Answer:
3.45 moles Li contains 2.08
×
10
(to the power of)24 atoms
.
Explanation:
The relationship between atoms and moles is:
1 mole atoms
=
6.022
×
10
(to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022
×
10
(to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45
mol Li

10
(to the power of)23 atoms Li/
1
mol Li
=
2.08

10
(to the power of)24
atoms Li rounded to three
The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. This receptor plays an important role in normal pigmentation. The receptor is primarily located on the surface of melanocytes, which are specialized cells that produce a pigment called melanin.
I believe c. I hope it helps :)
Answer:
No, and yes. As there is a finite amount of matter in the
universe, only so much can be converted to make energy. There will
be a limit, though it is a long, long way from where we are
Explanation:
Answer is <span>
Ni²</span>⁺(aq)
+ 6NH₃(aq)
⇌ [Ni(NH₃)₆]²⁺<span>
</span>
<span>When the concentration of Ni²⁺</span><span>(aq) increases, according to the Le Chatelier’s principle
system tries to become equilibrium by reducing the increased factor. To do
that, the concentration of Ni²⁺</span><span>(aq) should be reduced. Hence, the forward reacted should be
promoted to reduce the Ni²⁺</span><span>(aq) concentration</span>.
