Answer:

CH4 + 2O2 → CO2 + 2H2O

Explanation:

1. Add 2 before H20 to get equal amount of hydrogen on both sides of equation.

2. Add 2 before 02 to get equal amount of oxygen on both sides of equation.

6. The fusion of 4 H-1 nuclei to produce two positrons and one other nuclei.​
KIM [24]

Explanation:

Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.

A pure element unbound or in a diatomic state, such as cl2, always has an oxidation number of ________. a. 1 b. 2 c. magnitude e
nignag [31]

A pure element unbound or in a diatomic state, such as cl2, always has an oxidation number of 0 (zero).

<h3>Why does pure element or a diatomic molecule has zero oxidation state?</h3>

In a neutral substance with atoms of only one element, the oxidation number of an atom is zero. As a result, the oxidation number of the atoms in O2, O3, P4, S8, and aluminum metal is 0. The oxidation numbers for an element in its normal state will be zero. O2 and Cl2 are diatomic gas molecules that occur naturally, thus when they are in that state, they have an oxidation state of zero. Metals like zinc will also have an oxidation number of zero if they are in their natural solid state.

O2 and Cl2 are neutral diatomic, hence they will always have a zero oxidation state. It is impossible for one oxygen atom to have a negative 2 charge while the other has a positive 2. The oxidation states should be 0 if the elements are solids, liquids, or any type of diatomic molecule.
