Write an equation that shows the reaction between acetic acid (ch3cooh) and triethylamine (ch3ch2)3n. draw all non-bonding lone electron pairs and show the electron flow with curved arrows.

Due to the lone pair of electron present on nitrogen in ethylamine, it will behave as base and attack on the hydrogen of hydroxy group of acetic acid, which is an acid and results in the formation of conjugate acid of triethyl amine and conjugate base of acetic acid.

The reaction between triethylamine and acetic acid is shown in the attached image.

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.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
