I really really need help with my homework. It's for points and I don't wanna fail, but I don't understand it at all.

I need to identify the type of reaction, predict the products, and balance the equations. Show work.

Please help

I Really Really Need Help With My Homework Its For Points And I Dont Wanna Fail But I Dont Understand It At All I Need To Identify The Type Of Reaction Predict class=

Sagot :

Answer:

Below!

Explanation:

27) Mg + HCl = MgCl2 + H2

This would be a single replacement/displacement

Balanced equation : Mg + 2HCl = MgCl2 + H2

28) KBr + Cl2 = KCl + Br2

This would be a single replacement/displacement

Balanced equation : 2KBr + Cl2 = 2KCl + Br2

29) FeS + HCl = FeCl2 + H2S

This would be a double replacement/displacement

Balanced equation : FeS + 2HCl = FeCl2 + H2S

30) KI + Pb(NO3)2 = PbI2 + KNO3

This would be a double replacement/displacement

Balanced equation :  2KI + Pb(NO3)2 = PbI2 + 2KNO3

I took chem last semester and honestly I didn't understand this either, but yt videos really helped me! I can't post links here but if you just search up "How to predict the products of chemical equations" and "how to balance", I really recommend the channel named "The organic chemistry tutor".

Here is how to determine type of reaction

Synthesis : A + B = AB

Decomposition : AB = A + B

Single replacement : AB + C = AC + B

Double replacement : AB + CD = AC + BD

^A,B,C, and D represent elements
