A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
Mariana [72]
<h3><u>Answer: </u></h3>

A. NO, the equation is NOT balanced.

B. C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂

<h3><u>Explanation:</u></h3>
  • The chemical equation of cellular respiration is given by:  

C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂

Where glucose or sugar is broken down in presence of oxygen in presence of oxygen to yield energy in the form of ATP and water and carbon dioxide as a byproduct.

  • The given chemical equation is not balanced as the number of atoms of each element on reactant side are not equal to those on the product side.  
  • Initially,there are 12 Hydrogen atoms, 18 Oxygen atoms and 6 Carbon atoms on each side.  To balance the equation we put a 6 on carbon dioxide and a 6 on water on the product side.
  • The balanced equation will be;

C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂

The biodiversity of cultivated crops is currently under threat from industrial
DENIUS [597]

Answer:

The wastes or run off of the industrial farming enters the water and nearby cultivated crops, this waste consist of chemicals and pesticides mostly, that are the cause of destruction of not only the cultivated crops but also the useful soil-borne rhizoshpere bacteria too. On the other hand climate change impacting from emission of greenhouse gases, increase air pollution and also cause deforestation. Such circumstances could all lead to the extinction of important crops.

In order to avoid these problems, proper waste management systems should be developed to dispose the waste of industries and others at area that is far from the population or cultivation. The climate change resulting from the pollution could be avoided by the use of filtered products for the smokes, so that filter could absorb harmful substances and the smoke released in air would not be that much toxic. Moreover, there is the need to identify and grow such crops that can adapt these environmental changes.
