The answer is: 87
i have to type other letters so blah blah blah... i hope this helps you:)
The subscript 3 outside of the parentheses means to multiply everything in the parentheses by 3, so it becomes a matter of addition:
3*(CH3) * (1 carbon atom)/(CH3) = 3 carbon atoms in (CH3)3
CH has one carbon atom and one hydrogen atom, so:
1 carbon atom in CH
Add both of them together, and you get 4 carbon atoms in isobutane
In a chemical reaction, the difference between the potential energy of the products and the potential energy of the reactants is equal to the heat of the reaction<span>. This is, the net energy released or absorbed (change) during a chemical reaction is the sum of the potential energy of the products less the sum of the potential energy of the reactants.</span>
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.
