Answer : 42.3 ml of a 0.266 M 
solution are required.
Solution : Given,
Molarity of solution 1 = 0.266 M
Molarity of solution 2 = 0.075 M
Volume of solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :
where,
= Molarity of solution 1
= Molarity of solution 2
= Volume of solution 1
= Volume of solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M solution are required.

<h3>What are decomposition reactions?</h3>
- Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
- When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
- When this happens the soluble compound such as ionic compounds ionizes to form ions.
- This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
- For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
Answer:
Of bond is formed by sharing of electrons - covalent
If bond is formed by donation and by accepting electrons - ionic bond
Bond formed between metals - metallic bond.
Chemical equations are to be balanced to be able to follow the law of conservation of mass where it says that mass cannot be created or destroyed. Reactions should be that the mass of the reactants is equal to the mass of the products.
