Can anyone Please do this for me???I am trying to help my son with his Chemistry and I don't understand it. I have read the text

book and researched it on the internet, but I still can't figure it out and my son doesn't understand it either. I just need someone to explain to me what to do, not do it for him. This way he can still do the work. Thank You!
Researching Elements in the Periodic Table:
Directions
Overview:
The periodic table includes groups of elements that have unique and useful capabilities. Such capabilities are due to the properties of the elements—such as ionization energy, atomic radius, and boiling point.
For this assignment, you will choose one of the groups of representative elements 1A–7A in the periodic table to research, as well as one element within that group to research.
Use your textbook and the Internet to perform your research. Note: Your textbook contains information about elemental groups in the periodic table in Appendices A and B.
Procedure:
1. For each element in the group that you have chosen, organize the following information in a data table in Microsoft Excel: • Element name
• Element symbol
• Atomic number
• Atomic mass
• Melting point
• Boiling point
• Electronegativity value
• Atomic radius
• Ionic radius
• First ionization energy


2. Use Microsoft Excel to create a line graph of ionic radius (y-axis) versus atomic number (x-axis). Save your completed graph to your Desktop so that you can submit the file to your teacher for grading.

3. Use Microsoft Excel to create a line graph of first ionization energy (y-axis) versus atomic number (x-axis). Save your completed graph to your Desktop so that you can submit the file to your teacher for grading.

4. Type a one-to-two paragraph analysis of your graphs that addresses the following: • What is the relationship between the atomic numbers and ionic radii of the elements in the group?
• What is the relationship between atomic numbers and first ionization energies?
• Why do these relationships exist? Propose an explanation for each of these relationships.
• Are these relationships consistent with the periodic trends that you have been studying?


5. Choose one element from within the group that you have selected. Write a one-to-two paragraph description of the element that addresses the following: • What was the date of the element’s discovery?
• Which scientist or scientists discovered the element?
• Where was the element discovered?
• How was it discovered?
• Describe any unique properties of the element.
• Describe any uses or products that have developed from the discovery of the element.

Number 1 do a data table on paper and do as it was said, then go into Microsoft Excel and put your chart in. For 2 make a line graph(as stated) and do what it tells you.For 3 do as said with the line graph or whatever it should look somewhat like a math chart(the coordinate plane) and do as said. For number 4 help him/her study the charts and analyze the difference between the two. And for number 5 make him/her choose one element and research and write down the questions.

PLS HELP Students in a chemistry class added 5 g of Zinc (Zn) to 50 g of hydrochloric acid (HCl). A chemical reaction occurred t
Vitek1552 [10]

Answer: In simplest case mass of reactants is same as mass of products.

Without thinking this question deeper, mass of ZnCl2 would be 49, but..

Explanation: Reaction should be  Zn + 2 HCl ⇒ ZnCl2 + H2

Amount of zinc is  5 g / 65,38 g/mol = 0,076476 mol and amount

of Hydrogen Chloride is 50 g / 36.458 g/mol = 1,371 mol.

Althought HCl is needed 0.152 moles, zinc is an limiting reactant.

So it is possible to produce only 0.076476 mol Hydrogen and its mass

is 0.154 g.  Mass of ZnCl2 would be 0.076476 mol · (65.38 + 2·35.45) =

 10.42 g
