Best ResponseYou've already chosen the best response.01. In 1912, chemist Fritz Haber developed a process that combined nitrogen from the air with hydrogen at high temperatures and pressures to make ammonia. Specifically, the process involved combining one molecule of nitrogen gas (N2) with three molecules of hydrogen gas (H2) to get two molecules of ammonia (NH3). If you write this process in a symbol format, it looks like this: N2 + 3H2 → 2NH3 Explain whether this is a chemical or physical change, and why. Does it involve elements, compounds, mixtures, or pure substances? Also describe how many atoms are involved before and after. What do you notice about the number of atoms? Answer:

Best ResponseYou've already chosen the best response.0OK What do you think is a chemical (change in the nature of the substance) or a physical (the substance still the same before and after the reaction?

Best ResponseYou've already chosen the best response.1What you probably aren't familiar with is that Fritz Haber, probably one of the most famous/infamous chemists of all time also developed mustard gas, which was widely used in WWI by the german army, as a chemical weapon.

Best ResponseYou've already chosen the best response.1this is unrelated though but I find it fascinating. Think about what's happening in the reaction, are new compounds being formed and what's happening @PrincestonA

Best ResponseYou've already chosen the best response.0the proportion of N and H in the NH3 are always constant it is a compound (like H2O is not a mixture of H and O)

anonymous

Best ResponseYou've already chosen the best response.0do you have any mixtures, or pure substances in the reaction?

anonymous

Best ResponseYou've already chosen the best response.0So its a physical change because its not changing what the substance is

anonymous

Best ResponseYou've already chosen the best response.0it is a chemical reaction!!!! the N2 and H2 are elements and the NH3 is a compound. All of them are pure substances.

Best ResponseYou've already chosen the best response.0how many atoms are involved before and after?

anonymous

Best ResponseYou've already chosen the best response.0Ok can you remind me which one is the atoms and molecules, is it the one before the element or after

anonymous

Best ResponseYou've already chosen the best response.0in the case of the N2 you have two atoms, in the case of the H2 you have two atoms too, but you need 3H2 then you have a total 6 atoms in the 3H2 you multiply the number in front of the symbol by the number under the symbol 8 and 8 are the same number of atoms before and after the reaction N2 + 3H2 → 2NH3 2 atoms of N and 6 atoms of H

anonymous

Best ResponseYou've already chosen the best response.0About describing how many atoms are involved before and after, I know Cuanchi answered but I still don't quite get it

Photon336

Best ResponseYou've already chosen the best response.1well, do you know that in every chemical reaction: if we start out with a certain number of atoms, we must end off with that same number does this make sense? @PrincestonA

Photon336

Best ResponseYou've already chosen the best response.1let's say I have this reaction @princestonA i need you to follow along each step of the way, so i need you to participate. \[2A + 6B > 2AB_{3}\] < we will work with that reaction In every chemical reaction, the number of atoms of reactants must equal the number of atoms of products. Does this make sense

Best ResponseYou've already chosen the best response.1\[2A + 6B > 2AB_{3} \] Let's look at the reactants please tell me how many atoms of A and B we have in the reactants?

Photon336

Best ResponseYou've already chosen the best response.1Yes we have two reactants A and B. see those numbers in front of them? well because there is a 2 in front of A, we have 2 molecules of A how many molecules of B do we have in the reactants?

Best ResponseYou've already chosen the best response.1Now If we have 2 molecules of A, and 6 molecules of B in the reactants

Photon336

How many atoms for B on the reactant side 3. How many atoms for A on the product side 4. How many atoms for B on the product side

Best ResponseYou've already chosen the best response.0Explain whether this is a chemical or physical change, and why. Does it involve elements, compounds, mixtures, or pure substances? Also describe how many atoms are involved before and after. What do you notice about the number of atoms?

Best ResponseYou've already chosen the best response.1STEP 1. Count number of atom(s) on the reactant side for each element in the compound STEP 2. Count number of atom(s) on the product side for each element in the compound. the number of atoms should be the same on both sides.

Best ResponseYou've already chosen the best response.0Its a chemical Change because its change in the nature of the substance. N2 and H2 are elements and the NH3 is a compound. All of them are pure substances. And there are 8 atoms before the reation and 8 after the reaction.

Best ResponseYou've already chosen the best response.1they are the same on both sides. you have 2 atoms of nitrogen and 6 atoms of hydrogen on both sides. you notice that on both sides you have 8 atoms on each side. @PrincestonA you answered your own question and you got it right.

Best ResponseYou've already chosen the best response.0THANK YOU SO MUCH BRO!!!! I know I was slow asf at first but all I needed to do was eat something. I was studying and doing chem homework for 5 hours and starved myself and i started to shake and couldn't think right

Photon336

Best ResponseYou've already chosen the best response.1yeah no problem @PrincestonA great job, you got it now. like for every reaction you'll always have the same number of atoms on both sides for each element. always remember that, and make sure that you check too because sometimes the reaction isn't balanced.
