Answer: The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Explanation:
Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.
Mass of 1 atom of sulphur = 32 g
Mass of 1 atom of oxygen = 16 g
Mass of 2 atoms of oxygen =
In formation of
, 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .
Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
I believe the answers are
1) D
2) B

Solubility of khp in water is greater than many fatty acids because khp is a polar substance while fatty acids are non-polar. Khp has positive and negative charges which help it to dissociate into ions when it dissolves in water. Fatty acids on the other hand contain long unbranched hydrocarbons with one end having a carboxylic acid group. This make water molecules to repel from them because no part of the fatty acid molecules have any charge.

Radiocarbon dating can be used to determine the age of a sample less than 50,000 years old - C
Answer:
- <u><em>Sodium fluoride</em></u>
Explanation:
A <em>solution </em>is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).
<em>Solute</em> is the substace that is dissolved and it is in less amount than the solvent.
<em>Solvent</em> is the substance that can dissolve the solute and it is a greater amount than the solute.
In the given solution:
- <em>sodium fluoride</em>, <em>85.0 mL</em>, is the solute,
- <em>water</em>, <em>350.0 mL</em> is the solvent, and
- the mixture of both substances is the solution.
