The first one is an alkane, the second is an alkene, and the third is an alkyne. The suffix of the compound tells you what kind of hydrocarbon it is.
Answer:
the temperature and pressure can greatly affect the volume of a substance. especially with gases. as with mass increasing and decreasing the amount of material also increases and decreases the volume of the substance.
Answer:
155 kJ
Explanation:
The energy change will be the energy of the reactants less the energy of the products. And the energy of each compound is the sum of the energy of their bonds. Let's call y the N-Br strength.
3HOBR = 3x(459 + 201) = 1980 kJ
NH₃ = 3x386 = 1158 kJ
3H₂O = 3x(2x459) = 2754 kJ
NBr₃ = 3y
3y + 2754 - 1158 - 1980 = 81
3y -384 = 81
3y = 465
y = 155 kJ
