To find the molecular formula from the empirical formula, you need to know the molar mass of the compound. The empirical formula CH₂O has the following molar masses:
Carbon (C): 12.01 g/mol
Hydrogen (H): 1.01 g/mol
Oxygen (O): 16.00 g/mol
So, the total molar mass of CH₂O is:
(12.01 g/mol) + 2*(1.01 g/mol) + 16.00 g/mol = 30.03 g/mol
Now, you need to compare the molar mass of the empirical formula to the molar mass of the compound to determine the ratio between them.
Let's assume the molar mass of the compound is 60.06 g/mol (just for example).
The ratio between the molar mass of the compo ..read more

According to Le Chatelier's Principle, if C2H4Cl2 is removed from the reaction mixture, the equilibrium will shift to produce more C2H4Cl2 to counteract the loss. Therefore, removing C2H4Cl2 will favor the forward reaction and increase the production of C2H4Cl2.

In my opinion, the best tactics to maximize C2H4Cl2 production are removing C2H4Cl2 as it forms and adding Cl2. Retro Bowl

Biogas is also known as biogas. Under standard conditions, Biogas contains 60% methane by volume and the remaining is carbon dioxide and other gases (knowing that 1 mole of gas under standard conditions occupies a volume of 24.79 liters). A gas tank (liquefied petroleum gas) contains a mixture of propane and butane with a molar ratio of 1: 2. When completely burned, 1 mole of propane gives off 2220 kJ of heat, 1 mole of butane gives off 2850 kJ of heat. and 1 mole of methane gives off 890.5 kJ of heat. On average, a household needs to use up a 12kg gas cylinder every 60 days (assuming all reac ..read more

I was considering calculating the Gibbs, but that would only reveal whether the reaction is not spontaneous.
