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.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point)
iris [78.8K]

The true statement about the balanced equations for nuclear and chemical changes is; both are balanced according to the total mass before and after the change.

A basic law in science is called the law of conservation of mass. Its general statement is that mass can neither be created nor destroyed.

Both in chemical and nuclear changes, mass is involved and in both cases, the law of conservation of mass strictly applies.

This means that for both chemical and nuclear changes; total mass before reaction must be equal to total mass after reaction.

Hence, both reactions are balanced according to the total mass before and after the change.

The drugs Prilosec and Nexium both contain the same active ingredient. Nexium contains a single enantiomer, but Prilosec is a ra
Softa [21]

Answer:

both drugs will be equally effective

Explanation:

A racemic mixture is a substance that contains a 50/50 mixture of the (+) and (-) enantiomers of an optically active compound.

It is important to note that even if a drug occurs as a racemic mixture, only the biologically active enantiomer will interact with the substrate on which the drug acts. The other enantiomer present is just irrelevant. Similarly, its presence does not affect the biological activity of the active enantiomer.

Hence, both Prilosec and Nexium are both equally effective.
