Answer: Positive effects: mass production of fertilizers, alkaline cleansers, refrigerant gas, dyes, explosives
Negative effects: heath problems, negative effects on soil organisms and soil organic matter, imbalances to the nitrogen cycle, high fossil fuel energy inputs, production of deadly weapons
Explanation:
The Haber process (also called Haber Bosch process) is used to produce ammonia from nitrogen and hydrogen under the high pressure. Basically, it's an artificial nitrogen fixation process. This method has both positive and negative effects on modern society.
Positive sides: ammonia is mainly used for mass production of fertilizer, which allows more food for everyone. It can be used for production of alkaline cleansers, refrigerant gas, dyes and explosives. Ammonia is also used in production of synthetic polymers, due to its role in the manufacturing of cyanide.
Negative sides: ammonia is a toxic gas, it can irritate eyes and lungs. Because of that, the excess nitrogen in soil and water coming from synthetic fertilizers can cause health problems. It is harmful for humans and animals, but it can also be harmful for plants. Environmental factors are also important. Because of the mass fixation, there is imbalance in the earth’s nitrogen cycle. Also, fossil fuels are used as a source of power for machinery in Haber's process, which increases emissions into the atmosphere. And, at least ammonia is a major component of weapons including great number of bombs.
These problems are a bit interesting. :)
First let's write the molecular formula for ammonium carbonate.
NH4CO3 (Note! The 4 and 3 are subscripts, and not coefficients)
17.6 gNH4CO3
Now to convert to mol of one of our substances we take the percent composition of that particular part of the molecule and multiply it by our starting mass. This is what it looks like using dimensional analyse.
17.6 gNH4CO3 * (Molar Mass of NH4 / Molar Mass of NH4CO3)
Grab a periodic table (or look one up) and find the molar masses for these molecules! Well. In this case I'll do it for you. (Note: I round the molar masses off to two decimal places)
NH4 = 14.01 + 4*1.01 = 18.05 g/mol
NH4CO3 = 14.01 + 4*1.01 + 12.01 + 3*16.00 = 78.06 g/mol
17.6 gNH4CO3 * (18.05 molNH4 / 78.06 molNH4CO3)
= 4.07 gNH4
Now just take the molar mass we found to convert that amount into moles!
4.07 gNH4 * (1 molNH4 / 18.05 gNH4) = 0.225 molNH4
Answer: THE ANSWER IS OZONE WEEEE a layer in the earth's stratosphere at an altitude of about 6.2 miles (10 km) containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.
Explanation:
Answer:
The two ways to measure mass are subtraction and taring.
Answer:
Break up the soil to increase the number of pores should be your answer.
Explanation:
If you do that it will increase the amount of water in the plant.
