Magnesium is more metallic than chlorine because elements with metallic character readily lose electrons. Magnesium has an ionic charge of +2, ie. it will lose 2 electrons if possible. Chlorine has an ionic charge of -1, means that it will gain 1 electron if possible.
Answer:
NaOH is the limiting reactant.
Explanation:
Hello there!
In this case, since the reaction taking place between sodium hydroxide and chlorine has is:
Which must be balanced according to the law of conservation of mass:
Whereas there is a 2:1 mole ratio of NaOH to Cl2, which means that the moles of the former that are consumed by 0.85 moles of the latter are:
Therefore, since we just have 1.23 moles out of 1.70 moles of NaOH, we infer this is the limiting reactant.

The answer is astronomy. There is no ÓLOGY´ at the end of it.
This would be c as for the amswer
Answer:
1. electrical conductor
2. orbit
3. potential energy
4. magnetic field
5. net force
6. B; repulsion
7. A; copper
8. B; there is no gravitational attraction between you and the cup, but Earth's gravity is stronger, so Earth's gravity pulls the cup down
9. A; the net force is acting in an upward direction
10. A; position 1
11. A; the gravitational force between two objects depends on their masses
12. C; the chemical potential energy of the spring is greatest at position 4
13. C; hand-held compass
14. C; a person skiing down a hill
15. A; the ions will repel each other
16. A; position A
17. three properties of magnets are attraction because they attract certain materials, repulsion because magnetic poles repel, and directive because a magnet that is freely suspended will always point in a north-south direction.
18. to increase the strength of an electromagnet you can either increase the strength current or increase the number of windings.
i hope this helps :)
