Answer:In regards to writing the formula, we know that magnesium has a charge of 1+ and sulfate, SO4, has a charge of 1-. Sulfate is a polyatomic ion so the charge of the whole thing is (SO4)1-. When you combine them you end up with MgSO4 and the "heptahydrate" is seven water molecules.
Explanation:
Convection
Explanation:
Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.
There are different types of heat transfer:
- Conduction
- Convection
- Radiation
Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.
Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.
Radiation is heat transfer using electromagnetism and does not involve molecules of the medium
The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

Phase is not determined by the number of molecules, as a substance with any number of molecules can be either solid, liquid, or gas.
Arrangement of molecules and molecular structure matter, since solids are closely packed together, gases are not, and liquids are in between. Intermolecular forces are also stronger for solids and liquids than they are for gases.
Answer:

Explanation:
just divide. hope this helps!
In determining the boiling point
of solutions, always take note of the number of ions that will dissociate in
the solution. It does not depend on the nature of the substance. The greater
the number of ions dissociated, the greater is the boiling point of the solution.
