Non-metal do not replace hydrogen from acid why?
because metal contain positive ions and hydrogen too
WHICH OF THE FOLLOWING WILL REPLACE HYDROGEN FROM ACIDS TO FORM SALTS?
Na
Why do metals replace hydrogen from acid but non metals do not?
This is because metals have positive ions and so does hydrogen. Hence the nature of their reactivity is same but the value of reactivity is different. Therefore metals replace hydrogen in a reaction while non metals dont...
When both -NH2 and -COOH replace hydrogen atoms on the same carbon atom and what is formed?
When both -NH2 and -COOH replace hydrogen atoms on the same carbon atom, an amino acid is formed.
Does sodium replace hydrogen in a single replacement reaction?
Yes, when sodium reacts with Hydrochloric acid it replaces the hydrogen as hydrogen gas. 2Na + 2HCl = 2NaCl + H2
Why does not silver evolve hydrogen on reacting with dilute sulphuric acid?
it is because, silver lies below hydrogen in electrochemical series. so it cannot reduce the hydrogen and replace it.
What gases are in an airship?
