Answer:
It is always twice the value of the actual yield.
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.
Answer:
151 g/mol
Explanation:
When a nonvolatile substance is added to a solvent, the freezing point of the solvent is changed, which is called cryoscopy. When temperature change can be calculated by:
ΔT = Kf*W
Where Kf is the molal freezing point constant of the solvent and W is the molality of the solution.
For cyclohexane, Kf = 20.2 °C/molal, and the freezing point is 6.4 °C, so:
6.4 - 1.05 = 20.2 * W
20.2W = 5.35
W = 0.26485 molal
The molality is:
W = m1/m2*M1
Where m1 is the mass of the solute (in g), m2 is the mass of the solvent (in kg), and M1 is the molar mass of the solute. So:
0.26485 = 2.00/0.05M1
0.0132425M1 = 2.00
M1 = 151 g/mol
Answer:
because that is the last group the ones before it are more reactive im sorry if this not what you were looking for.
HCO3^1- because sodium has a 1+ charge
