Integrated Problem 01.69 With current spectroscopic techniques, chemists are generally able to determine the structure of an unk

nown organic compound in just one day. These techniques have only been available for the last several decades. In the first half of the twentieth century, structure determination was a very slow and painful process in which the compound under investigation would be subjected to a variety of chemical reactions. The results of those reactions would provide chemists with clues about the structure of the compound. With enough clues, it was sometimes (but not always) possible to determine the structure. As an example, try to determine the structure of an unknown compound, using the following clues:
•The molecular formula is C4H10N2.
•There are no bonds in the structure.
•The compound has no net dipole moment.
•The compound exhibits very strong hydrogen bonding.
You should find that there are at least two constitutional isomers that are consistent with the information above.

Determine the heat energy needed to raise the temperature of 120 grams of ice at -5 to steam at 115°
CaHeK987 [17]

Answer:

Q = 30355.2 J

Explanation:

Given data:

Mass of ice = 120 g

Initial temperature = -5°C

Final temperature = 115°C

Energy required = ?

Solution:

Specific heat capacity of ice is = 2.108 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Q = m.c. ΔT

ΔT = T2 -T1

ΔT = 115 - (-5°C)

ΔT = 120 °C

Q = 120 g × 2.108 j/g.°C × 120 °C

Q = 30355.2 J

Improperly maintained landfills result in the release of ________ into the atmosphere
Ket [755]
When landfills have a very poor maintenance, it would likely result in the release of harmful gases into the atmosphere. Among these poisonous gases released are carbon dioxide and methane in which if inhaled in an excessive amount, it could cause respiratory illnesses or it could be fatal.
