Equal weights of methane and hydrogen are mixed in an empty container at 25 degrees Celsius The fraction of the total pressure exerted by hydrogen is?
1/2
What bonds are broken during the combustion of mathane to form water and carbon dioxide?
methane is a gas
What happens when Mathane burns in air?
MEthane or CH4 with complete combustion will turn into CO2 and H2O The formula for complete combustion of methane: CH4 + 2O2-> CO2 + 2H2O
What are the Densities of Methane from 20-120 degrees C?
The density of methane gas at +25 degrees Celsius is 0.656 kg/m3. The density of methane liquid -90 degrees Celsius is 162 kg/m3. The SI density standard is kg/m3.
What is the state of ethanol at 25 degrees?
A gas under normal pressure. Methane has a boiling point of -1600C. It does depend on the pressure at extemely high pressures methane will be a liquid.

What pressure will condensate drop out of methane gas form and become liquid condensate hydrocarbons?
If you are asking how much pressure you would have to compress methane to in order to liquify it at room temperature, the answer is that methane won't liquify at room temperature. The critical temperature for methane is -87.2 degrees centigrade. Above that temperature it will not liquify no matter how much pressure you apply. At -82.7 degrees centigrade it would take a pressure of 45.96 bar to get it to liquify. See: http://www.chem.purdue.edu/gchelp/liquids/critical.html

What state is methane at -50 degrees?
The state of matter in which Methane would be at 25 degrees would be a Gas. Professor Houden
Is methane a gas solid or liquid?
beacuse it is becaiuse its called methane and starts with a M and ends with E :)
A sample natural gas contains 8.24 moles of methane 0.421 moles of Ethelin o116moles of propane if the total pressure of the gases is 1.77atm what are the partial pressures of the gases?
mole fraction of methane = (8.24)/(8.24+0.421+0.116) = 0.939 mole fraction of ethelin = (0.421)/(8.24+0.421+0.116) = 0.048 mole fraction of propane = (0.116)/(8.24+0.421+0.116) = 0.0132 Partial pressure = Total pressure * mole fraction P(i) = P(t) * X(i) P(methane) = 1.77 atm * 0.939 = 1.66 atm P(ethelin) = 1.77 atm * 0.048 = 0.085 atm P(propane) = 1.77 atm * 0.0132 = 0.0234 atm 1.66 + 0.085 + 0.0234 = 1.7684 --> 1.77 atm
What is methane at 1000 degrees Celsius?
