2). H2S and SO2 as follows,(8pt) H2S + SO2 >S + H2O

In a particular experiment, 7.95 g of sulfur is produced by the reaction of 7.5 g of H2S with 12.75 g of SO2.

What is the % yield of sulfur?

75.7 % yield

Explanation:

The balanced chemical equation is:

According to stoichiometry :

68.2 g of will require = 64 g of

Thus 7.5 g of will require = of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

As 68.2 g of give = 96 g of

Thus 7.5 g of give =  of

% yield=

Thus 75.7 % yield is there.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
