Acompound that contains only carbon, hydrogen, and oxygen is 48.64% c and 8.16% h by mass. what is the empirical formula of this substance? 84. the most common form

The empirical formula of this substance is:

Explanation:

To find the empirical formula of this substance we need the molecular weight of the elements Carbon, Hydrogen and Oxygen, we can find this information in the periodic table:

- C: 12.01 g/mol

- H: 1.00 g/mol

- O: 15.99 g/mol

With the information in this exercise we can suppose in 100 g of the substance we have:

C: 48.64 g

H: 8.16 g

O: 43.2 g (100 g - 48.64g - 8.16g= 43.2 g)

Now, we need to divide these grams by the molecular weight:

We need to divide these results by the minor result, in this case O=2.70 mol

We need to find integer numbers to find the empirical formula, for this reason we multiply by 2:

This numbers are very close to integer numbers, so we can find the empirical formula as  subscripts in the chemical formula:

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
