Hydrogine peroxide
Maintains level of hydrogen sulfate inbalance
5= Elemental hydrogen, nitrogen, oxygen, fluorine and chlorine are all gases at room temperature,
Answer is: the osmotic pressure of aqueous solution of sucrose is 6.032 atm.<span>
c(C</span>₁₂H₂₂O₁₁) = 0.237 mol/L; concentration of solution.
T(C₁₂H₂₂O₁₁) = 37°C = 310.15 K; temperature in Kelvins.
R = 0.08206 L·atm/mol·K; universal gas constant.
π = c(C₁₂H₂₂O₁₁) · T(C₁₂H₂₂O₁₁) · R.
π = 0.237 mol/L · 310.15 K · 0.08206 L·atm/mol·K.
π = 6.032 atm · 101.325 kPa/atm = 611.2 kPa
Using the formula PV=nRT (p is pressure of gas, v is volume of gas, n is amount of particles, r is the gas constant and t is absolute temperature of the gas), an increase in number of particles will result to an increase in pressure as long as the other variables remain constant.

Explanation:
Well, kinetic energy is expressed through the equation:
KE
=
1
2
m
v
2
m
is the mass of the object in kilograms
v
is the velocity of the object in meters per second
So, we plug in the values, which are
m
=
0.02
kg
v
=
300
m/s
And we get,
