Answer:
photochemical
hydrocarbon
Explanation:
Morning commuter traffic in cities contributes to<u> photochemical</u> smog. In this type of air pollution, a mixing of <u>hydrocarbons</u> from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
<em>Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog</em>
Answer:
Coal and oil (if there are two answers)
Answer:
the salt is dissolved, resulting in a homogeneous solution.Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Answer: el agua es importante para nosotros porque nos da muchos beneficios como por ejemplo nos bañamos con agua, tomamos agua para seguir hidratados, lavamos ropa con agua aunque sea en una máquina esa máquina requiere agua para poder lavar la ropa . Lavamos los platos sucios con agua , cocinamos con agua como uno de nuestros ingredientes . Así que todo sería differente de una manera mala si no
