unkown2

Thank you very much,all of you for helping me!!!

So its NH4NO3(aq)+NaOH(aq)->NH4OH+NaNO3? And one more question, MnO2 + 2H2O2 = O2 +2H2O + MnO2 and 2H2O2 +MnO2-> 2O2+2H2O+Mn which is correct?

Thanks you guys.After some time of hard research I got some answers now.Care to check them?You can just tell me which are wrong and I'll try fixing them up. 2HCL(aq) + Zn(s)-> H2(g)+ZnCl2(aq)-single replacement 2H2O2 +MnO2-> 2O2+2H2O+Mn-Decomposition? CuCl2(aq)+ Mg(s)->MgCl2(aq)+Cu(s)-single replacement NH4NO3(aq)+NaOH(aq)->NaNO3+NH3+H2O-double replacement Cu(NO3)2(aq)+Ni(s)->Cu(s)+Ni(NO3)2(aq)-single replacement AgNO3(aq)+NaCl(aq)->NaNO3(aq)+AgCl(s)-double replacement Ni(NO3)2(aq)+Cu(s)->Ni(s)+Cu(NO3)2(aq)-single replacement 2HCL(aq)+CaCO3(s)->CaCl2(aq)+H2O(l)+CO2(g)-double replacement

Hi,I need help on classifying chemical reactions. I must classify between a single replacement, double replacement, synthesis,and decomposition. I also need to complete the following equations. I basically know how to complete the equation if I knew what kind of reaction it is. Can anyone give me tips on how to recognize what kind of chemical reaction it is? HCL(aq) + Zn(s)-> H2O2 +MnO2-> I think that this is a double replacement. CuCl2(aq)+ Mg(s)-> NH4NO3(aq)+NaOH(aq)-> Cu(NO3)2(aq)+Ni(s)-> AgNO3(aq)+NaCl(aq)-> I think that this is a single replacement. Ni(NO3)2(aq)+Cu(s)-> HCL(aq)+CaCO3-> I need this on Monday so if anyone can help me till then it would be great.Thanks in advance.

Thank you to the guys that helped me. Wolfson- I am doing Science grade 10 and we are doing chemistry thats why I need help on the equation.(My teacher doesn't really teach us so we just to teach ourselves.And I need help so I asked it here) Thanks again!

Can someone give the balanced equations for these? sulfur dioxide + oxygen =sulfur trioxide methane + oxygen = carbon dioxide + water Aluminum chloride + pottasium = potassium chloride + aluminum ammonia gas + oxygen +nitrogen + water copper(II) oxide = copper + oxygen gas Thanks

I need help real bad on finding out which of these compounds,solid honey,lauric acid,epsom salt,and washing soda,are composed of ions and which are composed of molecules.Can anyone tell me?Also how and why? P.S it would be geat if anyone told me which compounds are electrolytes and non-electrolytes.
