The kinetic theory states that matter consists of particles in constant motion.
Answer:
Chemistry is the branch of science that deals with the properties, composition, and structure of elements and compounds, how they can change, and the energy that is released or absorbed when they change. Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic and Biochemistry. Chemistry is involved in everything we do. The reason why chemistry touches everything we do is because almost everything in existence can be broken down into chemical building blocks.

The volume of the box is 8.6 × 10³ in².
<em>V = lwh</em> = 26 in × 18.4 in × 17.92 in = 8.6 × 10³ in²
<em>Note</em>: The answer can have only <em>two significant figures</em> because that is all you gave for the length of the box.

Answer:
X3Y2
Explanation:
To represent the chemical formula of the binary compound, the valencies of both elements need to be exchanged.
Valency is the combining power of elements, ions or radicals. It is the value that shows how an element tend to combine with other elements.
In this particular question, the valence of the element X is +2, this means when it enters into chemical combination, it goes in with the power of positive 2. Same goes for the element Y, when it goes into chemical combination, it is expected that it goes in with the negative power of 3.
To completely write the chemical formula of the compound formed from the combination of both, we simply exchange the valency as said above. It must be noted that while the less electronegative element carry a positive or less negative charge , the more electronegative element will carry a negative or more negative charge.
We write the less electronegative element before the more electronegative element while writing the formula of the compound
