balance the following equation: Aluminum+ sodium hydroxide +water gives sodium aluminate + hydrogen?
Panic room? Never watched it but kinda sounds like what it would be about
It's 'Panic Room' (2002) with Jodie Foster and Kirsten StuartThe 'boy' was actually Kirsten-Bella Cullen-Stuart ;) Hope it helps! ;)
in oxidation -reductioin reactions, one must balance the electrons taken lost , before you attempt balancing the atomsit is a matter of concept Al metal - Al+3 loses 3 electrons (an oxidation) H2O 's 2 H+'s take 2 electrons - H2 gas ( a reduction) you must have 3 Aluminums to lose 6 electrons, so that 3 waters can take 6 electrons - this gives the start: 2 Al 3 H2O NaOH - 2 NaAL(OH)4 3 H2 then you balance the NaOH: 2Al + 2NaOH + 6H2O 2NaAl(OH)4 + 3H2 that's your answer, electrons first in redox reactions
