Balance the following equations:

A. N2O>N2+O2
B. HBr>H2+Br2
C. CH4+O2>CO2+H2O

The easiest way is trial and error.

2N2O ==> 2N2 + O2

Sure, I can help you balance these chemical equations. Balancing equations involves making sure that there is an equal number of atoms on both sides of the equation. Here's how you can balance each of these equations:

A. N2O > N2 + O2
To balance this equation, you start by looking at the individual elements. Let's begin with nitrogen (N). On the left side, we have 2 nitrogen atoms in the N2O molecule, while on the right side, we have 2 nitrogen atoms in the N2 molecule. So, the nitrogen is already balanced.

Next, let's consider oxygen (O). On the left side, we have 1 oxygen atom in the N2O molecule, while on the right side, we have 2 oxygen atoms in the O2 molecule. To balance oxygen, we need to have the same number of oxygen atoms on both sides. To do this, we multiply the N2O molecule by 2 to get:

2N2O > N2 + 2O2

Now nitrogen and oxygen are balanced, and the equation is balanced.

B. HBr > H2 + Br2
To balance this equation, let's start with hydrogen (H). On the left side, we have 1 hydrogen atom in the HBr molecule, while on the right side, we have 2 hydrogen atoms in the H2 molecule. So, we need to multiply the HBr molecule by 2 to balance hydrogen:

2HBr > H2 + Br2

Next, let's consider bromine (Br). On the left side, we have 1 bromine atom in the HBr molecule, while on the right side, we have 2 bromine atoms in the Br2 molecule. To balance bromine, we need to have the same number of bromine atoms on both sides. To do this, we multiply the Br2 molecule by 2 to get:

2HBr > H2 + 2Br2

Now both hydrogen and bromine are balanced, and the equation is balanced.

C. CH4 + O2 > CO2 + H2O
To balance this equation, let's start with carbon (C). On the left side, we have 1 carbon atom in the CH4 molecule, while on the right side, we have 1 carbon atom in the CO2 molecule. So, the carbon is already balanced.

Next, let's consider hydrogen (H). On the left side, we have 4 hydrogen atoms in the CH4 molecule, while on the right side, we have 2 hydrogen atoms in the H2O molecule. To balance hydrogen, we need to multiply the H2O molecule by 2 to get:

CH4 + O2 > CO2 + 2H2O

Finally, let's consider oxygen (O). On the left side, we have 2 oxygen atoms in the O2 molecule, while on the right side, we have 2 oxygen atoms in the CO2 molecule and 4 oxygen atoms in the 2H2O molecules. To balance oxygen, we need to multiply the O2 molecule by 2 to get:

CH4 + 2O2 > CO2 + 2H2O

Now carbon, hydrogen, and oxygen are all balanced, and the equation is balanced.
