A compound's molecular formula must always be different than the compound's empirical formula. TRUE FALSE
Juli2301 [7.4K]

Answer: False

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Example: CH_4 has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.

C_2H_2 has molecular formula of C_2H_2 but CH as the empirical formula.

Which of the following sentences describes oxygen at room temperature? (check all that apply)
Degger [83]

At room temperature, O2 is in gaseous state.

a gas has no definite volume or definite shape. It occupies volume of container and attains shape of container only.

Thus

It has no definite volume and takes the shape of its container.

Its particles move fast enough to overcome the attraction between them.: the gas molecules have minimum intermolecular interactions and have high kinetic energy.

It has more energy than it would at a cooler temperature: the kinetic energy of gas molecules increases with increase in temperature. Thus the energy increases with temperature and decreases with decrease in temperature.
