Ammonia NH 3 chemically reacts with oxygen gas O 2 to produce nitric oxide NO and water H 2 O.

Hello everyone today. We have the following problem, soda lime and nitrogen dioxide can react according to the following reaction. This demonstrates how calcium hydroxide can be used to absorb nitrogen dioxide. Guess how many grams of calcium hydroxide are required to absorb 5.29 g of nitrogen dioxide. So first you want to start with what we were given, which was 5.29 g of nitrogen dioxide. We're going to multiply by a series of conversion factors in order to get two g of our calcium hydroxide. First, we're gonna multiply by the molar mass of our nitrogen dioxide, which according to the periodic table is 46. g of nitrogen nitrogen dioxide. We're then going to multiply by the multiple ratio, which if we look at our equation here, we have four moles over nitrogen dioxide and we have two moles of our calcium hydroxide. And lastly we're going to multiply by the molar mass of our calcium hydroxide. Which can be found on the periodic table by taking the masses of our calcium and our two hydrogen and two oxygen's and multiplying them and adding them together to give us 74.09 g of calcium hydroxide. Our units will cancel out And we will be left with 4.26 g of our calcium hydroxide as our final answer. And with that we have answered the question overall. I hope this helped. And until next time
