H₂S gas burns in the presence of O₂ to form SO₂ and H₂O
complete reaction is as follows
2H₂S + 3O₂ ---> 2SO₂ + 2H₂O
stoichiometry of H₂S to SO₂ is 2:2
Avagadros law states that volume of gas is proportional to number of moles of gas. Therefore volume ratio between reactants and products is equal to the molar ratio.
hence, volume ratio of H₂S to SO₂ is 2:2
2 L of H₂S forms 2 L of SO₂
therefore 121 L of H₂S forms 121 L of SO₂
volume of SO₂ produced is 121 L
Answer:
- Shredded leaves
- Small bits of straw or hay, finely shredded
- Shredded paper
- Torn cardboard in small bits
Tip: The smaller the pieces, the faster it decomposes. Even fruits and veggies can decompose quickly if they are blended or chopped into small portions. If you add some worms to the compost pile, everything should decompose quickly! Just remember to avoid eggshells because they take FOREVER to decompose.
Answer:
the best estimate is 34.69 g
Explanation:
the best estimate is 34.69 gm because when it is rounded it becomes 34.70 gm which is near to actual weight 34.75 gms
The damaging of human activities
Answer:
The statements which are correct are;
c) (i), (ii) and (iv)
Explanation:
The chemical equation is presented as follows;
2Fe(s) + 3H₂O(g) → 3Fe₂O₃(s) + 3H₂(g)
Therefore, we have;
i) The iron gains oxygen atoms and therefore gets oxidized
The iron loses 3 electrons each to become oxidized to Fe³⁺ in Fe₂O₃
ii) The water loses oxygen and therefore it is getting reduced
iv) The water donates oxygen and therefore it is acting as the oxidizing agent
The correct options are (i), (ii) and (iv).
