Yes, because CO2 is carbon dioxide, and carbon dioxide contains molecules.
Answer:
Explanation:
Hello!
In this case, since the reactions between NaOH and the acids are:
Whereas we can see the 1:1 and 2:1 mole ratios between NaOH and HCl and H2SO4 respectively. In such a way, at the equivalence point we realize that:
Best regards!
Answer: Option (A) is the correct answer.
Explanation:
When there occurs no change in the chemical composition of a substance then it is known as physical property.
For example, mass, volume, density are all physical properties.
Since, the mass of an electron is negligible and an electron holds a negative charge.
Therefore, negatively charged particle with very little mass accurately describes the physical properties of electrons in atoms.
