Answer:
Explanation:
The strong bases have following properties:
1. In solution, strong bases ionize fully.
2. On dissolving the strong bases in water they produce all hydroxide ion which they have.
3. For strong bases the value of equilibrium constant (Kb ) is large.
4. In general the strong base ionizes completely means concentration of ions are greater means conductivity also greater.
5. For strong bases the value of equilibrium constant (Kb) is large, thus the value of dG0 is very large negative number.
C is the answer the moon has less mass than earth
Answer:
158 L.
Explanation:
What is given?
Pressure (P) = 1 atm.
Temperature (T) = 112 °C + 273 = 385 K.
Mass of methane CH4 (g) = 80.0 g.
Molar mass of methane CH4 = 16 g/mol.
R constant = 0.0821 L*atm/mol*K.
What do we need? Volume (V).
Step-by-step solution:
To solve this problem, we have to use ideal gas law: the ideal gas law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas. The formula is:

Where P is pressure, V is volume, n is the number of moles, R is the constant and T is temperature.
So, let's find the number of moles that are in 80.0 g of methane using its molar mass. This conversion is:

So, in this case, n=5.
Now, let's solve for 'V' and replace the given values in the ideal gas law equation:

The volume would be 158 L.
