2 K + Cl2 → 2 KCI
How many grams of KCI (74.55 g/mol) is produced from 2.50 mol of K?

 186.3 g of will be produced from 2.50 mol of K

Explanation:

The balanced chemical reaction is:

According to stoichiometry :

2 moles of K produce = 2 moles of

Thus 2.50 moles of will produce=  of

Mass of

Thus 186.3 g of will be produced from 2.50 mol of K

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
