Unfortunately, we have not fully solved the 'nitrogen problem'. To do this, we must halve the amount of nitrogen we dump into the environment by mid-century or our ecosystems will face epidemics of toxic tides, lifeless rivers, and dead oceans. And that to do that will require, among other things, almost doubling the efficiency of nitrogen use on the world’s farms.
Answer:
45 meters
Explanation:
If it takes the slug 20 minutes to travel 15 meters, you multiply the 15 by three to get the distance for 60 minutes.
Assuming the conditions of the reaction are maintained and appropriate for the reaction to still occur, the reaction rate can be affected by increasing the concentration of the reagents used in a reaction. It will speed it up.
Answer: a bench made of composite plastic
Explanation:
The chemical weathering can be defined as the process in which a chemical causes the degradation and decomposition of the rocks into small particles. The iron rods, feldspar, and marble will weather considerably with a greater danger as the have a strong solid body. But plastic when exposed to a chemical agent usually melts and thus there is least or no danger of chemical weathering of plastic.
