When glucose is consumed by humans, it reacts with oxygen in the body to produce carbon dioxide, water, and energy. how many grams of carbon dioxide would be produced if 45 grams of glucose completely react with oxygen? a. 1.5 gb. 1.8 gc. 11 gd. 66 g

The reaction of 45 g of glucose will produce 66 g of CO2

Explanation:

Here is the balanced equation:

C6H12O6+6O2→6CO2+6H2O

Since the molar mass of glucose is 180 g, the 45 g given mass in this problem is

no. of moles = 45g divided by 180g=0.25 mole

The equation tells us there are 6 moles of CO2 produced for each 1 mole of glucose that reacts. There fore, we will obtain

6×0.25=1.50moles of C6H12O6

Finally, converting to mass

1.50moles×44g mole

=66g

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
