Answer:
C
Explanation:
the n value must always be greater than the l value
Some parts of the planet undergo very little seasonal change due to their proximity to the equator and the poles. This means that their position relative to the sun and the earth's rotation varies hardly at all.
Answer:
3 is the coefficient of oxygen.
Explanation:
Chemical equation:
CH₃OH + O₂ → CO₂ + H₂O
Balanced chemical equation:
2CH₃OH + 3O₂ → 2CO₂ + 4H₂O
The given reaction is combustion reaction. In this reaction methanol is burn in the presence of oxygen and produces carbon dioxide and water.
The balance equation show reaction also follow the law of conservation of mass.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Explanation:
Force = Mass × Acceleration
20 = 2.0 × A
A = 20/2 = 10m/s^2
1. the periodic table is arranged in order of atomic number
