Answer:

C5H12 + O2 ---> CO2 + H20
B -> Combustion

Particles in which state of matter are the most likely to interact with each other to cause a chemical reaction?
B -> liquid

Identify this reaction

C + S8 ---> CS2

A -> Synthesis

3. Identify this reaction

Al + S2 ---> Al2S3
A -> Synthesis

Step-by-step explanation:

For the first question, you must remember that when you have a chemical reaction in which the products are CO2 (Carbon Dioxide) and H2O (water), you are examining a combustion reaction.

For the second question, the answer must be "liquid" because it is simply the easiest to use in a lab reaction. Solids tend to remain intact while liquids can easily mix, causing atoms to interact much more frequently. Atoms in gases are too spread out to be as likely to interact as in liquids.

For the third question, the answer must be "synthesis" because the simple combination of two reactants that results in a single product (maintaining the proper ratio outlined by its reactants) is a synthesis.

For the final question, the answer must also be "synthesis" for the same reasons as outlined in the previous reaction.
