Question

Can anyone help me identify some reactions? I'm not very good with reactions >~<

Answer 1

Sure I can help! Don't worry that you're not very good with them, that's why you're doing these exercises to begin with, so you can learn them! =D

Answer 2

Awesome! Thank you :D The question says: Identify these reactions as synthesis, decomposition, single replacement, double replacement, or combustion. Then there is a list of reactions
2C2H6 + 7O2 --> 4CO2 + 6H2O
Ca + 2HCl --> CaCl2 + H2
2SO2 + O2 --> 2SO3

Answer 3

Identifying reactions really confuses me..I don't know how to tell all the different types apart

Answer 4

most reactions tend to follow a pattern, which is how we classify them

Answer 5

for example, a \(synthesis\) reaction always takes several reactants and combines them into a single product. Do you see one of those here?

Answer 6

The last one....?

Answer 7

Okay, I think I got it. I found a website that helped explain it a little...can someone check my answers?
1. decomposition
2. double replacement
3. synthesis

Answer 8

the first is not a decomp. A decomposition reaction looks like a synthesis reaction in reverse.

The first reaction takes a substance, combines it with oxygen, and produces carbon dioxide and water. That's a classic \(combustion\) reaction.

Answer 9

Ohhhhhhhhhhhhhh, okay! Yeah, I see that now lol. I don't know how I missed that the product is carbon dioxide and water. But other than that, everything is right?

Answer 10

the second isn't right, sorry

Answer 11

it's not a \(double\) replacement

Answer 12

Don't be sorry, I'm horrible with chemistry, totally not your fault =D So would it just be single replacement?

Answer 13

it is a single displacement. as a reactant, calcium is separate. it "replaces" the hydrogen in the product

Answer 14

Makes sense =)
