Given the following chemical reaction: 2 o2 + ch4 co2 + 2 h2o what mass of ch4 is required to completely react with 100 grams of o2?

Answer : The mass methane required is, 25 g

Explanation : Given,

Mass of oxygen gas = 100 g

Molar mass of oxygen gas = 32 g/mole

Molar mass of methane gas = 16 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 2 moles of react with 1 mole of

So, 3.125 moles of react with moles of

Now we have to calculate the mass of

Therefore, the mass methane required is, 25 g

b.

the accuracy of the data.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
