3NO2 + H2O + NO=?

3NO2(g) + H2O(l) → 2HNO3(aq) + NO(g) standard enthalpy: -133.5 Find the change in internal energy for this reaction.

dE = q + w

q = -133.5 but what are the units of delta H.

To find the balanced equation for the given chemical reaction, we need to consider the law of conservation of mass. This law states that the total mass of the reactants must be equal to the total mass of the products.

Let's break down the given chemical equation:
3NO2 + H2O + NO = ?

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's start by counting the number of atoms for each element.

On the left-hand side of the equation:
- Nitrogen (N): We have 3 nitrogen atoms from NO2 and 1 nitrogen atom from NO, so in total, we have 4 nitrogen atoms.
- Oxygen (O): We have 6 oxygen atoms from NO2 and 1 oxygen atom from H2O, so in total, we have 7 oxygen atoms.

Now, let's balance the equation by adding coefficients to the chemical formulae.

3NO2 + H2O + NO → 4NO + 2H2O

By adding coefficients, we ensure that the number of atoms on both sides of the equation is balanced.

Therefore, the balanced equation is:
3NO2 + H2O + NO → 4NO + 2H2O
