Answer: As magma cools and crystallizes minerals form is predictable patterns in a process known as '<em>Bowen reaction series'.</em>
Explanation:
The sequence in which minerals crystallize out from the magma is Bowen's reaction series. The top most layer of the magma will crystallize first and slowly successive layers will cool down to form crystals.
The newly formed mineral from the cooling magma reacts again with the remaining magma further to form another series of minerals.
The pressure of the gas is 3.52 atm
<u><em>calculation</em></u>
This is calculated using the Boyle's law formula
that is P1V1= P2V2 where;
P1 = 1.65 atm
V1 =22.8 L
P2 =? atm
V2 = 10.7 L
make P2 the subject of the formula by dividing both side by V2
P2 = P1V1 / V2
P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm
1.A law is an observation; a theory is the explanation of that observation.
2.A theory requires experimentation under various conditions. A law has no such requirements.
3.A theory may become obsolete with time. This is not the case with a law.
4.A theory can be replaced by another better theory; however, this never happens with a law.
5.A theory may be strong or weak according to the amount of evidence available. A law is a universally observable fact.

Boiling point of ethanol is 78.5
of ethanol is
The relationship between boiling point elevation of a solution and molality can be represented as,
Δ
Molality of the solution (m) =
= 0.234 m
Therefore the boiling point of solution will be 73.8
