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
Therapies aimed mainly at understanding one's thoughts, feelings, and behaviors are referred to as Cognitive behavioral therapy (CBT)
<h3>What is Therapy?</h3>
This refers to the treatment that is given to a person for a mental problem that stems from stress, abuse, etc.
Hence, we can see that based on the type of therapy that is used to understand the thoughts and feelings of a person in order to give them treatment is known as Cognitive behavioral therapy (CBT)
