What does Le Chateliers principle say about upsetting a system at equilibrium

1 answer:

3 0

Le Chatelier principle says, if a restriction is applied to a system in equilibrium, the system adjusts to a new equilibrium that tends to counteract the restriction. When equilibrium is under stress it will shift to relieve that stress.

all concentrations would change.

Question 2 (2 points)

poizon [28]

Answer:

$m_w=439.2g$

Explanation:

Hello!

In this case, since the by-mass percent of a solution is a measure of the mass of the solute over the mass of the solution:

$\%m/m=\frac{m_{solute}}{m_{solution}} *100\%$

As we know the mass of the solution and the by-mass percent, we can compute the mass of glucose in the 480 g of solution:

$m_{solute}=\frac{\%m/m*m_{solution}}{100\%}$

Thus, by plugging in the data, we obtain:

$m_{solute}=\frac{8.5\%*480g}{100\%}=40.8g$

Finally, since the solution is made up of glucose and water, we compute the mass of water as follows:

$m_w=m_{sol}-m_{solute}=480g-40.8g\\\\m_w=439.2g$

Best regards!

How a change in DNA can lead to a change in phenotype. With an example

Gennadij [26K]

Answer:

Variation within genes leads to different genotypes , which can be seen by the individuals having different phenotypes . For example, the dogs above all have different fur colours and fur lengths. Genetic and environmental variation combine together to produce these different phenotypes.
