Answer:
C2H5OH is a formula of ethyl alchol or ethanol.
alkenes are characterisized by carbon-carbon double bond.
burning is an example of exothermic reaction
atomic number of element is x the symbol of its ion is +1 bcz it will lose one electron
if temperature increases then rate of chemical reaction increases
Explanation:
i hope this will help you :)

A) The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion.
b) Gaseous particles tend to undergo diffusion because they have kinetic energy.
Answer:
The balanced half-reaction in which sulfate ion is reduced to sulfite ion is a two electron process
Explanation:
In the sulfate anion, S, acts with +6 in the oxidation number
SO₄⁻²
This is the anion from the sulfuric acid, when it lost the 2 protons
H₂SO₄ → 2H⁺ + SO₄⁻²
In the sulfite anion, S, acts with +4 in the oxidation number.
SO₃⁻²
This is the anion, generated when the sulfurose acid lost the 2 protons.
H₂SO₃ → SO₃⁻² + 2H⁺
In acidic medium
2H⁺ + SO₄⁻² + 2e⁻ → SO₃⁻² + H₂O
In basic medium
H₂O + SO₄⁻² + 2e⁻ → SO₃⁻² + 2OH⁻
