Both animals and plants rely on stored energy for survivalAnimals can store energy in the form of sugars from the consumption of other matter. Plants the other hand, utilize photosynthesis to produce sugar (glucose). Following storage, the sugars can then be used to provide energy for various functions within the organism. This is referred to as the burning of sugar shown in the chemical reaction below: C 6 H 12 O 6 (s)+O 2 (g) CO 2 (g)+H 2 O(g) 3. Complete the following questions based on the reaction above representing burning sugar: . Balance the chemical equation representing sugar burning (reaction above). b. What type of reaction(s) is/are being represented by the chemical reaction in part (a) ? . How would you prepare 40.00 of 0.250 M sugar solution (C 6 H 12 O 6 ) from a stock solution that is 1.25 M C 6 H 12 O 6 (aq)? ? Provide your answer in terms of of sugar stock solution and explain how you would dilute to the total volume. (HintHow many of sugar stock solution and how…
