Magnesium combined with chlorine.
How?
- Look at the question .Compound has -1 charge in it .Hence it contains Halogen.
- Looking at the options Option B and C contain Iodine and chlorine i.e halogens .
Now come to metals side.
- Potassium has valency 1(Look the Electronic configuration below)
Hence it will contain +1 charge which is omitted directly .
Now come to option C.
- Magnesium has charge +2(Look at EC below
Hence the compound formed is given by
Hence option C is correct.
Answer:
2?
Explanation:
Well the rocks can be thrown around or just start breaking down. Sorry if I'm not correct
igneous rocks cool very slowly
Explanation:
Large crystals are formed when rocks cool very slowly. This gives time for crystallization nuclei to form and other crystals aggregates round it.
- Large crystals in rocks are typical of intrusive igneous rocks.
- These rocks are formed beneath the earth surface and they usually have big crystals.
- This because they cool slowly and have time for crystal formation.
- Rocks that cools rapidly are extrusive igneous rocks.
- They are usually fine grained and glassy in nature.

I think A is correct:
deltaH=(Enthalpie of reactents)-(Enthalpie of products)=110.525+285.5-393.5=2.525~2.825
Explanation:
A water fall falls and hits the base with force depending on the distance from which it fell.This force is caused by gravity pulling the water molecule as well as some other particles like eroded soil rapidly downwards.
