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

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
