Explanation:
you need to leave some water to stop dehydration of substance
Answer:
At a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
Explanation:
In its pure state, the detergent has a 100% concentration. Thus, knowing that the product of the concentration by volume must be constant, we can do:
C1V1 = C2V2
Where C is the concentration, V is the volume, 1 is the pure detergent, and 2 the solution. So, let's find the volume of pure detergent needed to prepare 500 mL of the solution:
100*V1 = 0.2*500
100V1 = 100
V1 = 1 mL
Thus, at a 500 mL volumetric ballon, it will be added a little of distilled water, then 1 mL of the pure detergent, and then it will be added water until the meniscus. The solution will be agitated by inverting the flask until it's homogeneous.
Answer:
Explanation:
The Key results in the Lab guide are results that justify the reasons to either accept or reject a hypothesis.
To summarize data related to findings in an experiments we make use of diagrams that shows the relationship between the different data.
Although the Lab guide in the question is missing a general answer within the scope of your question is provided above
Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result. while
The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )
Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.
Explanation:
It is known that relation between Gibb's free energy and equilibrium or reaction quotient is as follows.
..... (1)
At equilibrium, = 0. Also, Q = K this means that reaction is at equilibrium.
Therefore, formula in equation (1) will become as follows.
....... (2)
It is known that for a sparingly soluble salt, K =
Thus, equation (2) will become as follows.
....... (3)
So, when value of increases then there will be decrease in the value of according to equation (3).
Hence, we can conclude that the calculated value of would be too big.
