A compound is found to contain 58.80 % xenon, 7.166 % oxygen, and 34.04 % fluorine by mass. what is the empirical formula for th
marissa [1.9K]
To make it easier, assume that we have a total of 100 g of a compound. Hence, we have 58.80g of xenon, 7.166g of oxygen, and 34.04g of fluorine. 
Know we will convert each of these masses to moles by using the atomic masses:

58.8/131.3 = 0.45 mole of Xe
7.166/16 = 0.45 mole of O
34.04/19 = 1.79 mole of F

Now, we will divide all the mole numbers by the smallest among them and get the number of atoms in the compound:

Xe = 0.45/0.45 = 1
O = 045/0.45 = 1
F = 1.79/0.45 = 3.98 = 4

So, the empirical formula of the compound XeOF₄

Mademuasel [1]

We know that C has a formal charge of +4 while each O element has a formal charge of -2, therefore the formal charge of X is:

X + 2 – 2 * 3 = 0

X + 2 – 6 = 0

X = 4

<span>So X has a group number of 4.</span>

Paha777 [63]

Answer:

D BIOMASS ENERGY

Explanation:

Most biomass requires arable land to develop. This means

that land used for biofuel crops such as corn and soybeans

are unavailable to grow food or provide natural habitats.

Forested areas that have matured for decades (so-called

“old-growth forests”) are able to sequester more carbon

than newly planted areas.
