Answer:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g)
Explanation:
In the industry, hydrogen is prepared from water and hydrocarbons. Water gas being the major method of preparation of hydrogen industrially.
The water-gas reaction is an industrial process in which steam is passed over red-hot coke giving a gaseous mixture of carbon monoxide and hydrogen:
C + H2O(g) → CO + H2.
The mixture of CO and H2 is Futher passed through steam according to the equation:
CO(g) + H2(g) + H2O(g) ==> CO2(g) + 2H2(g) to give hydrogen and carbon dioxide.
Average kinetic energy of a particle :
0.5 mv^2 = kT/2
so the kinetic energy = kT/2
assuming the same value of K
T1 = -49 + 273 = 224
T2 = 287 + 273 = 560
E2 / E1 = kT2 / 2 / kT1 / 2
E2 / E1 = T2 / T1
E2 / E1 = 560 / 224 = 2.5
so the average kinetic energy of the particle increases by 2.5
Ans is B.Bromine. Only two elements are liquid at room temperature ( mercury and Bromine) . Helium and chlorine, arsenic are gases.
Answer:
The retention factor of an ion is 0.10 .
Explanation:
Retention factor is defined as ratio of distance of distance traveled by solute to the distance traveled by solvent on chromatogram.
We have:
The retention factor of an ion :
Answer:
The correct answer to the following question will be Option B (temperature of the water).
Explanation:
- The solubility of that same salt which appears whenever the substance is added in some kind of a fluid which already incorporates another origin of many of its atoms.
- The solubility of such a substance throughout a given quantity of water is predominantly dependent on the whole of the water temperature.
