Answer 2

It looks like you're trying to balance a chemical equation. The equation appears to start with sulfur (S) and proceed through several chemical reactions, ultimately leading to calcium sulfite (CaSO3). I'll help you balance this equation step by step.

Let's break down the reactions one by one:

1. S -> SO2 This is the combustion of sulfur to form sulfur dioxide. This reaction is already balanced as it is.

2. SO2 + Na2SO3 -> ??? We need to balance this reaction. First, let's write down the unbalanced equation:

SO2 + Na2SO3 -> ???

To balance it, you need to make sure that the same number of atoms of each element appears on both sides of the equation. Let's count the atoms:

• Sulfur (S): 1 on the left, 3 on the right
• Oxygen (O): 2 on the left, 4 on the right
• Sodium (Na): 2 on the right

To balance the equation, you can start by balancing the sulfur atoms first:

SO2 + Na2SO3 -> 3SO2 + Na2SO3

Now the sulfur atoms are balanced, but we need to balance the oxygen atoms. We can do this by adding coefficients in front of the compounds:

SO2 + Na2SO3 -> 3SO2 + Na2SO3 ^ ^ ^

Now the equation is balanced for sulfur and oxygen, but we need to balance the sodium atoms. You can do this by adjusting the coefficient in front of Na2SO3:

SO2 + Na2SO3 -> 3SO2 + 3Na2SO3

Now the equation is balanced with respect to all elements.

3. 3Na2SO3 -> CaSO3 This step seems to involve the conversion of sodium sulfite (Na2SO3) to calcium sulfite (CaSO3). To balance this, we need to make sure that the same number of atoms of each element appears on both sides of the equation:

On the left, we have:

• Sodium (Na): 6 atoms (3 molecules of Na2SO3)
• Sulfur (S): 3 atoms
• Oxygen (O): 9 atoms (3 molecules of Na2SO3)

On the right, we have:

• Calcium (Ca): 1 atom
• Sulfur (S): 1 atom
• Oxygen (O): 3 atoms

To balance this, you can write the equation as follows:

3Na2SO3 -> CaSO3 + 3Na2SO3

Now, the equation is balanced. The overall balanced equation for the entire reaction sequence is:

S -> SO2 + 3Na2SO3 -> CaSO3 + 3Na2SO3
