Which of the following equations is balanced correctly?

A. 2 C3H3 + O2 → 2 CO2 + H2O
B. Cl2 + 2 KBr → KCl + Br2
C. 3 H2O → H2 + 3 O2
D. 2 C2H2 + 5 O2 → 4 CO2 + 2 H2O

Can anyone help me figure out which is balanced correctly?

Never mind I figured out it was D

Its A

Its is D i know it is

the one with the same number of atoms of each element on both sides

just count the various types of atoms on either side of the arrow

you are all crazy it is c

its b tust me the real answer is b

Certainly! Balancing chemical equations can be done by ensuring that there is an equal number of atoms on both sides of the equation.

Let's analyze each option and check if it is correctly balanced:

A. 2 C3H3 + O2 → 2 CO2 + H2O
Checking the number of Carbon (C) atoms:
Left side: 2 * 3 = 6
Right side: 2 * 1 = 2
Since the number of Carbon atoms is not balanced, we can eliminate this option.

B. Cl2 + 2 KBr → KCl + Br2
Checking the number of Bromine (Br) atoms:
Left side: 2 * 1 = 2
Right side: 1
Since the number of Bromine atoms is not balanced, we can eliminate this option.

C. 3 H2O → H2 + 3 O2
Checking the number of Hydrogen (H) atoms:
Left side: 3 * 2 = 6
Right side: 2
Since the number of Hydrogen atoms is not balanced, we can eliminate this option.

D. 2 C2H2 + 5 O2 → 4 CO2 + 2 H2O
Checking the number of Carbon (C) atoms:
Left side: 2 * 2 = 4
Right side: 4
Checking the number of Hydrogen (H) atoms:
Left side: 2 * 2 = 4
Right side: 2 * 2 = 4
Checking the number of Oxygen (O) atoms:
Left side: 5 * 2 = 10
Right side: 4 + (2 * 2) = 8
Since all the atoms are balanced on both sides, this equation is correctly balanced.

Therefore, the correct answer is option D.
