Hydrogen gas can be produced by reacting a mixture of methane and steam in the presence of a nickel catalyst.
The reaction conditions are a temperature of 700° C and a pressure of 5 atmospheres.
The equation for the reaction is
CH4(g) + H2O(g) = CO(g) + 3H2(g)
(delta)H = +206 kJ/mol
(a) Calculate the volume, in dm^3, of hydrogen gas at rtp that is produced when
10 tonnes of methane gas completely react with steam.
(molar volume of hydrogen at rtp is 24 dm^3)
Give your answer in standard form.

explanation:

i think option no d is the correct answer

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
