An oxidant or oxidizing agent is the substance in the redox reaction which undergoes reduction. Reduction occurs when the substance's charge has lowered after the reaction.The other process where the charge increases is called oxidtion.
(B) Copper (II) sulfite has the chemical formula CuSO3.
Copper(II) sulfate is the chemical compound CuSO4, although it is also known as blue vitriol, Roman vitriol, the vitriol of copper, and bluestone. Copper sulfate is most frequently found as its pentahydrate, which has the chemical formula CuSO4. 5H2O.
For further information on the chemical name of the compound cu2co3, see its chemical formula. This compound is made up of copper cations (Cu2 ) and carbonate anions (CO3), and as a result is known as copper carbonate and is categorized as a salt.
CuCO is the chemical formula for copper(II) carbonate, also known as cupric carbonate. It is an ionic solid (a salt) that, at room temperature, consists of

Answer:
option d = 3.125 g
Explanation:
Given data:
Mass of chemical = 100 g
Half life = 8 days
mass left after 40 days = ?
Solution:
First of all we will calculate the total half life's,
half life's = T (elapsed) / T half life
half life's = 40 / 8 = 5
starting mass = 100 g
half life's 1 2 3 4 5
Mass 100/2 50/2 25/2 12.5/2 6.25/2
50 g 25 g 12.5 g 6.25 g 3.125 g
Answer:
I₂ + H₂O --------→ HI + HIO
Explanation:
Iodine is not fully dissolve in water but only dissolve up to some extent.
When iodine was mixed with water it give mixture of two products.
- Hydrogen iodide or hydroiodic acid (HI)
- Hypoiodous acid (HIO)
So the balance reaction is as under
I₂ + H₂O --------→ HI + HIO
All the reactant are one mole and one one mole of each product produced in the shown reaction.
This is a reversible reaction and only 0.05% of Iodine molecule react with water and the other Iodine molecule remain in water unreacted.
