<u>Answer:
</u>
When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>
<u>Explanation:</u>
Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.
We have to convert the researcher's volume into the SL units of liter.
<em>So, we know that 1 gallon = 3.875 liters</em>.
Then we have to convert 2.90 gallons of water in to liters.
Then , volume in L =
= 
= 
<em>Then the required volume in 
</em>
Answer:
c. the high-energy phosphates stored in muscle cells
Explanation:
Phosphocreatine (PC) or creatine phosphate is a compound rich in energy. It has energy stored in it which can be used to phosphorylate ADP into ATP. The phosphocreatine is stored in muscle cells when muscles are not working. The produced ATP serves as an energy source for muscle contraction. The creatine produced during ATP production is phosphorylated again into PC using ATP when muscles are resting.
