Accepted Answer

Welcome back everyone. We need to give the products and bounced molecular equation for the reaction of liquid methanol with nitrogen dioxide gas. If there's no reaction, we're going to write no reaction. Let's begin by writing out what are chemical formulas look like. We have methanol CH 30. H, which is told to be in liquid form according to the prompt reacting with nitrogen dioxide gas N. 02. And as as the type of reaction, we want to recognize that this liquid is going to be displaced or decomposed into the following products. Where we have carbon dioxide gas form, we have water vapor form So H 20 with a gas label and then we have nitrogen gas form these are our three products. And we should recognize that this reaction is a gas evolution reaction. So now with our full reaction right now, we need to ensure that this is balanced. So we're going to compare our product and react inside to one another based on the number of atoms we have beginning with carbon on both sides. And actually let's just write out all of our atoms. We have carbon, hydrogen, nitrogen and oxygen to consider on both sides of our equation. So beginning with our reacting side, we have one atom or one mole of carbon total on the reactant side. Then considering our hydrogen atoms, we have 34 atoms of hydrogen on our reactant side. Looking at oxygen, we have 123, so three moles of oxygen on the reactant side total. And then for nitrogen on the reactant side, we just have one mole Now, for carbon on the product side, we also have one mole for hydrogen on the product side, we have two moles of hydrogen for nitrogen on the product side of our reaction, we have two moles. And for oxygen on the product side, we also have three moles. Now when it comes to bouncing equations try to bounce the non oxygen and non hydrogen atoms. First, we see that our carbon atoms are balanced, but our nitrogen atom is not. So we can begin by bouncing out nitrogen on the reacting side with nitrogen on the product side by placing a coefficient of three in front of nitrogen on the product side, which would give us six moles of nitrogen and then placing a coefficient of six in front of our nitrogen dioxide gas on the reactant side. To give us six moles of nitrogen on the reactant side, meaning our nitrogen are balanced. But now we have changed the number of oxygen's on the reactant side, which now gives us a total of 13. Oxygen's on the react inside. So we're going to mend this by increasing our number of oxygen on the product side, where if we were to place a coefficient of eight in front of our water and a coefficient of four in front of our carbon dioxide on our product side. That would give us eight plus eight, which would give us 16 moles of oxygen on the product side. And so now we just want to increase our oxygen on the reactant side from 13 to 16, We can do so by placing a coefficient of four in front of our methanol reactant. This will now give us a total of four plus 12, which would give us 16 moles of oxygen on the reactant side and would also change our carbon and hydrogen. So our carbon on the reacting side will now be four moles of carbon, which will also match the four moles of carbon on our product side. From that coefficient of four in front of carbon dioxide. And then for hydrogen we would have a total of four times three, which would be 12 plus four for hydrogen, which would give us 16 moles of hydrogen on the react inside and on the product side we can count a total of also eight times to being moles of hydrogen on the product side. And so as you can see with these coefficients that we've added, we can now confirm that our equation is fully balanced. So this would be our balanced molecular equation for the gas evolution of liquid methanol and nitrogen dioxide gas. So what's highlighted in yellow represents our final answers where we have our products and our balanced molecular equation, our products here written below and then are balanced molecular equation. So this will all correspond to choice be in the multiple choice as the correct answer. I hope that this made sense. And let us know if you have any questions.
