The atomic mass of carbon is 12.011 g/mol.
The atomic mass of hydrogen is 1.00794 g/mol.
The atomic mass of sulfur is 32.06 g/mol.

This means that the molar mass of $\text{C}_{2}\text{H}_{4}\text{S}$ is

$2(12.011)+4(1.00794)+32.06=60.11376$

Dividing this by the given molar mass, we get $\frac{168}{60.11376} \approx 3$

So, the molecular formula is about $\boxed{\text{C}_{6}\text{H}_{12}\text{S}_{3}}$

Draw all possible structures for a compound with molecular formula C4H8O that exhibits a broad signal between 3200 and 3600 cm-1

MrRissso [65]

Answer:

Cyclic butanol , 1 cyclopropyl methanol, 1-methyl cyclo propan-1-ol.

Explanation:

IR wave-number of O-H bond = $3600 - 3200 cm^{-1}$

The intensity of the signal is broad and strong.

IR wave number of C=C bond = $1680 - 1600 cm^{-1}$

The intensity of the signal is weak.But for the given chemical formula it didn't show any signal in its IR spectrum.This means that no unsaturation is present.

IR wave number of C=O bond = $1780 - 1650 cm^{-1}$

The intensity of the signal is broad and strong.But for the given chemical formula it didn't show any signal in its IR spectrum. This means that no C=O is present in the compound

For the given formula the possible structures wil be:

$C_4H_8O: C_4H_7OH$

As we know from the I.R. data that no unsaturation is present which indicates that the given compound has cyclic structure.

Consider the formation of nitryl fluoride: 2NO2(g)+F2(g)⇌2NO2F(g) The reaction is first order in F2 and second order overall. Wh

Dahasolnce [82]

Answer:

Rate = $k[NO_{2}][F_{2}]$

Explanation:

Two reactants are present in this reaction which are $NO_{2}and F_{2}$
We know overall order of a reaction is summation of individual order with respect to reactants present in rate law equation.
Here, overall order of reaction is 2 including first order with respect to $F_{2}$
So, rate of reaction should also be first order with respect to another reactant i.e. first order with respect to $NO_{2}$
So, rate law: rate = $k[NO_{2}][F_{2}]$
