The electron configuration of Nitrogen is
1s ^2 2s ^2 2p^ 3
There are 3 electrons in the 2p sub level of nitrogen.
Answer:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Explanation:
The thermochemical equation for the combustion of methane can be obtained as follow:
Methane (CH₄) under goes combustion in the presence of air (O₂) to produce carbon dioxide (CO₂) and water (H₂O). This can be represented in the equation below:
CH₄ + O₂ —> CO₂ + H₂O
Thus, we can balance the equation as follow:
CH₄ + O₂ —> CO₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H₂O as shown below:
CH₄ + O₂ —> CO₂ + 2H₂O
There are a total of 4 atoms of O on the right side and 1 atom on the left side. It can be balance by putting 2 in front of O₂ as shown below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Now the equation is balanced.
Answer: Light Is Also a Particle!
Now that the dual nature of light as "both a particle and a wave" has been proved, its essential theory was further evolved from electromagnetics into quantum mechanics. Einstein believed light is a particle (photon) and the flow of photons is a wave.
Explanation:
The two strands of a DNA molecule must be separated
SO₄²⁻ +NH₃ → SO₃²⁻ + H₂O +N₂
The balanced of the above redox reaction is as below
3SO₄²⁻ + 2NH₃ → 3SO₃²⁻ + 3 H₂O + N₂
Explanation
According to the law of mass conservation the number of atoms in the reactant side must be equal to number of atoms in product side.
Inserting coefficient 3 in front of SO₄² , 2 in front of NH₃, 3 in front of SO₃²⁻ and 3 in front of H₂O balance the equation above. This is because the number of atoms are equal in both side.
for example there are 2 atoms of N in both side of the reaction.
