Nitrogen. air consists 78% of nitrogen gas
Answer:
237.5 K.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 5.2 atm).
V is the volume of the gas in L (V = 15.0 L).
n is the no. of moles of the gas in mol (n = 4.0 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = ??? K).
∴ T = PV/nR = (5.2 atm)(15.0 L)/(4.0 mol)(0.0821 L.atm/mol.K) = 237.5 K.
80ºF.
Explanation:
At a temperature of 80ºF, the milk has the highest thermal energy.
The thermal energy in a body increases as the temperature of the body increases.
To increase the temperature of a body, heat is a supplied to it or work is done on it.
- Heat is a form of thermal energy.
- As the heat increases, the particles of the milk gains more kinetic energy.
- This forces them to move more faster.
- A body with a higher temperature has more thermal energy.

Answer: 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the 
is given as:
When the solubility of is S moles/liter, then the solubility of 
will be S moles/liter and solubility of 
will be 2S moles/liter.
By stoichiometry of the reaction:
1 mole of gives 1 mole of 
and 2 moles of
