We see from the chemical formula itself that there is 1
mole of F2 for every 1 mole of CaF2, hence the number of moles of CaF2 is also:
moles CaF2 = 1.23 moles
The molar mass of CaF2 is 78.07 g/mol, so the mass is:
mass CaF2 = 78.07 g / mol * 1.23 mol
<span>mass CaF2 = 96.03 grams</span>
<span>Determine the concentration of the ion solvent in solution (moles of solvent/Liter of solution) and then multiply by Avogadro's Number. That will give you the number of ionic atoms of a particular type in that solution.</span>
Answer:
the stream contains more water and moves faster
Explanation:
Answer:
In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.
Explanation:
SO2 is a polar molecule because Oxygen gains more electrons making one side more negative than the other.
