Answer:

A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds and a type of fat containing a high proportion of fatty acid molecules with at least one double bond, considered to be healthier in the diet than saturated fat.

The reaction of hydrogen sulfide(g) with oxygen(g) to form water(l) and sulfur dioxide(g) proceeds as follows: 2H2S(g) 3O2(g)2H2

Aleks [24]

Answer: The value of $\Delta H$ is 1118 .

Explanation:

To calculate the number of moles, we use the equation:

$\text{Moles of solute}=\frac{\text{given mass}}{\text{molar mass}}$

$\text{Moles of} H_2S}=\frac{9.82g}{34.1g/mol}=0.288mol$

The balanced chemical reaction is:

$2H_2S(g)+3O_2(g)\rightarrow 2H_2O(l)+2SO_2(g)$

Given :

Energy released when 0.288 mole of $H_2S$ is reacted = 161 kJ

Thus Energy released when 2 moles of $H_2S$ is reacted = $\frac{161}{0.288}\times 2=1118kJ$

Thus the value of $\Delta H$ is 1118.
