What type of reaction is depicted by this equation?

2C4H10(g)+13O2(g)–>8CO2(g)+10H2o(g)

A.) Combustion.

B.) Single- replacement.

C.) Combination.

D.) Decomposition.

Can you also explain how to do this in VERY simple terms please? I am slow at understanding things.

Thanks!

Combustion. It releases carbon dioxide and water and energy

For a combination reaction, I think only one molecule is created such as Na + Cl–> NaCl

Or O 2 + 2H 2 O → 2H 2 O 2

Single replacement reaction-> A+BC–> AC+B

Decomposition–> AB–>A+B or NaCl–> Na +Cl
I’d go for Combustion, since combustion by definition is reaction where fuel (C4H10) reacts with oxidant (O2), heat is released (that could be noted above the –>, np if it isn’t) and complete chemical conversion. That’s what happens in the equation.

It’s not combination or decomposition, since there is cross-replacement of moleculaes (se, there is nothing composed from elements and nothing decomposed to elements)

It’s not single-replacement, since that would require one element (or ion) passing into compound.
A) Combustion because Carbon dioxide and water are the end products of burning!
