B) Write a few paragraphs describing the chemical reaction and explaining the energy change in the reaction. Your document should:
i.
ii.
identify the reactants and products.
describe the change in energy that occurs as bonds are broken and formed.
identify how the potential energy of the reactants compares to the potential energy of
the products.
state and explain the net change in enthalpy.
iii.
iv.
V
identify whether the reaction is endothermic or exothermic.
explain how energy is conserved between the reaction and the surrounding
environment
vi.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
