Highest boiling point between NH3 HCl H2 and KI?
The highest boiling point beween these compounds: potassium iodide (KI) with 1 330 0C.
What volume of H2 can be obtained from 100 cm3 of methane at standard temperature and pressure?
Assuming you are referring to the reaction of CH4 + H2O → CO + 3 H2, and not combustion of methane (CH4 + 2O2 ==> CO2 + 2H2O where NO H2 is formed), then ...100 cm3 CH4 = 0.1 litersmole ratio CH4 : H2 = 1 : 3 (see balance equation above).Liters H2 produced from 0.1 liters CH4 = 3 x 0.1 = 0.3 liters of H2 can be produced.
What is the melting point and boiling point of hydrogen?
The freezing point (same as melting point) of H2 is 14.01 K (−259.14 °C, −434.45 °F)The boiling point of H2 is 20.28 K (−252.87 °C, −423.17 °F)
How do you balance C H2-----CH4?
The balanced equation for the reaction of C + 2H2 → CH4 is: C + 2H2 → CH4. This equation is already balanced. Each side has 1 carbon atom and 4 hydrogen atoms.
How do you balance CH4 H2O --- H2 CO?
To balance the equation CH4 + H2O → H2 + CO, you need to change the coefficients. Start by balancing the carbon atoms - there is 1 carbon on each side so you can leave that as is. Next, balance the hydrogen atoms by adding a coefficient of 2 in front of H2 on the product side. Lastly, balance the oxygen atoms by adding a coefficient of 1 in front of H2O on the reactant side to give you CH4 + H2O → 2H2 + CO.
C+H2–>CH4?
It is propane
Highest boiling point between NH3 HCl H2 and KI?
The highest boiling point beween these compounds: potassium iodide (KI) with 1 330 0C.
Why does H2 have the lowest normal boiling point?
From all of the diatomic gasses, Hydrogen (H2) is the gas with the lowest molecular mass and NO dipole moment or polar bond at all. 20.28 K, -252.87 °C, -423.17 °F Boiling point of Helium (monoatomic) is even lower (4.22 K, −268.93 °C, −452.07 °F); this is because there are no valence electrons moving BETWEEN two nuclei causing some oscilating charge displacement and attraction, as in H2.

Which gas is among CO2 CH4 H2 will diffuse faster and why?
H2 will diffuse fastest as it has the least molecular weight.

How many liters of hydrogen gas are needed to react with CS2 to produce 2.50 L CH4 at STP?
Based on the balanced chemical equation for the reaction between hydrogen gas (H2) and carbon disulfide (CS2) to produce methane (CH4), you need a 1:1 mole ratio of H2 to CH4. At STP conditions, 1 mole of any gas occupies 22.4 L. Therefore, if 2.50 L of CH4 is produced, you would need 2.50 L of H2 to react completely with CS2.
What is the balanced Equation showing the reaction of carbon and hydrogen to form methane?
The molecular formula for Methane is CH4 It's 1 atom carbon, 2 hydrogen molecules (Hydrogen molecules come in H2 gases) so the formula would be C + 2(H2) = CH4
Which gas from among CO2 CH4 H2 will diffuse the fastest and why give the reason?
Hydrogen (H2) will diffuse the fastest because it has the smallest molecular weight, which corresponds to higher average speeds of the gas particles at a given temperature. This allows hydrogen molecules to move more quickly through a medium compared to the heavier carbon dioxide (CO2) and methane (CH4) molecules.
What is the melting point and the boiling point of hydrogen in degrees Celsius?
The boiling point of hydrogen is -252.88°C. or -423.18 °F
