What is the correct ratio of the atoms of the two elements present in a sample of the compound copper chloride, CuCl2?
1 answer:
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: Option (B) is the correct answer.
Explanation:
Expression for the given decomposition reaction is as follows.
Let us assume that x concentration of is present at the initial stage. Therefore, according to the ICE table,
Initial : x 0
Change : - 0.1
Equilibrium : (x - 0.1) 0.2
Now, expression for of this reaction is as follows.
Putting the given values into the above formula as follows.
x = 0.12
This means that = x = 0.12 atm.
Thus, we can conclude that the initial pressure in the container prior to decomposition is 0.12 atm.
