Question

Predict these reaction products. If a reaction takes place, balance the reaction if needed. If no reaction takes place then write no reaction.

Cu+FeCl3--->CuCl3 + Fe
Double replacement

Al+HBr---->

AgNO3 + KCL--->AgClKnO3
Double replacement

Ba(NO3)2+MgSO4---->BaSO4(s) +Mg(NO3)2(aq)
Double replacement

C8H18+O2

Can you let me know if I'm on track with the ones I did complete and help me with the ones I didn't?

Answers

Cu+FeCl3--->CuCl3 + Fe
Double replacement
<b> This reaction will not occur. First, if it did occur it would be a single replacement (you've replaced only one metal) and second, to occur the single element must be ABOVE the ion in the activity series. Cu is below Fe; therefore, no reaction.</b>

Al+HBr----> <b>AlBr3 + H2 and I'll let you balance it. Note that Al is ABOVE the ion (H^+) so a reaction WILL occur.</b>

AgNO3 + KCL--->AgClKnO3
Double replacement
<b>Looks ok if you add a + sign between the products.</b>

Ba(NO3)2+MgSO4---->BaSO4(s) +Mg(NO3)2(aq)
Double replacement
<b>Looks ok to me.</b>

<b>C8H18+O2 ==> CO2 + H2O and I'll let you balance it.</b>
