150 g of an unknown liquid is heated with 24,975 kj of heat to form 0°c to 75°c. identify the unknown liquid.

substance c (j/g-°c)
water (ice) 2.05
ammonia (liquid) 4.70
ethanol 2.44
gasoline 2.22
water (liquid) 4.18
water (vapour) 2.08

a. water
b. ethanol
c. ammonia
d. gasoline < -- ? ?

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.

i think   the answer is c hope i'm right

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
