Answer: Option (d) is the correct answer.
Explanation:
A compound is defined as the substance in which only different atoms chemically combine together in a fixed ratio by mass.
For example, NaCl, HCl, , etc are all compounds.
Compounds are also pure substances like elements as they can be broken down into their constituent particles.
Whereas substances that are made up of only one type of atom are known as elements.
Thus, we can conclude that the most accurate description of compounds is that they are made up of atoms of 2 or more elements that are chemically combined.
Answer:
0.238 M
Explanation:
A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.
C₁.V₁ = C₂.V₂
C₁ × 24.00 mL = 0.220 M × 52.00 mL
C₁ = 0.477 M
The concentration of Pb(ClO₃)₂ is:
