Please help me what is the ionic equation for AgNO3(aq) + Na3PO4(aq)? Not sure what I'm doing wrong here is what I have so far 3Na^+(aq) + PO_4^-3(aq) + 3Ag^+(aq) +3NO^3-(aq) --> 3Na^+(aq) + 3NO^3-(aq) + Ag_3PO_4(s)
I'm not sure what I'm doing wrong it still says oxidation state is improper and no the spaces do not matter
What is the complete ionic equation for NaOH(aq) + Fe(NO3)3(aq)? I'm putting this on webassign, but it's telling me "One or more of your reactants appear to have an improper oxidation state. One or more of your products contains an improper oxidation state. 3Na^+ ...
Please please help!!!!! Solve the inequality and write the solution set in interval notation 4x^3 -6x^2<0 2x^2 (2x-3)<0 2x-3<0 x= 3/2 Now I'm not sure about this 2x^2<0 x^2<1/2 sq root of x^2<sq root of 1/2 x=.7071 Right? When I plug it in the calculator ...
