the reaction between methane and water vapour produces carbon dioxide gas and hydrogen gas in the following reaction: CH4(g)+2H2O(g)=CO2(g)+4H2(g)
you initially add 2.00 mol of methane and 6.00 of water vapour to an 8.00L container. calculate Keq for the forward reaction if the equilibrium concentration of water vapour was measured to be 0.56mol/L
An air-dry soil with a moisture content of 35% by weight is to be used in a pot
experiment. If each pot is to have 20 kg oven-dried soil, how much of the air-dry soil should
be weighed into the pot and how much is the moisture of that soil in kg?
