Answer: C. Acts as energy reserve in muscle tissue.
Explanation:
Creatine Phosphate is a high energy compound that can be found in muscle tissue.
It serves as an extra energy storage, since the normal metabolism cannot supply the high energy requirement of a muscle at work.
Creatine Phosphate is quickly transfered to ADP, for the production of ATP needed for muscle contraction.

Answer : The density of air in and is, and respectively.
Explanation :
where,
P = pressure of air = 1 atm
V = volume of air
T = temperature of air = 297 K
The conversion used for the temperature from Fahrenheit to degree Celsius is:
The conversion used for the temperature from degree Celsius to Kelvin is:
n = number of moles
m = mass of air
M = average molar mass of air = 28.97 g/mole
= density of air = ?
R = gas constant = 0.0821 L.atm/mol.K
Now put all the given values in the above formula, we get:
Now we have to calculate density in .
Conversion used :
So,
The density of air in is,
Now we have to calculate density in .
Conversion used :
So,
The density of air in is,
Answer:
To convert from mols to grams, multiply the number by the total molar mass of the compound.
To find the approximate molar mass of a compound, add up the molar masses of each element in the compound, making sure to multiply by the subscripts.
<u>#2 for example:</u>
First, find the molar mass of NaCl.
Molar mass of Na= 22.990g (refer to a periodic table or look it up)
Molar mass of Cl= 35.45g
22.990g + 35.45g= 58.44g
Next, convert from mols to g.
2.19 mol x 58.44g= 127.98g NaCl
To convert from grams to mols, do the same thing as mols to grams except DIVIDE instead of multiply.
<u>#3 for example:</u>
NaC2H3O2
Na= 22.99g
C2= 12.011 x 2 => 24.022g (multiply molar mass of C by 2 since there are 2 carbons)
Do this for the rest of the elements in the compound and add them up. The total molar mass should be approximately 82.0343g.
Next, convert from g to mol.
14.68g/82.0343g≈ 0.179 mol
