How much heat is absorbed when 30.00 g of c(s) reacts in the presence of excess so2(g) to produce cs2(l) and co(g) according to the following chemical equation?
5 c(s) + 2 so2(g) → cs2(l) + 4 co(g) δh° = +239.9 kj

120.0 kJ

Explanation:

30.00 g C ÷ 12g/mol = 2.5 mol

So when we have half the moles of C (2.5 instead of 5.0), the heat absorbed will also be half, thus the answer is:

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.
