The Si atom in SiF4
Which of the following aqueous solutions can be safely stored in a copper container?
NiCl2 NaBrAgNO3 HNO3HBr
please ask for options under the chart
2Fe(s) + 8HCl(aq) _____> 2HFeCl4(aq) + 3H2(g)
14HNO3(aq) + 3Cu2O(s) ____________ 6Cu(NO3)2(aq) + 2NO(g) + 7H2O(l)
Hg = +2
Si = +4
NaBr (correct)AgNO3 (notcorrect) HNO3(not correct)HBr (correct)
option A and B for first equation
option E and F for second equation
but u have to have only one answers and u said
