Answer:
<em><u>= - 0.38 eV</u></em>
Explanation:
Using Bohr's equation for the energy of an electron in the nth orbital,
E = -13.6 
Where E = energy level in electron volt (eV)
Z = atomic number of atom
n = principal state
Given that n = 6
⇒ E = -13.6 × 
<em><u>= - 0.38 eV</u></em>

I’m pretty sure it is number of protons
Answer : Chemicals A and B form an endothermic reaction, and chemicals C and D form an exothermic reaction.
Explanation :
Endothermic reaction : When the system absorb heat from the surrounding then the surrounding become cool.
Exothermic reaction : when the system releases heat into the surrounding then the surrounding become hot.
According to the question,
when we mixed chemical A and chemical B together in a test tube to form chemical C, the mixture become cool. This means that the system is absorbing heat from the surrounding and thus the reaction is called a endothermic reaction.
And when we added chemical D in chemical C, the new mixture becomes hot and explodes. This means that the system is releasing heat into the surrounding and thus the reaction is called as exothermic reaction.
The question is incomplete as it does not have the option which are:
A. A coenzyme.
B. An allosteric inhibitor.
C. The substrate.
D. An intermediate.
E. A competitive inhibitor.
Answer:
An allosteric inhibitor.
Explanation:
An allosteric inhibitor is a molecule which binds to the site other than the active site but inhibits the action of the Enzyme and thus the product.
The allosteric inhibitor is considered a non-competitive inhibitor which after binding to the enzyme cause some conformational changes which further changes the structure of the active site and thus substrate no longer binds the enzyme. This molecule thus inhibits the production.
Thus, An allosteric inhibitor is correct.
