What is an electrically charged atom? A. ion B. isotope C. molecule D. compound
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
When a neutral atom loses an electron then it acquires a negative charge and if a neutral atom gains an electron then it acquires a positive charge. Hence, an ion is formed in both the cases.
For example, sodium on losing an electron become ion.
An isotope is defined as the specie which contains same number of protons but different number of neutrons.
For example, and
are isotopes.
A molecule is defined as a substance that contains chemically combined two or more number of atoms of an element.
For example, is a molecule.
Whereas a compound is defined as a substance in which different atoms of different elements chemically combine together in a fixed ratio by mass.
For example, is a compound.
Thus, we can conclude that an ion is an electrically charged atom.

The Balanced chemical equation of reaction of Borane with oxygen is as follow,
B₂H₆ + 3O₂ -----> 2HBO₂ + 2H₂O
According to this equation 27.66 g (1 mole) of B₂H₆ reacts with oxygen to produce 36 g (2 moles) of water.
The amount of water produced when 19.2 g of B₂H₆ reacted is calculated as follow,
= 
Solving for x,
x = (36 g of H₂O ₓ 19.2 g of H₂B₆) / 27.66 g of B₂H₆
x = 24.98 g of H₂O
Result:
24.98 g of water is produced when 19.2 g of B₂H₆ is reacted with excess of oxygen.
