Answer:
the correct answer is 36
Explanation:
The two substances are sodium chloride and lead nitrate
In case of sodium chloride;
mass of water = 100 kg
solubility of sodium chloride = 54 g / 100 g of water
Therefore the mass of sodium chloride required for full saturation,
L = (54/100) x 100 kg = 54 kg
In case of lead nitrate;
mass of water = 200 kg
mass of lead nitrate = 36 kg
if the solution is fully saturated, solubility of lead nitrate (g per 100 g of water)
k = (36/200) x 100 g = 18 g
k can be also written as 18 kg per 100 kg of water.
thus the difference in k and l = (54-18) = 36.
Answer:
Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.
