The statement presented above that is not true about paper recycling is; A) Recycling one ton of newspaper can save 100 trees.
Paper recycling are the processes of reprocessing waste paper such as old newspapers and magazines into new paper products for reuse. Apart from saving trees from being cut, paper recycling has many other significant benefits such as reducing water and air pollution, saving on the use of water resources and energy.
For every ton (200 pounds) of newspaper that is recycled, 17 trees are saved.

Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
