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

Answer:
Q8) True
Q9) First ionization energy
Q10) Metal oxides
Explanation:
A common property of group one elements (alkali metals) is their combination with water to form basic solutions. E.g 2K(s)+2H2O(l)→2KOH(aq)+H2(g).
The distance of the outermost electron in the atom from the nucleus is inversely related to the first ionization energy. As the distance between the outermost electron and the nucleus in group 17 elements gets larger, the corresponding first ionization energies of elements in the group gets smaller.
Group 1 elements can combine with oxygen to give metal oxides. E.g 4K + O2 --> 2 K2O
Hello!
To solve this question, we need to use the
Avogadro's Number, which is a constant first discovered by
Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are
6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:
So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent
14,12 moles of Na₂SO₃
Have a nice day!
Answer:
the cycle of water and how it evaporates with energy from the sun and the droplets are stored in clouds which is condensation and when it rains or snows those are forms of precipitation
