A is the answer to this question. Thank you.
We first calculate the heat released:
Specific heat = 3.21 kJ/kgK
Heat released = heat absorbed by calorimeter
Heat absorbed = mcΔT
= 1.9 x 3.21 x 4.542
= 27.7 kJ
Now, we calculate the moles of hexane present:
Moles = mass / Mr
moles = 0.58 / (12 x 6 + 14)
= 0.0067
Heat of combustion = 27.7 / 0.0067 kJ/mol
ΔH(combustion) = 4,134.3 kJ / mol
Answer:
Bases
Explanation:
Most soaps fall under the base category as they are slippery and will taste bitter if you taste it (DONT TRY IT THO).
The uneven distribution of charge between the hydrogen and oxygen atoms primarily leads to its <span>ability to dissolve ionic substances. This is because the unequal sharing leads to the polarity of water. Its polarity makes it dissolve to ionic substances.</span>
