The oxidation state for carbon element in co2 is:
a. +4
b. +5
c. +1
d. +3

Option A,+4

Explanation:

Oxidation state of any element is the sum of oxidation of all elements =0

Here we need to find oxidation no of carbon and consider oxidation no of carbon as X and oxidation number of oxygen is -2

Then X+2(-2)=0 (since 2 oxygen atoms are there in CO2 )

X-4=0

X=+4

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
