The question is incomplete, the complete question is;
A 31 g sample of a compound that contains only the elements C,H and N is completely burned in O2 to produce 44.0 g of CO2, 45.0 g of H2O, and 92.0 g of NO2. Determine the empirical formula of the compound.
Answer:
CH5N2
Explanation:.
Mass of C = 44.0g/44.0 g/mol = 1 mol * 1 = 1 mole of C
Mass of H = 45.0 g/18 g/mol = 2.5 moles * 2 = 5 moles of H
Mass of N = 92.0 g/46 g/mol = 2 moles * 1 = 2 moles of N
Dividing through by the lowest mole ratio;
1/1, 5/1, 2/1
1 : 5 : 2
Hence the empirical formula is;
CH5N2

According to https://oureverydaylife.com/lemon-juice-stop-apples-browning-21624.html it days that"
Chemical Reaction
Once added to sliced apples, the ascorbic acid, or vitamin C, in lemon juice creates a barrier between the oxygen and the polyphenol oxidase. Until the lemon juice has evaporated or been completely absorbed, the oxygen reacts with the ascorbic acid, preventing the apple from turning brown".
1 millimeter (ml) is equal to 0.1 centimeters (cm), so all you have to do is take however many mm you have, and multiply that by 0.1. Then you have your answer. So, 59 times 0.1 is 5.9

Charle's law states that, v1 / t1 = v2 / t2 .
<span>Hence,v(volume) is directly proportional to t(temperature). </span>
<span>Thus, the volume decreases.</span>
