Break down the table into smaller sections. Memories period by period or if you like by group (like halogens or noble gases).
Just say the elements in order everyday 1-10 then when you get those 11-20 and continued.
Answer:
In order to determine unequivocally which of the peaks represent Aldrin, I would run the pure sample through the chromatography equipment.
Explanation:
Gas chromatography is a technique that separates molecules based on their volatility and interaction with both the stationary phase.
The peaks on the chromatogram show how long a substance took to leave the column. Since each different substance substance will leave the column at a different time, each peak can be attributed to a substance.
Therefore, to know which of the 6 peaks represent Aldrin, it is necessary to run the pure Aldrin in the chromatography equipment and see the time of the peak. Then you just need to compare both chromatograms and indentify Aldrin.
Answer:
they both have seven electrons in the outer shell
they are all just one electron shy of having full shells
The mass of MgCl₂ produced is 5.685 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter of a physical body.
The reaction is
Mg + 2HCl → MgCl₂ + H₂
2 mole of HCl
(2 × 36.458) = 72.8 g
1 moles of MgCl₂
(1 × 95.21 g) = 95.21 g
1 g Mg will produce = 
4.67 mol Mg will produce
Thus, the mass of MgCl₂ produced is 5.685 grams.
