Question

Which of the following are redox reactions? for those that are, indicate which element is oxidized and which is reduced. for those that are not, indicate whether they are precipitation or acid-base reactions.
a) Cu(OH)2(s) + 2 HNO3 (aq) = Cu(NO3)2(aq) + 2 H2O (l)
b) Fe2O3 (s) + 3 CO(g) = 2 Fe (s)+ 3 CO2(g)
C) Sr(NO3)2(aq) + H2SO4(aq)= SrSO4 (S)+ 2HNO3(aq)
d) 4Zn(s)+10H(aq)+2NO3(aq)= 4Zn(aq)+N2O(g) + 5H2O (l)

Answer 1

i do nto know the difference between the preciptation equation and acid-base equation

Answer 2

just learned this if it is an acid base equation if it is a strong acid is completely ionizes and thats all i know lol

Answer 3

it*

Answer 4

so can u help me with knowing which is an acid base equaiton

Answer 5

A?

Answer 6

precipitation produces a solid

Answer 7

so b and s are preciptaion reactions ??

Answer 8

i think B is a redox

Answer 9

ok then thanku
