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
They are made up of chains of Hydrogen and c) Carbon
Answer:
Carbon Monoxide / Carbon Dioxide / Sulfur and Nitrogen Dioxide
Explanation:
The appropriate answer is b. the lake effect. Buffalo is located on the north eastern shore of the Lake Erie. The high snowfall in this area is due to the fact that cold air masses will move across the expanse of the warmer lake water during the winter months. This warms the layer closest to the water causing it to pick up moisture from the lake. Once the moisture rises through the air mass it will freeze and form snow.
