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
Explanation:
Cs has a higher rate of reaction because it's easier to remove an electron from it, thereby leading to faster reactivity
<h2>Answer:</h2>
<u>Biomagnifiaction is the accumulation of the toxic chemicals in organisms up to the dangerous level and successively contributed to the food chain.</u>
<h3>Explanation:</h3>
Bio magnification which is also known as bio accumulation or bio amplification.
In bio magnification a compound which is chemical in nature is accumulated due to the eating of food that contains elements.
As in case pf plants, fertilizers and chemicals are sprayed on the plants which are then consumed by the other organisms and become the part off that organism in the elevated form. That organism is then consumed by the other organisms.
And then in this process, the chemical will be transferred to the highest trophic level of food web.
