yield?

im confused on thie how exactly can you tell wat a mixture will yield like what would c+ HNO3--> ? not this one in specific im just curios how you would find out my teacher always just tells us instead of making us figure it out on our own.

 

 

Your teacher is right.

 

Even better would be if he show reaction experimentally in lab.

 

What molecules do you know which are made of atoms that you mentioned above? Make a list of them.

 

Quantity of atoms must match on both sides of equation.

f.e.

 

H2O + Cl2 -> ...

 

On the left you have:

2 atoms of Hydrogen

1 atom of Oxygen

2 atoms of Chlorine

 

H2O + Cl2 -> HCl + HClO

 

Count atoms on the right side of equation, and you will see exactly the same quantity of atoms as on the left.

Depending on how far along you are in chemistry, the answer to that particular example might not be a very straight forward one for you. How much on redox chemistry have you covered so far? HNO3 is an oxidising agent, which means that it is probably going to oxidise (i.e. strip electrons away from) the carbon and cause the nitrogen to be reduced. You may have some inclination what types of procusts you'd get from that process if you've covered it.

 

Simply counting atoms as suggested by Sensei might not be very helpful in predicting reaction outcomes if you don't have some understanding of the processes that cause certain things to react in the way that they do or at least have a knowledge of what kind of products result from various types of combinations. Really what it's helpful in is balancing equations, but that of course assumes that you already know the products. There are a number of general rules you may have learned or will learn, but I'd be curious to know what topic you are currently going through in class before I link you information that may or may not be helpful to you.

 

Edit: I will link this PDF, though. It goes over the more basic questions you'll encounter, though it's obviously far from complete.
