Answer:
It's option a) Permeability.
Constitutional isomers<span> are compounds that have the same molecular formula but different connectivity.
To determine whether two molecules are </span>constitutional isomers<span>, just count the number of each atom in both molecules and see how the atoms are arranged.
If both molecules have the same count for </span>all<span> of the different atoms, </span>and<span> the atoms are arranged in different ways (i.e. their </span>connectivity<span> is different), then they will be constitutional isomers.
In this case C2H5Cl will not have any constitutional isomer. Because you can attach the Cl on first carbon or second carbon, both structure will be same. There will only exist one structure. Figure is attached</span>
Hey there!
The independent variable is the factor that is deliberately manipulated in an experiment. The dependent variable is the variable in a relation whose value depends on the value of the independent variable.
Second, hypotheses and predictions are similar in that they are both related to an experiment. However, a hypothesis is an explanation for a phenomena that is testable through an experiment. A prediction is the expected result of an experiment.
An when conducting an experiment, it is always important to present accurate data even if that data does not support your hypothesis. If your data does not support the hypothesis, the experiment was not a waste of time. This data provides you with information regarding what is not happening in a particular phenomenon. Information gained from the experiment can help you to develop new hypotheses to test in the future.
Hope this helped.

Answer : The balanced half-reaction in a basic solution will be,
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Rules for the balanced chemical equation in basic solution are :
First we have to write into the two half-reactions.
Now balance the main atoms in the reaction.
Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion at that side where the less number of hydrogen are present.
Now balance the charge.
- Now balance the oxygen atoms.
- Now balance the hydrogen atoms.
The balanced half-reaction in a basic solution will be,
From the equation, we see that for every 4 moles of pyrite consumed, 11 moles of oxygen are consumed.
So, the answer is (10.5/4)(11) = <u>28.875 mol</u>
