Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
Answer:
The Gods cannot help save someone from poor decisions he/she has made.
Explanation:
Creon has committed a grave sin by the killing of his own kin partly because he wanted the throne and thus has brought ruin to his own people after the unknowing act of Oedipus and now his willingly killing of his own kin.
When he is repenting and praying to the god for forgiveness, it is through the character of Charagos that the authorial voice speaks and tells him something.
That is being told to him that he must pay for what he has done and he will not be forgiven
Answer:
a ship floats because of the mass and the parts of the ship help with staying on top of the water the buoyancy force is helpful for the ship to float which means weightless-airlessness and lightness.
