C6H4(OH)2 + O2 -->

my answers

2HNO3 + Sr(OH)2 --> Sr(NO3)2 + 2H2O

2C6H4(OH)2 + 13O2 --> 12CO2 + 6H2O

Answer 1

Zn + Ni(NO3)2-->
AlCl3 + Na2CO3-->
Al + O2 -->
NO2 -->

please check these ones too thanks

Zn + Ni(NO3)2--> Zn(NO3)2 + Ni

AlCl3 + Na2CO3--> Al2(CO3)3 + 6NaCl
Al + O2 --> 2 Al2O3
NO2 --> O2N

Answer 2

The first two are OK.
Zn and Ni(NO3)2 is OK
AlCl3 and Na2CO3 is not correct. Al2(CO3)2 is not known to exist. It may form as an intermediate but the final product is Al(OH3)3 and CO2.
Al + O2 is OK
NO2 to form O2N is not correct.

Answer 3

thanks
