in My book i studied a activity i saw that -
1.)2Na + 2H2O = 2NaOH + H2
2.)Zn + H2O = ZnO + H2
IN YTHE FIRST EQUATION IN MY BOOK THEY SHOWED A ARROW POINTING UPWARDS AFTER H2
BUT IN SECOND EQUAION THEY DID NOT SHOW ARROW PINTING UPWARDS AFTER H2
CAN OU STATET THE RESON FOR THIS. AND ALSO TELL THAT IF WE BRING A BURNING MATCHSTICK NEAR THE SECOND RECTION WILL THE MATCHSTCK BURN WITH A POP SOUND?
