Titanium dioxide, tio₂, reacts with carbon and chlorine to give gaseous ticl₄: tio₂+2c+2ci₂−tici₄+2co the reaction of 7.39 kg titanium dioxide with excess c and cl₂ gives 14.24 kg titanium tetrachloride. calculate the theoretical yield of ticl₄ (assuming complete reaction) and its percentage yield.

17.57kg of and its percentage yield is 81.0%

Explanation:

Through the reaction you can get the theoretical amount of   that must be produced.

If the amount obtained is less than the theoretical amount, it means that the initial sample was not 100% pure. Now the actual amount obtained is compared with the theoretical amount using a percentage

=81.0%

wher is the rest of the question

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
