An alkali metal A givesses acompound B (moleculare mass=40)on reacting

1.	An alkali metal A givesses acompound B (moleculare mass=40)on reacting with water. Thecompound B Gues a solublecombound c on treatment withaluminium oxide Identify A, Band c and gives the reaction
Answer» Answer: A is SODIUM because molar mass of NaOH is 40; which can be SHOWN as follows: Na(23)+O(16)+H(I)=40 So. B is NaOH When sodium HYDROXIDE is TREATED with ALUMINIUM oxide, we get sodium aluminate. So, C is sodium aluminate. Following reaction happens in this case: Al²0³+2NaA1O²+H²O

Answer:

A is SODIUM because molar mass of NaOH is 40; which can be SHOWN as follows:

Na(23)+O(16)+H(I)=40

So. B is NaOH

When sodium HYDROXIDE is TREATED with ALUMINIUM oxide, we get sodium aluminate. So, C is sodium aluminate. Following reaction happens in this case:

Al²0³+2NaA1O²+H²O
