Question

YRR PLS HELP it is urgent...^-^​

Answer 1

Answer:

1)=Au+O2=Au O2

2)=Al+N2=ALN

3)=No reaction

4)=Here, NaOH might melt

5)=No reaction

Explanation:

1)=This is a redox(Oxidation-reduction) reaction.

2)=Here, Alimunium rwacts with Nitrogen to form its Nitride.

3)=Here, reaction would not take place as Copper's position is below of Hydrogen in the reactivity series and so, Copper is an unreactive or very less reactive metal.

4)=Here, exothermic reaction takes place and so, NaOH is can absorb water vapour and so warms releasing energy in the form of heat.

5)=Agcl +NaNO3 would not react because here is already a reaction which is displacement reaction.

And moreover, Ag is more reactive than NaNo3, so here all would be constant and do not react.

I hope these answers would be ample precise and help you,

Thank you.
