How much fertilizer is applied each year on lawns throughout the united states?
Stells [14]

Answer:

1.8 pounds  of Nitrogen per year; (based on 1000 square feet per application) for cool season grasses.

Explanation:

The above application shows  an average of 0.9 pounds of inorganic and organic  nitrogen per 1000 square feet per application . Therefore not more than 0.9 pounds of nitrogen will be needed  per application.And for a whole year 1.8 pounds of Nitrogen per year will be needed.

This calculation was based on 1000 per square.But most lawn are not 1000 per square, therefore calculation can be done using the 1000 per squares as the  reference point .

AMMONIA and its solutions, AMMONIUM NITRATE AND UREA  (which is organic source)<u>are the sources of this Nitrogen</u>.

Urea is non -explosive in nature and solid. However, ammonia and ammonium Nitrate are both explosive.

Which of the following is not an indication of a chemical reaction?
podryga [215]
<span>The correct answer is a substance freezes. That is because this is a change of a physical property, not a chemical one. This shows that the chemical is still exactly the same and will react the same, it is only different in its state of matter, which is irellevant for its chemical properties. It will still react the way it's supposed to react when combined with other chemicals.</span>
