Answer:
El motor que las permite vencer la gravedad es la evaporación del agua que tiene lugar en las hojas.
Explanation:
Example 1: FOREST FIRES
September 24, 2015 - Forest Fire in Indonesia continue to cause smog and haze (Atmosphere) across the region, with air pollutants reaching hazardous levels overnight in Singapore.
The poor air quality shift in wind direction transporting smoke and haze from land and forest (Biosphere) fires in South Sumatra, Indonesia. Their District continues to lead in the number of active fire alerts, with 423 hotspots (Lithosphere) in the last week.
The particulate matter in the air falls out, smothering plants, enriching the soil and thereby moving towards seas, rivers (Hydrosphere) and other water forms that can endangered human's health.
Example 2: DROUGHT
April 8, 2016- Swathes of corn stand withered on the parched rolling hills near the farming town in the Southern Philippines, while shallow cracks scar were once fertile rice paddies. (Biosphere)
El Nino is wreaking havoc in agriculture-rich Cotabato province.
That the villagers are in difficult situation of nothing else to eat. After a lot of incident happened, one of the villagers complained back pain and headache after the rough sleeping of several days.
Unfortunately, he died due to heat stroke of the recent changes in temperature due to Global Warming. (Atmosphere) The animals have nothing to feed the fields are dry making the soil (Geosphere / Lithosphere) less fertile for plants.
The farmers experienced scarce of water (Hydrosphere), crop failures and starving, land drying livestock as well as shortage of potable water.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Oxidizing agent is the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction in which, it gains electrons and also the oxidation state of the substance gets reduced.
Reducing agent is the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction in which, it looses electrons and the oxidation state of the substance is increased.
For the given chemical equation:
Half reactions for the given chemical reaction:
Copper is loosing 2 electrons, thus it is undergoing oxidation reaction and is considered as a reducing agent.
Silver ion is gaining 1 electron per atom, thus it is undergoing reduction reaction and is considered as an oxidizing agent.
Hence, is considered as an oxidizing agent and therefore the correct answer is Option B.
