PLZZ HELP ITS TIMED

Burning wood is a chemical reaction that requires oxygen. Sometimes people start a fire by lighting paper with a match and then blowing gently on the lit paper, Blowing on
the lit paper helps the reaction rate, or fire, go faster. Blowing on the lit paper moves more ait, which contains oxygen, over the reaction site

Which statement is true about why this works?

Blowing on fire reduces the temperature and increases reaction rate

Blowing on fire increases the concentration of oxygen and increases the reaction rate

Blowing on fire increases the temperature and increases reaction rate

Blowing on fire decreases the concentration of oxygen and increases the reaction rate

Answer 1

Answer:Carbon dioxide

Explanation:Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.

Next time you blow out a candle, think about what your breath is doing. Why do you think blowing on a candle flame makes it go out?
