Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Jokes from Savannah~
A man goes to the doctor, concerned about his wife’s hearing. The doctor says, “Stand behind her and say something and tell me how close you are when she hears you.”
The man goes home, sees his wife in the kitchen, cutting carrots on the countertop. About 15 feet away he says, “Honey, what’s for dinner?” Nothing. He gets halfway to her and repeats the same question. Nothing. Very concerned, he gets right behind her and asks again “What’s for dinner?”
She turns around and says “For the THIRD time, beef stew!”

The two chemical formulas which will correctly complete the table for lithium fluoride are: A. HF, LiOH.
<h3>What is a chemical reaction?</h3>
A chemical reaction can be defined as a chemical process that involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, in order to produce a new chemical compound while new bonds are formed.
This ultimately implies that, chemical bonds between atoms of a chemical element are broken and then new bonds are formed in all chemical reactions.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction can be defined as a type of chemical reaction between an acid and a base, which typically leads to the formation of an ionic compound (salt) and water as end products as shown below:
LiOH(aq) + HF(aq) → LiF(s) + H₂O(l)
In this context, we can infer and logically deduce that the two chemical formulas which will correctly complete the table for lithium fluoride are HF and LiOH.

Answer:
D). She should use a bar graph. The bottom of each bar should be labeled with the category of garbage. The vertical side should have a scale and be labeled "kilograms per year."
Explanation:
Bar graphs are characterized as the graphic tool which are primarily employed to establish comparison between various groups or to observe the changes occurred over time.
As per the question, the environmental scientist must opt for the 'bar graph' as it will assist her in displaying the data of various categories(paper, yard waste, metals, etc.) through bars on the x-axis while the vertical side or y-axis would show 'kilograms per year' which will display the differences in their amounts. Thus, <u>option D</u> is the correct answer.
