Answer:
Magma becomes rock after the heating process has settled.
Explanation:
Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.
Answer:
What does that even mean?
Explanation:
As the intermolecular forces get weaker, the amount dissolved decreases. Ammonia can form hydrogen bonds with water thus allowing it to be more soluble. CO2 and O2 can only react through London forces, but since CO2 has a higher molecular mass, more electrons, it will have a larger in magnitude temporary dipole moment. This results in the CO2 being more soluble in water than O2.
The overall trend in solubility is NH3>CO2>O2

Answer:
7.92gml-1
Explanation:
water=25.20ml
water+iron=25.92ml
iron=5.7g
P=mass/volume (formula of density)
mass=5.7g
volume=25.92-25.20
=0.72ml
p=5.7/0.72
=7.92gml-1
