<u>Answer:</u> The chemical formula is 
<u>Explanation:</u>
Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.
The ionization energy equation for the given values follow:
From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.
Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.
This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.
Hence, the ion formed will be 
Sulfite ion is a polyatomic ion having a chemical formula of 
An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of
Hence, the chemical formula is
Answer: Francesco Redis Experiment part 1 : The maggots were not observed in setup B and setup C because the jars were covered.
part 2 : He discovered that maggots appeared on the meat in the control jar, the jar left open. No maggots appeared in the jar covered with gauze.
Pasteur Experiment
part 1:In the pastures Experiment the microorganisms come from the air.
part 2:Louis Pasteur's pasteurization experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself.
Explanation:
What we want to measure is the taste of coffee.
The following were kept constant during the experimental investigation:
The type of coffee,
The type of percolator,
The same amount and type of water,
The same perking time,
The same electrical sources.
Because these items were kept constant, they are not expected to influence the outcome of the experimental investigation.
Define:
y = the metric used to measure the taste of coffee
x = amount of coffee grounds used for the taste experiment.
Therefore the relationship that arises from the experiment is
y = y(x).
Because x is controllable and is varied during the experiment, it is the independent variable.
Because the measured value of y depends on x, therefore y is the dependent variable.
Answer:
The taste of coffee is the dependent variable.
The amount of coffee grounds used is the independent variable.
