When magnesium is burned, it reacts with oxygen in air not with the fire. The fire is the energy needed for the reaction to happen. Magnesium reacts with oxygen forming magnesium oxide. The light emitted from the reaction is because the reaction produced a lot of heat.
Answer : The mole fraction of NaCl in a mixture is, 0.360
Explanation : Given,
Moles of = 7.21 mole
Moles of = 9.37 mole
Moles of = 3.42 mole
Now we have to calculate the mole fraction of .
Now put all the given values in this formula, we get:
Therefore, the mole fraction of NaCl in a mixture is, 0.360
When air pressure is low it is Cold
