the oxidation states of the elements before and after the reaction is;
Pb oxidation state changes from 0 to +2
SO₄²⁻ ion there's no change in the oxidation state during the reaction
Au oxidation state changes from +3 to 0
reduction reactions are when there's a decrease in the oxidation state of the species
oxidation reactions are when theres an increase in the oxidation state of the species
the element where there's a decrease in oxidation state is Au.
Therefore Au gets reduced.
answer is B) Au
The base peak in the mass spectrum of 3-methylpentane has the most plausible value at m/z=57. Hydrocarbons often undergo mass spectroscopic fragmentation at a branch.
<h3>What does the mass spectrometry Mz value mean?</h3>
The horizontal axis in a mass spectrum is stated in units of mass divided by charge number, or m/z. With GCMS, z is usually always 1, hence the mass is frequently determined by the m/z value.
<h3>What is the M Z of the base peak?</h3>
The base peak of the spectrum is defined as the peak with the arbitrary intensity value of 100. The molecular ion, which has a peak at m/z=72, is what determines the molecule's molecular mass.

To solve this problem, let us first understand what does
mega meters mean. Now by definition, mega means a factor of one million which
is a unit prefix in Metric Systems of units. It is denoted by the unit symbol
M.
So for example if we have a mega of something, it means a
million of something. So in this case, if we have 1 mega meter, what it means
is 1 million meter, which is written as:
1 mega meter = 1,000,000 meter
To show the decimal points:
1.0 mega meter = 1,000,000.0 meter
So we see that the decimal point move 6 zeroes to the
right, therefore the direction is to the right.
Answer:
<span>6 places to the right</span>
