Answer:
I believe it is 3 and 4. I really hope it is but i am positive :)
The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.
Answer:
The answer to your question is Pressure = 5 atm
Explanation:
Data
Volume 1 = V1 = 0.5 l
Pressure 1 = P1 = 1 atm
Volume 2 = V2 = 0.1 l
Pressure 2 = P2 = x
Formula
To solve this problem use the Boyle's equation
V1P1 = V2P2
Solve for P2
P2 = V1P1/V2
Substitution
P2 = (0.5 x 1) / 0.1
Simplification
P2 = 0.5/0.1
Result
P2 = 5 atm
Answer:
Both B and D are correct.
Explanation:
B + H₂O ⇌ BH⁺ + OH⁻
If you add more products, the position of equilibrium will shift to the left to decrease their concentrations (Le Châtelier's Principle). The concentration of reactants will increase, but the equilibrium concentrations of products will also be higher than they were initially.
A is wrong. The equilibrium constant is a constant. It does not change when you change concentrations.
C is wrong. Per Le Châtelier's Principle, the concentrations must change when you ad a stress to a system at equilibrium.
(This is a poorly-worded question. "They" are probably expecting answer D.)
