Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.
Percentage of abundance of Magnesium = 78.99%
<span>Magnesium- 26 has a percent abundance = 11.01%
</span>
100-78.99-11.01=10%

Answer:
c. 
Explanation:
Hello,
Due to the fact that an odorless gas was released, the chemical reaction between lithium carbonate and a random acid (for instance hydrochloric acid) turns out into:
It is known that carbonic acid is unstable and it quickly decomposes into water and carbon dioxide which is an odorless gas. In spite of the fact that the 
releases 
it isn't the solid since that gas is odorous.
Best regards.
