​

Answer 1

Answer:

1st reaction= 4Na is oxidized and O2is reduced

2nd= H2 is oxidized and CuO is reduced

Answer 2

$\huge\purple{Required \: Answer :}$

In the reaction, $4</em></strong><strong><em>N</em></strong><strong><em>a + </em></strong><strong><em>O</em></strong><strong><em>_{2} \: -> 2 </em></strong><strong><em>N</em></strong><strong><em>a_{2}</em></strong><strong><em>O</em></strong><strong><em>$

4Na is Oxidised and O2 is Reduced

In the reaction, $</em></strong><strong><em>CuO</em></strong><strong><em> + </em></strong><strong><em>H</em></strong><strong><em>_{2} \: -> </em></strong><strong><em>C</em></strong><strong><em>u + </em></strong><strong><em>H</em></strong><strong><em>_{2}</em></strong><strong><em>O</em></strong><strong><em>$

Cu is Reduced and H2 is oxidised
