What will happen if pressure is increased on the system?
andrew11 [14]
It depends on the system if there are more moles of gas on the left and you increase the pressure the yield of a product will increase as the equilibrium moves to the side with the fewest gas molecules

if the right hand side has more moles of gas and you increase the pressure the yield will decrease as the equilibrium shifts to the left hand side where there are more gas moles 

hope that helps

The reaction of silver metal and dilute nitric acid proceeds according to the equation above. If 0.10 mole of powdered silver is
Crazy boy [7]

Answer:

The answer to your question is: 0.015 mole of NO

Explanation:

Data

Silver = Ag = 0.1 mole

Nitric acid = HNO3 = 10 ml   6 M

Balanced reaction

                     3Ag    +  4HNO₃    ⇒     3AgNO₃   +    NO    +     2H₂O

# moles of HNO₃ = 6(0.01) = 0.06

Limiting reactant   HNO₃  because for the amount of silver given

                              the reaction  needs 0.133 moles of acid, and  there

                             are only 0.06

                    4 mol of HNO₃   -------------------  1 mol of NO

                   0.06 mol of Ag  ------------------    x

                   x = (0.06 x 1) / 4

                   x = 0.015 mol

If 25.8 grams of BaO dissolve in enough water to make a 212-gram solution, what is the percent by mass of the solution?
Maksim231197 [3]
The answer is A. 12.2% BaO

Below is the solution as to how the answer was generated:

Let:

25.8g = mass of solute

212g = mass solution

Equation:

% = (mass of solute / mass solution) x 100

Substitute the given values to the equation:

% = (25.8 / 212) x 100

% = 0.122 x 100

= 12.2%
