Given the balanced equation:2KI F2 → 2KF I2
Which type of chemical reaction does this equation represent?
(1) synthesis
(2) decomposition
(3) single replacement
(4) double replacement
Answers
Answer: Option (3) is the correct answer.
Explanation:
When a more reactive element or atom replaces a less reactive atom then this type of reaction is known as single displacement reaction.
In the given reaction, potassium iodide reacts with fluorine and results in the formation of potassium fluoride and iodine.
Here, fluorine being more reactive displaces iodine from potassium iodide.
Therefore, it is a single replacement or displacement reaction.
The given balanced equation represents a single replacement reaction.
What is a balanced equation?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Let's consider the following balanced equation.
2 KI + F₂ → 2 KF + I₂
Which type of chemical reaction does this equation represent?
- synthesis. No, since in a synthesis there is only one product.
- decomposition. No, since in a decomposition there is only one reactant.
- single replacement. Yes. Fluorine replaces iodine in potassium iodine.
- double replacement. No, since there is only one replacement.
The given balanced equation represents a single replacement reaction.

Final answer:
The decomposition of Nickel(II) hydroxide produces Nickel(II) oxide and water. The chemical equation is: Ni(OH)2 (s) → NiO (s) + H2O (l).
Explanation:
The decomposition reaction of Nickel(II) hydroxide into Nickel(II) oxide and water can be written as follows: Ni(OH)2 (s) → NiO (s) + H2O (l) . In this reaction, solid Nickel(II) hydroxide decomposes into solid Nickel(II) oxide and liquid water. It’s important to remember that in these reactions, a single, complex reactant breaks down into multiple, simpler products.

b)gains electrons and gains potential
c)energy gains electrons and loses potential energy
d)loses electrons and gains potential energy
Answers
Answer : The correct option is a) Loses electrons and loses potential energy.
Explanation :
Reducing agent : In a redox reaction, it is oxidized by the loss of electrons and by the loses of potential energy. It is also called as electron donor.
Reducing agent reduces others by loss of electron and its oxidation state increases.
For example : Sodium is a reducing agent and itself oxidized as follows,
Therefore, the molecule that function as a reducing agent in a redox reaction is loses electrons and loses potential energy.
Final answer:
In a redox reaction, the reducing agent loses both electrons and potential energy. This process results in oxidation of the reducing agent as the oxidation state of the reducing agent increases.
Explanation:
Oxidation-Reduction Reaction
In a redox or oxidation-reduction reaction, the molecule acting as the reducing agent (or electron donor) loses electrons and loses potential energy. Hence, the correct option is a). The reducing agent donates electrons to another substance or molecule and, in this process, is itself oxidized. The oxidation state of the reducing agent increases. The reduction process involves a gain of electrons, but this gain happens to the substance that receives the electrons, not the one who donates them (the reducing agent).

The stars when they release their helium and get rid of their cape and throw it into space is because it is already the end of their life
Explanation:
During a portion of its life, a bright star due to the thermonuclear fusion of hydrogen in helium in its nucleus, which releases energy that crosses the interior of the star and then radiates into outer space. When the hydrogen in the nucleus of a star is almost depleted, almost all heavier elements than naturally produced helium are created by stellar nucleosynthesis during the life of the star and, in some stars, by nucleosynthesis of supernovae when explode At the end of its life, a star can also contain degenerate matter
