1. Plastic surgery (Used mostly by both genders to fill in the missing spots they have on/in their body or increase the size or decrease depending on whatever you want the doctor to do for you)

2. Plastic water bottles (Normal containers that we should recycle more and also are used to hold/store our water in to hold it for use while we drink, like a mobile water fountain)

3. Plastic Trumpet (Used to show younger children how to play the real instrument, like a preview of it).

Enter a balanced equation for the complete combustion of liquid C3H7OH. Express your answer as a chemical equation. Identify all
Vlad1618 [11]

2 C₃H₇OH (l) +  9 O₂ (g) → 6 CO₂ (g) + 8 H₂O (g)

Explanation:

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

Bellow we have the balanced chemical equation of the complete combustion of C₃H₇OH:

C₃H₇OH (l) +  (9/2) O₂ (g) → 3 CO₂ (g) + 4 H₂O (g)

to have integer coefficients  we multiply the reaction with 2:

2 C₃H₇OH (l) +  9 O₂ (g) → 6 CO₂ (g) + 8 H₂O (g)

where:

(l) - liquid

(g) - gaseous
