you first have to set it up as a proportion which would be:
<u>x</u> = <u>15</u>
1000 100
The answer would be 100x=15000 after cross multiplying
After you divide 15000 by 100 you get x=150
That means that 150 people didn't answer the phone.
The collision theory in chemistry is used for the prediction of the rates of the chemical reactions, it is mainly used for the calculation of the rate of the chemical reactions occurring in the gaseous state.
The main assumption of this theory is reacting substance (atom or molecule) must come and collide to react and form a product. It was proposed by Max Trautz in the year 1916.
Is there anything else that needs to be added to this in order for me to answer this question??
Answer:
Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:
- They increase the nitrate levels in the soil which is a rich supplement for nitrogen needed by plants for their growth.
- They are easily available and user-friendly but should be used in regulated amounts as an excess of nutrients like nitrogen and phosphorus present in synthetic fertilizers enter the aquatic ecosystem.
<u>Explanation:
</u>
Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants. Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.
When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water. That is why such fertilizers should be used in regulated amounts.
