<span>Oxidation is the loss of electrons and corresponds to an increase in oxidation state. A reduction is the gain of electrons and corresponds to a decrease in oxidation state. Balancing redox reactions can be more complicated than balancing other types of reactions because both the mass and charge must be balanced. Redox reactions occurring in aqueous solutions can be balanced by using a special procedure called the half-reaction method of balancing. In this procedure, the overall equation is broken down into two half-reactions: one for oxidation and the other for reduction. The half-reactions are balanced individually and then added together so that the number of electrons generated in the oxidation half-reaction is the same as the number of electrons consumed in the reduction half-reaction.</span>
Explanation:
For the given reaction
Now, expression for half-life of a second order reaction is as follows.
....... (1)
Second half life of this reaction will be . So, expression for this will be as follows.
= ...(2)
where is the final concentration that is, here and is the initial concentration.
Hence, putting these values into equation (2) formula as follows.
=
= ...... (3)
Now, dividing equation (3) by equation (1) as follows.
=
= 3
or, = 3
Thus, we can conclude that one would expect the second half-life of this reaction to be three times the first half-life of this reaction.
The empirical formula<span> of a chemical compound is the simplest positive integer ratio of atoms present in a compound. Therefore, the correct answer from the choices is the last option. </span><span>C7H14 and C10H20 have the same empirical formula which is CH2. Hope this answers the question.</span>
For each element, a square on the standard periodic table will contain:
The Atomic Number (the integer at the top, which represents the number of protons in the atoms of that element)
The Chemical Symbol of the element (the one or two letter symbol, such as C for Carbon, Mg for magnesium)
The Atomic Mass of the element (the average mass of all naturally occurring isotopes of that element. It's often a decimal number because it's an average, even though it represents the number of protons and neutrons in the atom)Usually, the element's common name is listed, but not all charts do this.
