Recall that areas with high net primary productivity not only produce high levels of biomass rapidly, they also take up large am

ounts of CO2 and give off large amounts of oxygen. What is the likely result of the increasing amounts of fertilizers in the major rivers emptying into oceans?

Answer:

The eutrophication of oceans.

Explanation:

This is the result of an increase in phosphates and nitrogen dissolved in water, at the end when it reaches the oceans, they are going to deposit in the bottom of the ocean and they are going to promote the production of algae.

With an increase of the population of algae, the sunlight will not reach the bottom, will consume the oxygen of the oceans, leaving a reduction in fish and other living things population.

What is one way to create a negative ion?
san4es73 [151]

Answer:

Burn beeswax candles. They clean the air, produce negative ions, and assist with allergy and asthma reduction. Run an indoor water fountain. The force or energy of falling water causes the neutral particles in air to split which frees electrons to attach to other air molecules resulting in negative ions.

Marysya12 [62]

Answer:

C) 0.457

Explanation:

The ratio between O2 and H2O is 1:2 according to the balanced equation. You can find how many moles is O2 by : 5.12/22.4 = 0.22857 ( 1 mole = 22.4 litters)

Moles of H2O will be 0.22857 * 2 = 0.457142.

Therefore answer C)

How many grams of ammonia are produced when 1.0 mole of nitrogen reacts
Varvara68 [4.7K]

Answer: N2(g) + 3H2-> 2NH3(g)  This is the balanced equation

Note the mole ratio between N2, H2 and NH3.  It is 1 : 3 : 2  This will be important.

 

moles N2 present = 28.0 g N2 x 1 mole N2/28 g = 1 mole N2 present

moles H2 present = 25.0 g H2 x 1 mole H2/2 g = 12.5 moles H2 present

Based on mole ratio, N2 is limiting in this situation because there is more than enough H2 but not enough N2.

 

moles NH3 that can be produced = 1 mole N2 x 2 moles NH3/mole N2 = 2 moles NH3 can be produced  

grams of NH3 that can be produced = 2 moles NH3 x 17 g/mole = 34 grams of NH3 can be produced

 

NOTE:  The key to this problem is recognizing that N2 is limiting, and therefore limits how much NH3 can be produced.

Explanation: here you go!! good luck! hope this helped
