If your question means "How can you tell if a substance is a binary compound?"
<span>Then I'll answer this.
A binary compound is a chemical compound composed of only two elements.

Sulfur dioxide gas reacts with water to form sulfurous acid. Sulfurous acid readily dissociates in water. As the sulfur dioxide gas dissolves in the reaction, the capillary action of the test tube causes water to replace the gas inside the tube. The dissolution of sulfuric acid gas creates a vacuum inside the tube causing the water to rise inside.
Answer:
Relative abundance of each isotopes of an element.
Explanation:
Consider the following example:
Uranium is used in nuclear reactors and is a rare element on earth. Uranium has three common isotopes. If the abundance of 234U is 0.01% the abundance of 235U is 0.71% and the abundance of 238U is 99.28% what is the average atomic mass of uranium
Abundance of U²³⁴ = 0.01%
Abundance of U²³⁵ = 0.17%
Abundance of U²³⁸ = 99.28%
Average atomic mass = ?
Solution:
Average atomic mass of uranium = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) +(abundance of 3rd isotope × its atomic mass) / 100
Average atomic mass of uranium= (234×0.01)+(235×0.71)+(238×99.28)/100
Average atomic mass of uranium= 2.34 + 166.85 + 23628.64 / 100
Average atomic mass of uranium= 23797.83 / 100
Average atomic mass of uranium= 237.98 amu.
Don’t understand lol... but I’m chasing those points so thanks
