Hydrogen combines with chlorine to form HCL. It also combines with sodium to form NaH. If sodium and chlorine combine with each other, they will do so in the ratio of their masses as Correct Answer 23 : 35.5
Concept:
- Hydrogen has an atomic no. 1 and a mass of 1.
- Hydrogen is a first group element.
- Chlorine has atomic no. 17 and a mass of 35.5.
- Chlorine belongs to group 17 (halogen family).
- Sodium (Na) has atomic no. 11 and a mass of 23
- Sodium belongs to the first group of alkali metals.
Explanation:
- In order to combine and form HCl, one molecule of hydrogen gas and chlorine gas is combined to give 2 molecules of HCl.
- H2 + Cl2 → 2 HCl i.e. in the ratio of 1:1:2
- In terms of mass, the ratio is 1: 35.5: 36.5
- Similarly, when Sodium atom combines with hydrogen it is in the ratio of 1: 1 and mass ratio of 23:1
- Na + H → NaH
- When sodium combines with Chlorine it forms NaCl.
- Na + Cl → NaCl
- The ratio is 1: 1 and the mass ratio is 23: 35.5
- So, the correct option is 1
Additional Information
- NaCl is commonly known as common salt.
- Its molar mass is 58.5
- It is readily soluble in water.
