Which of the following statements describes the results of this reaction? c6h12o6 + 6 o2 → 6 co2 + 6 h2o + energy a) c6h12o6 is oxidized and o2 is reduced. b) o2 is oxidized and h2o is reduced. c) co2 is reduced and o2 is oxidized. d) c6h12o6is reduced and co2 is oxidized. e) o2 is reduced and co2 is oxidized.

The correct answer is option (A).

Explanation:

Oxidation : A chemical reaction in which addition of oxygen occurs or removal of hydrogen occurs is called oxidation.

Reduction:A chemical reaction in which elimination of oxygen occurs or addition of hydrogen occurs is called reduction.

In a given reaction,:

Hence,  is getting oxidized.

Hence, is getting reduced.

So, correct answer is option (A).

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
