Wood is made mostly of cellulose and has a chemical formula of C. H.00. Which of the following equations represents the cellulose combustion reaction?

Option B.

C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O

Explanation:

To know which option is correct, we shall write the balanced equation for the combustion of cellulose. This is illustrated below:

C₆H₁₀O₅ + O₂ —> CO₂ + H₂O

There are 6 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 6 before CO₂ as shown below:

C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O

There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:

C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O

There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by writing 6 before O₂ as shown below:

C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O

Now, the equation is balanced.

Thus, option B gives the correct answer to the question.

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
