Various members of a class of compounds, alkenes, react with hydrogen to produce a corresponding alkane. termed hydrogenation, this type of reaction is used to produce products such as margarine. a typical hydrogenation reaction is c10h20() + h2(g) → c10h22(5) decene decane how much decane can be produced in a reaction of excess decene with 2.45 g hydrogen? give your answer in scientific notation. o *10 g decane

The mass of decane produced is

Explanation:

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

      ......(1)

Mass of hydrogen gas = 2.45 g

Molar mass of hydrogen gas = 2 g/mol

Putting values in equation 1:, we get:

The chemical equation for the hydrogenation of decene follows:

As, decene is present in excess. So, it is considered as an excess reagent.

Thus, hydrogen gas is a limiting reagent because it limits the formation of products.

By Stoichiometry of the reaction:

1 mole of hydrogen gas produces 1 mole of decane.

So, 1.225 moles of hydrogen gas will produce = of decane

Now, calculating the mass of decane by using equation 1, we get:

Moles of decane = 1.225 mol

Molar mass of decane = 142.30 g/mol

Putting values in equation 1, we get:

Hence, the mass of decane produced is

the ratio of the conjugate base to the acid required to attain the desired ph.
