The volume of the marble is 2.3 cube units.
From the question given above, the following data were obtained:
The volume of the marble can be obtained as follow:
V = L × W × H
V = 1.32 × 1.32 × 1.32
V = 2.3 cube units
Thus, the volume of the marble is 2.3 cube units.

The correct ratio of the atoms of the two elements in the sample of copper chloride compound would be 1:2.
<h3>Atoms of elements</h3>
Copper chloride has a chemical formula, 
.
Thus, an atom of copper, Cu, combines with 2 atoms of chlorine, Cl.
The 2 chlorine atoms are recipients of an electron each from the copper atom which happens to have 2 electrons in its outermost valence shell.
Therefore, the ratio of copper to chlorine atoms in the compound is 1:2.

Answer:
40.3∘C
Explanation:
At planet B;
Water boils = 180∘C
Water freezes = 50∘C
In this planet the temperature difference = 180 - 50 = 130 compared to earth where the temperature difference is; 100 - 0 = 100
This means;
130 ∘C = 100 ∘C
x ∘C = 31 ∘C
x = 31 * 130 / 100
x = 40.3∘C
<span> These three concepts of inertia, </span>mass<span>, and weight are interconected. Intertia can be defined by Newton's first law, which states that "an object at rest will remain at rest and an object in motion will remain in motion." In other words, inertia is the amount of resistance an object has to change.</span>
His model describes the reactivity of an element based on its number of valence electrons is the right answer but I don’t know what the other is.
Hope this helps:)
