Explanation:
Amines are organic compounds derived from ammonia by replacing the hydrogen atoms, one at a time with carbon-containing groups. The functional groups are R-NH₂, R₂-NH, and R₃-N
Amines are classified into primary, secondary, or tertiary according to the number of substituted hydrogen.
From the given question.
A compound with the molecular formula C₅H₁₃N was given;
The possible eight structural formula of the compound and those that exhibit chirality can be seen in the attached image below.
Answer is: 5,1 mol KOH.
V (KOH) = 0,8l = 0,8 dm³.
c (KOH) = 6,4 mol/dm³.
V - volume of solution.
c - concentration of solution.
c = n÷V
n - amount of substance.
n (KOH) = c·V = 6,4 mol/dm³ · 0,8 dm³ = 5,12 mol.
Potassium hydroxide (KOH) can<span> </span>dissolve<span> in water at room temperature.</span>
Answer:
Mohammed has less kinetic energy
Explanation:
m=Kg
V= m/s
KE= kinetic energy = J
the way you work out the answer is:
KE = 1/2 × m × v squared
Answer:
the reaction is exothermic
Explanation:
heat will be produced from the reaction
Answer: C.
Explanation: Alcohol floats on oil and water sinks in oil. Water, alcohol, and oil layer well because of their densities, but also because the oil layer does not dissolve in either liquid. The oil keeps the water and alcohol separated so that they do not dissolve in one another. ... Water sinks because it is more dense than oil.
