The answer has to be either CO2 or mg. But i am not sure which one
0.447 is the mole fraction of Nitrogen in this mixture.
mole fraction of nitrogen= moles of nitrogen/total moles
mole fraction of nitrogen=0.85/1.90
mole fraction of nitrogen=0.447
The product of the moles of a component and the total moles of the solution yields a mole fraction, which is a unit of concentration measurement. Because it is a ratio, mole fraction is a unitless statement. The sum of the components of the mole fraction of a solution is one. In a mixture of 1 mol benzene, 2 mol carbon tetrachloride, and 7 mol acetone, the mole fraction of the acetone is 0.7. This is computed by dividing the sum of the moles of acetone in the solution by the total number of moles of the solution's constituents:

Answer:
C. results when an alkaline-earth metal loses one of its outermost electrons
Explanation:
An ion can be said to result when an alkaline - earth metal loses one of its outermost electrons.
Ions are charged substances that takes part in chemical reaction.
- An an atom is neutral substance that is a component of an element.
- An ion is charged substance.
- In an ion, the number protons and electrons are unbalanced.
- The number of protons in an atom are the positively charged particles.
- The number of electrons are the negatively charged particles.
When there is an inequality between the number of protons and electrons within an atom, an ion forms.
