Explanation:
Shifting, labor intensive and monoculture are different in terms of description,restrictions and problem.
Shifting is an agriculture method in which an area if land is cultivated for a while and abandoned for the soil to regain and preserve it's fertility. It is done to restore soul fertility.
It has restrictions because it is done in places where there is large areas of land, if there is not large area of land, it will be done.
It can lead to defforestation because trees are cut fine for land cultivation and after a while the land is abandoned and trees are cut down some where else too.
Labor intensive refers to agricultural industry requiring or needing large amount of labor to produce agricultural products. Labor intensive is restricted to areas where there is low or no people who can engage in agricultural services.
Labor intensive require high skilled people which might not be available.
Monoculture is a farming system where by a single crop is cultivated in an area of land.
The problem of monoculture is that it displaces species and nutrients occuring naturally in an ecosystem.
Monoculture is restricted in areas where diversity of crops are needed.
Answer: 24.1%, under below assumptions.
Justification:
The question is quite ambiguous, because one of the data is not clearly stated. It says that the mixture consists on two compounds:
- sodium bicarbonate, and
- ammonium bicarbonate
.After, it says that it is 75.9 % bicarbonate, but it does not specify which bicarbonate, it might be the sodium bicarbonate or the ammonium bicarbonate. It is apparent that you omitted that information by error.
Given that later, the question is <span>what the mass percent of sodium bicarbonate is in the mixture, it is supposed that the 75.9% content is of ammonium bicarbonate.
With that said, you can calculate the mass percent of sodium bicarbonate, because there are only two compounds and so you know that both add up the 100% of the mixture.
In formulas:
100% = %m/m sodium bicarbonate + %m/m ammonium bicarbonate = 100%
=> % m/m sodium bicarbonate = 100% - % m/s ammonium bicarbonate
=> % sodium bicarbonate = 100% - 75.9% = 24.1%
Answer: 24.1%

Explanation:
Algae are plant-like protists capable of photosynthesis in their cells (chloroplast). Like every other living organism that grows and reproduce, algae also requires nutrients for these processes to effectively occur.
Algae makes use of inorganic nutrients including sulphates, phosphates, nitrates etc which are found in fertilizers, detergents etc. In the presence of these compounds, algae tends to grow excessively to form a BLOOM. Hence, according to the question, nitrates and phosphates are the two inorganic nutrients algae makes use of.
C) can give up electrons more readily than others.
