The empirical formula is N₂O₅.
The empirical formula is the <em>simplest whole-number ratio of atoms</em> in a compound.
The ratio of atoms is the same as the ratio of moles, so our job is to calculate the <em>molar ratio of N:O</em>.
I like to summarize the calculations in a table.
<u>Element</u> <u>Moles</u> <u>Ratio¹ </u> <u> ×2² </u> <u>Integers</u>³
N 1.85 1 2 2
O 4.63 2.503 5.005 5
¹To get the molar ratio, you divide each number of moles by the smallest number (1.85).
²Multiply these values by a number (2) that makes the numbers in the ratio close to integers.
³Round off the number in the ratio to integers (2 and 5).
The empirical formula is N₂O₅.
Answer:
PART B
1. Polysaccharide
2.Carbohydrates
3. DISACCHARIDE
4. Monosaccharide
PART A
2 is incorrect
Explanation:
PART A
The option 2 is incorrect because it is not in all carbohydrates that the number of atoms of carbon will be equal to the number of atoms of oxygen. This can be seen in the case of sucrose with the molecular formula C12H22O11
PART B
1. A carbohydrate that yields many monosaccharides when hydrolysed is a polysaccharides
2. The general name of any sugar is carbohydrate
3. Lactose is a double sugar meaning it contains 2 monosaccharides or simple sugar and thus when hydrolysed would be splitted into two simple sugars
4. A monosaccharide cannot be hydrolysed further because it’s at the simplest stage of any carbohydrate
Ra-226 will go through α decay which means the nucleus of radium-226 will emit a α particle. α particle consists of 2 protons and 2 neutrons. So it will become Rn-222.
