Answer:
We know that kinetic energy is one of the forms of internal energy, so the release of heat from an object causes a decrease in the average kinetic energy of its particles.
40 g Ar.......6.023*10^23 atoms
x g Ar.......3.8*10^24 atoms
x=40*3.8*10^24/(6.023*10^23)=252,365g Ar
Answer:
option A = S(s) + O₂(g) → SO₂ (s)
Explanation:
Chemical equation:
S(s) + O₂(g) → SO₂ (s)
when sulfur burned in the presence of oxygen it produce sulfur dioxide. The sulfur dioxide can further react with oxygen to produce sulfur trioxide and then react with water to form sulfuric acid.
Uses of sulfur dioxde:
It is used as a solvent and reagent in laboratory.
Sulfur dioxide is used to produce sulfuric acid.
It is used as a disinfectant
It is also used as a reducing agent.
It is used to preserve the dry food.
Answer:
a. Kenya's growth seems to be a large population influx, an increase in the pre-reproductive stage.
b. There is a decrease in the younger generation, meaning that the reproductive part of the population is more than the pre-reproductive part. Which means less of an incline in population.
c. You can see the differences within the countries, that the growth rate in Kenya is extremely high, the United States more moderate, while Germany is somewhat even throughout. Germany is not growing much in comparison to Kenya.
