"the factors that mainly affect in the formation of magma can be summarized into three: temperature, pressure, and composition"
I hope this helps =^._.^=
Answer:
The mass of O₂ that will be needed to burn 36.1 g B₂H₆ is 125.29 g.
Answer : The partial pressure of 
and 
are, 84 torr and 778 torr respectively.
Explanation : Given,
Mass of = 15.0 g
Mass of = 22.6 g
Molar mass of = 197.4 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
and,
Now we have to calculate the mole fraction of and .
and,
Now we have to partial pressure of and .
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas
= mole fraction of gas
and,
Therefore, the partial pressure of and are, 84 torr and 778 torr respectively.
Below are the choices that can be found from other sources:
<span>A) elements
B) ions
C) molecules
D) neutrons
the answer is ions.
</span>A Star<span> and hence our Sun, is an almost entirely ionized ball of </span>plasma<span>, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the </span>plasma<span> produces strong magnetic fields and corresponding electric currents.</span>
