A plant is burning limestone which analyzes 52% CaO, 41% CO2 and 7% inerts using coke that analyzes 90% C and 10% ash. The lime product obtained contains 3% CO2 and 1% unburned C. The top gas shows 24.1% CO2, 1% CO ad 74.9% N2. a. The kg limestone/kg coke is about .

b. The lime-fuel ratio is about .

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.  

a:

by the combination of an unlimited number of elements

since electrons are negative the answer is neagtaive
