Hi there!
The 6 branches of chemistry are Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, Physical Chemistry, Biochemistry, and <span>Nuclear Chemistry.
</span>Organic Chemistry: The branch of chemistry dedicated to carbon compounds and substances.
Inorganic Chemistry: <span> The branch of chemistry dedicated to non-carbon compounds and substances.
</span>
Analytical Chemistry: The branch of chemistry dedicated to identifying and quantifying matter through a variety of different instruments, tools, and practices.
Physical Chemistry: The branch of chemistry dedicated to analysis of chemical phenomena as well as their different behavior and phenomena.
Biochemistry: <span> The branch of chemistry dedicated to the chemical processes such as cellular respiration that occur within living organisms.</span>
Nuclear chemistry: <span> The branch of chemistry dedicated to nuclear processes and properties as well radioactivity.</span>
They are called isotopes.
Answer:
B. Identify solutions to the problem.
Explanation:
In the case described above, the engineer has already designed and attempted to manufacture a prototype for the process. The design of the process must have also been carefully researched and planed.
However, he identified the problem of low yield and is now working towards identifying solutions to the problem. One option he seeks to explore according to the question is to change the catalyst used in the reaction.
Answer:
The chemical elements most likely to form covalent bonds are those that share electrons, such as carbon, as opposed to those that take them from another element to form an ionic bond. In general, they are nonmetals with similar electronegativities.
Explanation:
2Fe(OH)3 → Fe2O3 + 3H2O
There are 2 iron atoms on the left,
and 2 iron atoms on the right. There are 6 oxygen atoms on the left, and 6
oxygen atoms on the right. There are 6 hydrogen atoms on the left and 6
hydrogen atoms on the right.
This equation is balanced.
2Al(OH)3→ Al2O3+ 3H2O
There are 2 aluminum atoms on the
left, and 2 aluminum atoms on the right. There are 6 oxygen atoms on the left,
and 6 oxygen atoms on the right. There are 6 hydrogen atoms on the left and 6
hydrogen atoms on the right.
<span>This equation is balanced.</span>
