The reaction produces 6 g of carbon dioxide.
The word equation is
methane + oxygen → carbon dioxide + water
12.2 g + 4 g → x g + 20 g
The <em>Law of Conservation of Mass</em> tells us the total mass of the reactants must equal the mass of the products. Then
12.2 g + 14 g =<em> x</em> g + 20 g
<em>x</em> = 12.2 + 14 – 20 = 6
The mass of carbon dioxide is 6 g.
<em>Note</em>: The answer can have <em>no decimal places</em> because you gave none for the masses of oxygen and water.

Chlorine and Bromine are in the same group
Answer:
Thomson placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery, minus the mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:
The cathode ray is composed of negatively-charged particles.
The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.
These subatomic particles can be found within atoms of all elements.
While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.
