4. Pick a "for every" statement about silver nitrate and silver in this reaction. __ For every 1 mole of silver nitrate, the reaction uses 1 mole of silver. __ For every 1 mole of silver nitrate, the reaction makes 1 mole of silver. __ For every 2 moles of silver nitrate, the reaction makes 2 moles of silver. __

## Step 1<br />The problem is asking us to identify the correct "for every" statement about silver nitrate and silver in a reaction. The "for every" statement is a way of expressing the stoichiometry of a chemical reaction, which is the ratio of reactants to products.<br /><br />## Step 2<br />The first statement, "For every 1 mole of silver nitrate, the reaction uses 1 mole of silver," is not correct. This is because the stoichiometry of the reaction is not 1:1. Silver nitrate (AgNO3) is a compound that contains silver, but it also contains other elements such as nitrogen and oxygen. Therefore, it is not correct to say that 1 mole of silver nitrate would use 1 mole of silver.<br /><br />## Step 3<br />The second statement, "For every 1 mole of silver nitrate, the reaction makes 1 mole of silver," is also not correct. This is because the stoichiometry of the reaction is not 1:1. Silver nitrate (AgNO3) is a compound that contains silver, but it also contains other elements such as nitrogen and oxygen. Therefore, it is not correct to say that 1 mole of silver nitrate would make 1 mole of silver.<br /><br />## Step 4<br />The third statement, "For every 2 moles of silver nitrate, makes 2 moles of silver," is correct. This is because the stoichiometry of the reaction is 1:1. This means that for every 1 mole of silver nitrate, the reaction makes 1 mole of silver. Therefore, if we have 2 moles of silver nitrate, the reaction would make 2 moles of silver.
