How many milliliters of NH3 (at STP) are needed to react with 45.0 mL of NO2 (at STP) according to the equation.

Can someone please... help me?

a) 45.0 mL
b) 27.5 mL
c) 33.8 mL
d) 60.0 mL

IT depends on the reaction. If you are interested in this one,

NH3 + NO2 >> NH2 + HONO

Then they react on a one to one ratio, or a) is the anwer, and it doesn't matter if it is at STP or not.

To find out how many milliliters of NH3 are needed to react with 45.0 mL of NO2, we need to determine the stoichiometry of the reaction. The balanced equation will help us with this.

Unfortunately, the equation you mentioned is missing, so we cannot provide a definitive answer. However, I can guide you on how to find the answer once you have the balanced equation.

Here are the steps to follow:

1. Write the balanced equation for the reaction. For example, let's assume the balanced equation is:

2 NH3 + 3 NO2 → 4 N2 + 6 H2O

2. Determine the stoichiometric ratio between NH3 and NO2 based on the balanced equation. In this example, it is 2:3, which means 2 moles of NH3 react with 3 moles of NO2.

3. Convert the given quantity of NO2 (45.0 mL) to moles. To do this, you need to know the molar volume of an ideal gas at standard temperature and pressure (STP), which is 22.4 L/mol.

Number of moles of NO2 = (Volume of NO2 at STP) / (Molar volume at STP)
= 45.0 mL / 1000 mL (1 L / 1000 mL) / 22.4 L/mol

4. Use the stoichiometric ratio from step 2 to determine the number of moles of NH3 needed. In this example, the ratio is 2:3, so you multiply the number of moles of NO2 by (2/3):

Number of moles of NH3 = Number of moles of NO2 × (2/3)

5. Finally, convert the moles of NH3 back to milliliters using the molar volume at STP:

Volume of NH3 = Number of moles of NH3 × (Molar volume at STP)

Once you have the volume of NH3 in milliliters, you can compare it to the given options (a), b), c), d)) to find the closest answer.

Remember, without the balanced equation, we cannot determine the correct answer. Make sure you have the complete equation before proceeding with the steps mentioned above.
