Does this look correct? Thx!
Write the balanced equation for the reaction between solid copper and silver nitrate, that produces solid silver and copper(II) nitrate in solution. Include your experimentally determined mole ratios for the copper and silver atoms as coefficients.
answer: 1Cu 2Ag+ -----> 1Cu+2 2Ag
No, it isn't correct but mostly because you omitted plus signs.
Cu + 2Ag^+ ==> Cu^+2 + 2Ag
The 1 isn't needed; writing Cu and we understand there must be 1 there or we wouldn't have written Cu. Anything other number than 1 must be typed in.
To determine if the given balanced equation is correct, we need to check if the number of atoms on both sides of the equation is balanced. Let's break down the reaction and balance it step by step.
The reaction is between solid copper (Cu) and silver nitrate (AgNO3):
Cu + AgNO3 -> Ag + Cu(NO3)2
Now, let's count the number of atoms on each side of the equation:
On the left side:
Concentrating on copper (Cu), we have one atom of copper.
On the right side:
Concentrating on copper (Cu), we have one atom of copper as well.
So far, the number of copper atoms is balanced.
Concentrating on silver (Ag), we have:
On the left side:
There are no silver atoms present.
On the right side:
We have two silver atoms.
We can see that the number of silver atoms is not balanced. To balance it, we need to place a coefficient of 2 in front of the silver nitrate (AgNO3):
Cu + 2AgNO3 -> 2Ag + Cu(NO3)2
Now, let's reassess the number of atoms:
On the left side:
Concentrating on copper (Cu), we still have one atom of copper.
On the right side:
Concentrating on copper (Cu), we have one atom of copper as well.
The number of copper atoms remains balanced.
Concentrating on silver (Ag), we have:
On the left side:
We have two silver atoms.
On the right side:
We also have two silver atoms.
Now, the number of silver atoms is balanced.
From the balanced equation, we can see that the experimentally determined mole ratio of copper to silver is 1:2. Therefore, the balanced equation is:
Cu + 2AgNO3 -> 2Ag + Cu(NO3)2
So, the given answer (1Cu 2Ag+ -----> 1Cu+2 2Ag) is incorrect.
