Answer:
magnesium has a greater charge, there will be greater attraction between delocalised electrons and the positively charged ion.
Explanation:
I did this once and got it right I hope you get it right too
<u>We are given:</u>
Mass of NaCl in the given solution = 22.3 grams
Volume of the given solution = 2 L
<u></u>
<u>Number of Moles of NaCl:</u>
We know that the number of moles = Given mass / Molar mass
Number of moles = 22.3 / 58.44 = 0.382 moles
<u></u>
<u>Molarity of NaCl in the Given solution:</u>
We know that Molarity of a solution = Moles of Solute / Volume of Solution(in L)
Molarity = 0.382 / 2
Molarity = 0.191 M

In order to determine if the ion is positively charged or negatively charged
Answer:
D
Explanation:
The sample must contain impurity that is lower in atomic mass to sodium and since potassium has higher atomic mass to sodium, the answer is the sample contains NaCl and LiCl. We are sure already that the sample is not pure which rules out option a and option b contains sodium iodide which cannot contribute to the increase in chlorine
Answer: Studying stem cells can help scientists understand more about how the body works and how disease develops and affects the body so yes
Explanation: Studying stem cells can help scientists understand more about how the body works and how disease develops and affects the body. Working with stem cells may help researchers better understand different diseases and conditions, and find new treatments.
