the molecular formula of an unknown hydrocarbon
$43\ \mathrm g$ of carbon for $7.2\ \mathrm g$ hydrogen.
Molar mass of carbon is $12\ \mathrm{g/mol}$ and that of hydrogen is $1\ \mathrm{g/mol}$.
Hence there are $\frac{43\ \mathrm g}{12\ \mathrm{g/ …

Applying Avagadro's law: the relationship between moles and volume of a gas
You are correct in your approach and answer. Assuming the gas to be ideal, one can apply Avogadro's Law which states that for an ideal gas $V \propto n$.
This implies $V_1/n_1 = V_2/n_2$.
Using the …

Is F2 two fluoride ions or just one?
$\ce{F2}$ will produce $2\space \ce{F-}$ ions.
You can write the balanced half cell reactions as follows:
$\ce{F2 + 2e- ->2F-}$
$\ce{Li -> Li+ + e-}$
Multiply the second equation by 2 to get $\ce …
