This chemical reaction is balanced.

Question

This chemical reaction is balanced.

2CO2 + 1H2O → 1C2H2 + 3O2
A true
B. False

Answer 1

To determine if the chemical reaction is balanced, we need to check whether there is an equal number of each type of atom on both sides of the reaction.

Let's start by counting the number of atoms for each element on both sides of the reaction:

Carbon (C):
- Left side: 2 atoms of C
- Right side: 2 atoms of C

Hydrogen (H):
- Left side: 2 atoms of H
- Right side: 0 atoms of H

Oxygen (O):
- Left side: 4 atoms of O
- Right side: 8 atoms of O

Based on our counts, we can see that the number of carbon and oxygen atoms is balanced. However, the number of hydrogen atoms is not the same on both sides of the reaction.

Therefore, the statement "This chemical reaction is balanced" is false (Choice B).

Answer 2

B. False

The given chemical reaction is not balanced. In order to balance it, we need the same number of atoms for each element on both sides of the equation.

Let's balance the chemical reaction step by step:

2CO2 + 1H2O → 1C2H2 + 3O2

First, let's balance the carbon (C) atoms on both sides of the equation. On the left side, we have 2 CO2, which means there are 2 carbon atoms. On the right side, we have 1 C2H2, which means there are 2 carbon atoms as well. So, the carbon atoms are already balanced.

Next, let's balance the hydrogen (H) atoms. On the left side, we have 1 H2O, which means there are 2 hydrogen atoms. On the right side, we have 1 C2H2, which means there are 2 hydrogen atoms as well. So, the hydrogen atoms are already balanced.

Finally, let's balance the oxygen (O) atoms. On the left side, we have 2 CO2 and 1 H2O, which means we have a total of (2x2) + 1 = 5 oxygen atoms. On the right side, we have 3 O2, which means we have a total of 2x3 = 6 oxygen atoms. So, the oxygen atoms are not balanced.

To balance the oxygen atoms, we need to put a coefficient of 5 in front of the O2 on the right side:

2CO2 + 1H2O → 1C2H2 + 5O2

Now the chemical reaction is balanced since we have the same number of atoms for each element on both sides of the equation.
