Answer:
101.2%
Explanation:
Given:
Theoretical yield of the precipitate = 0.914 g
Actual yield of the precipitate = 0.925 g
Now, the percent yield is given as a ratio of actual yield by theoretical yield expressed as a percentage.
Framing in equation form, we have:
Now, plug in 0.925 g for actual yield, 0.914 g for theoretical yield and solve for % yield. This gives,
Therefore, the percent yield is 101.2%.
If the forces are equal and in opposite directions, the net force will equal zero.
Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.
<em>F = ma </em>
The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
Answer:
a. changes with temperature.
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the equilibrium constant in terms of the Gibbs free energy of reaction and the temperature of the system:
It is possible to figure out that the equilibrium constant varies as temperature does, not only on the aforementioned definition, but also in the Gibbs free energy as it is also temperature-dependent. Therefore, the appropriate answer is a. changes with temperature.
Best regards!
