Answer:

2NaBr + CaF₂ ⟶ 2NaF + CaBr₂

Explanation:

Put a 1 in front of the most complicated-looking formula (CaF₂?):

                       NaBr + 1CaF₂ ⟶ NaF + CaBr₂

Balance Ca:    NaBr + 1CaF₂ ⟶ NaF + 1CaBr₂

Balance F:      NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂

Balance Na: 2NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂

————————————————————

<em>Check</em>

<u>Atom</u>  <u>On the left</u>  <u>On the right </u>

  Na             2                   2

  Br              2                   2

  Ca             1                     1

  F               2                    2

The balanced equation is

2NaBr + CaF₂ ⟶ 2NaF + CaBr₂

A sample of a compound contains 3.21 g of sulfur and 11.4 g of fluorine. Which of the following represents the empirical formula
Sergeeva-Olga [200]

Answer:

The empirical formula is SF6 (option E)

Explanation:

Step 1: Data given

Mass of sulfur = 3.21 grams

Mass of fluorine = 11.4 grams

Molar mass sulfur = 32.065 g/mol

Molar mass fluorine = 19.00 g/mol

Step 2: Calculate moles

Moles = mass /molar mass

Moles sulfur = 3.21 grams / 32.065 g/mol

Moles sulfur = 0.100 moles

Moles fluorine = 11.4 grams / 19.00 g/mol

Moles fluorine = 0.600 moles

Step 3: Calculate mol ratio

We divide by the smallest amount of moles

S: 0.100 / 0.100 = 1

F : 0.600 / 0.100 = 6

The empirical formula is SF6 (option E)
