Accepted Answer

Hello everyone today, we are being given the following problem, identify the following as combustion precipitation or dis propose Shia Nation. So the first thing I wanna do is you want to identify which each of these are. So combustion reactions are simply when a substance reacts with oxygen. So you have a substance that's usually a hydrocarbon. So for this insensible, say, a hydrocarbon reacts with oxygen gas To produce co two and water. And this will always be known as a combustion reaction. A precipitation reaction, precipitation reaction is when we're in Aquarius solutions. So a quick solutions react and they form a precipitate or a solid. They form a precipitate or a solid and last but not least a dis proportion. Ation reaction. Shia Nation reaction is essentially a redox reaction. So it's a redox reaction where only one element undergoes oxidation and reduction. So a single element that undergoes oxidation and reduction. And so let's figure out which of these products which answers these fall under. So for our first chemical reaction here, we have peroxide dissolving into water and oxygen. We see here, this is going to be known as our this propia Nation reaction. And why is that? Well, in this case we're going to be paying attention to oxygen. So the oxidation number for oxygen For our peroxide is negative one On the right here for water, it's going to be -2. And oxygen gas by itself is always going to have an oxidation number of zero. So you can see here that the oxidation here an oxidation number here is both decreasing and increasing its going from negative one to negative two, which is a decrease and it's going from negative 1-0 which is an increase. So this element oxygen is undergoing disproportionate nation. And so the first one is going to be dis appropriate nation. The second one here we see that we have methane plus oxygen gas gives us C. +02 and H +20. And this is going to be our combustion reaction. As we stated before. A combustion reaction is one where we have a hydrocarbon reacting with oxygen gas to give us c. and water. And that is exactly what this reaction is. And last but not least, we have our precipitation reaction. What we said before a precipitation reaction is one where we have a solid product that is formed from Aquarius. So we have our two acquis reactant and we have this solid product here that has been formed and so three is going to be known as our precipitation reaction. And the only answer choice that correctly identifies each of these is going to be answer choice C. And with that we've answered the question overall. I hope this helped until next time
