Which of the following is an example of a combustion reaction? A) Mixing of an acid and base
B) Photosynthesis in plants
C) Lighting of a Matchstick
D) Reacting sodium and chlorine

C) Lighting a matchstick

Explanation:

Mixing an acid and base will cause a neutralization reaction, a type of double displacement.

Photosynthesis is just a series of chemical reactions, but don't deal with the use of O2, but rather it's creation.

Reacting sodium and chlorine would make NaCl in a synthesis reaction.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

the answer is 303.15 or 303
