Answer:
B.) the number of protons and also the number of electrons in an element
Answer: Molecular mass of is 82 g
Explanation:
Molecular mass (M) is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
Atomic Mass of Carbon (C) = 12 g
Atomic Mass of hydrogen (H) = 1 g
Atomic Mass of oxygen (O) = 16 g
Atomic Mass of sodium (Na) = 23 g
Molecular mass of = 12(1)+1(3)+12(1)+16(2)+23(1) = 82 g
The solid product from reaction of sulfuric acid with sucrose is?

<h3>RELATED TO THE QUESTION </h3>
- <u>Solid is one of the four fundamental states of matter</u>. The molecules in a solid are closely packed together and contain the least amount of kinetic energy.
- <u>A solid is characterized by structural rigidity and resistance to a force applied to the surface</u>.
- <u>Sulfuric acid or sulphuric acid, also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen</u>, with molecular formula H₂SO₄. It is a colorless, odorless and viscous liquid that is miscible with water at all concentrations.
- <u>Sucrose is common sugar. It is a disaccharide</u>, a molecule composed of two monosaccharides: glucose and fructose. Sucrose is produced naturally in plants, from which table sugar is refined. It has the molecular formula C₁₂H₂₂O₁₁.

Answer:
Oxidation state of S in SO3^2- is +4
Explanation:
S in SO3^2-=
S = ?
O = -2
S + 3 moles of O * -2 = -2
S + (-6) = -2( it has charge -2)
S - 6 = -2
S = -2 + 6
S = +4
Note, the sign is very important
Don't confuse SO3 together with SO3^2-, the oxidation state of S in SO3 is + 6, how?
S = ?
O = -2
S + 3 * -2 = 0 ( because it has no charge)
S - 6 = 0
S = +6
And in SO3^2-
S = +4
The difference is that one has charge SO3^2- and the other doesn't SO3.
Answer:
in my opinion the answer is A
