Question

Given the incomplete equation representing a reaction:

2Na(s) + 2H2O() → 2Na+(aq) + 2 _____ (aq) + H2(g)

What is the formula of the missing product

Answer 1

Answer:It's OH-

Step-by-step explanation:

Answer 2

Answer : The formula of the missing product is,
`OH^_`

Explanation :

The given incomplete equation representing a reaction,

`2Na(s)+2H_2O(l)\rightarrow 2Na^+(aq)+2__(aq)+H_2(g)`

When the sodium metal react with the water then it gives a colorless solution of sodium hydroxide and hydrogen gas. In the solution, sodium hydroxide is present in the form of ions i.e,
`Na^+` and
`OH^-` ions.

The balanced chemical reaction will be,

`2Na(s)+2H_2O(l)\rightarrow 2Na^+(aq)+2OH^-(aq)+H_2(g)`

Therefore, the formula of the missing product is,
`OH^_`
