What is the formula equation and balance it and also give the sum coefficient of:

1.sulfur dioxide(g)+oxygen(g)delta arrow (sorry i can't draw it here) sulfur trioxide
2. nitrogen dioxide(g)+dihydrogen monoxygen(l)- nitric acid(g)+nitrogen monoxide

Sure you can draw an arrow. --> or ==> or >>>

S + O2 ==> SO3. You balance and add phases.
NO2 + H2O ==> HNO2 + NO You balance and add phases.

To balance a chemical equation, you need to ensure that there is an equal number of atoms of each element on both sides of the equation. Here are the balanced equations for the two reactions you provided:

1. Sulfur dioxide (g) + Oxygen (g) → Sulfur trioxide (g)
To balance this equation:
- Start by counting the number of atoms of each element on both sides.
On the left side, we have 1 sulfur and 2 oxygen atoms.
On the right side, there is 1 sulfur and 3 oxygen atoms.
- To balance the sulfur atoms, place a coefficient of 1 in front of the sulfur dioxide:
1 SO2 + Oxygen (g) → Sulfur trioxide (g)
- Now, there are 2 sulfur atoms on the right side.
- To balance the oxygen atoms, place a coefficient of 1.5 in front of the oxygen:
1 SO2 + 1.5 O2 → 1 SO3
- Multiply through by 2 to eliminate the decimal coefficients:
2 SO2 + 3 O2 → 2 SO3
The sum of the coefficients is 2 + 3 + 2 + 3 = 10.

2. Nitrogen dioxide (g) + Dihydrogen monoxygen (l) → Nitric acid (g) + Nitrogen monoxide (g)
To balance this equation:
- Start by counting the number of atoms of each element on both sides.
On the left side, there is 1 nitrogen, 2 oxygen, and 2 hydrogen atoms.
On the right side, there is 1 nitrogen, 1 oxygen, and 2 hydrogen atoms.
- To balance the nitrogen atoms, no coefficient is necessary as there is already 1 nitrogen on both sides.
- To balance the oxygen atoms, place a coefficient of 2 in front of the nitric acid:
Nitrogen dioxide (g) + Dihydrogen monoxygen (l) → 2 Nitric acid (g) + Nitrogen monoxide (g)
- Now, we have 4 oxygen atoms on the right side.
- To balance the hydrogen atoms, place a coefficient of 2 in front of the dihydrogen monoxygen:
Nitrogen dioxide (g) + 2 Dihydrogen monoxygen (l) → 2 Nitric acid (g) + Nitrogen monoxide (g)
The sum of the coefficients is 1 + 2 + 2 + 2 + 2 = 9.
