Explanation:
The orbital for fluorine is 1s 2s 2p. All of the boxes should be filled COMPLETELY until you can't no more. How do you know if you can't anymore? By the <u>atomic number</u> of the element. The atomic number for fluorine is 9. So, you keep adding arrows starting from the first box all the way to the last until you have reached the atomic number, in this case, 9.
Answer:
Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.
<h3>What is meant by a mass fraction?</h3>
Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.
The formula for a mass fraction (w) is given as,
Mass fraction (w) = mass ÷ total mass
Given,
Mass of chlorine = 35.453 grams per mole
The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole
Substituting and solving the values above as
w = mass of chlorine ÷ total mass of calcium chlorate
w = 35.453 ÷ 206.98
w = 0.171
Therefore, the mass fraction of Cl in calcium chlorate is 0.171.

C. Earth's gravitational force is stronger than the Moon's.
Since Earth has a far larger mass than the Moon, its gravitational force is also higher.
