Select the correct empirical formula for each molecular formula given.
Sauron [17]

Answer:

CH₂O

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number.

Molecular formula:

Molecular formula shows the actual whole number ratio of elements present in compound.

Given molecular formula: C₆H₁₂O₆

Empirical formula = CH₂O

In molecular formula six moles of carbon six moles of oxygen and 12 moles of hydrogen are present.

To get the smallest whole number we divide the each number by 6 and we get CH₂O which is empirical formula of C₆H₁₂O₆.

A hardware salesman measures the mass of a box containing
sattari [20]

Step 1

<u>find the mass of a single washer</u>

Divide the total mass by the number of washers

\frac{0.4168}{1000} =0.0004168\ Kg

0.0004168kg=4.168*10^{-4} kg

Step 2

<u>Convert kg to mg</u>

we know that

1 kg=1*10^{6} mg

so

4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg

therefore

<u>the answer is</u>

416.8 mg

What shape would a molecule of carbon tetrachloride have?
Elden [556K]

Answer:

Tetrahedral

Explanation:

For the repulsion of the free electron pair theory, the shape of a molecule will be to repel the bonds and the free electrons on the central atom. In a molecule of carbon tetrachloride, the central atom (C) has no free electrons, so, the shape that repels better the charge is tetrahedral, as shown below.
