Question

The following is an example of what type of chemical reaction?
CH4 (g) + 2O2 (g) CO2 (g) + 2H2O (g)
Select one:
a. Single replacement
b. Decomposition
c. Double replacement
d. Combustion

Answer 1

Is there an = sign or ---> after the 2O2>

Answer 2

If so, it is a combustion reaction because the products are CO2 and water

Answer 3

Yes, there is a sign after the 2O2 sorry!! :O

Answer 4

Its ok!

Answer 5

I think the equation is :
\(CH_4 (g) + 2O_2 (g) \rightarrow CO_2 (g) + 2H_2 O (g) \)

Steven , as already mentioned by mikebmxer , you have to notice the products and identify the type of reaction with the help of them.

Answer 6

As the products are \(CO_2\) and \(H_2 O\) , it can be said that it is combustion reaction. You can also note the \(O_2\) there in the reactants side which means the reaction was carried on in the presence of oxygen . And oxygen is necessary for combustion. So it is combustion reaction.

Answer 7

Ok that makes much more sense! :)
I have another question for you, but let me try and figure it out first before I contact you. Thank you both for your fabulous help!

Answer 8

=)

Answer 9

Good attitude stevensde.

Answer 10

The following is an example of which type of chemical reaction?
Na (s) + H2O (l) ---> NaOH (aq) + H2 (g)


Alright, I'm feeding off of a hunch here. Is this a single replacement reaction?

Answer 11

Thank you Thoughts!

Answer 12

Yep you would be correct in calling this a single replacement

Answer 13

Sweet! hahaha :D Once again, thank you!

Answer 14

Anytime!
