How many grams of h2 would be formed if 34 grams of carbon reacted with an unlimited amount of h2o? the reaction is:

c + h2o → co + h2

the atomic mass of c is 12.01 g/mole. the atomic mass of h2 is 2.016 g/mole. finish the problem by choosing the correct format for dimensional analysis.

Answer : The mass of will be, 5.66 grams

Explanation : Given,

Mass of C = 34 g

Molar mass of C = 12 g/mole

Molar mass of = 2 g/mole

First we have to calculate the moles of carbon.

Now we have to calculate the moles of .

The given balanced chemical reaction is,

From the balanced reaction, we conclude that

As, 1 mole of C react to give 1 mole of

So, 2.83 mole of C react to give 2.83 mole of

Now we have to calculate the mass of .

Therefore, the mass of will be, 5.66 grams

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
