds to 1 * 4.44/ 1.88 = 2.36
Hence;
Mass of oxygen per gram of sulphur in SF6/Mass of oxygen per gram of sulphur in SF4
=
3.55/2.36 = 1.5
Hence the law of multiple proportion is obeyed here.

Answer:
M₂ = 0.08 M
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 0.500 M
Final volume = 150.0 mL
Final molarity = ?
Solution:
Formula:
M₁V₁ = M₂V₂
0.500 M × 25.0 mL = M₂ × 150.0 mL
M₂ = 0.500 M × 25.0 mL / 150.0 mL
M₂ = 12.5 M.mL /150.0 mL
M₂ = 0.08 M
Answer:
Yes.
Explanation:
"These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products."
There is a beginning product, and a reactant is needed in order for something to happen.
For example, according to Newton, something cannot happen until an exterior force comes and stops/pushes it.
Sorry if this is incorrect, I am just 4th grade :(
