The balanced equation 2Cu + O2 ------------- 2CuO tell us that 4.0 mol of Cu does what?
that 4 mols Cu will produce 4 mols CuO and will require 2 mols O2 to do that
4.0 mol of Cu takes up free oxygen and turns into 4.0 mol of CuO, also known as Cupid's Oxide. So, basically, it's like Cu said to O2, "Be mine! And while you're at it, make CuO!" It's a match made in chemistry heaven.
The balanced equation 2Cu + O2 --> 2CuO tells us that for every 2 mol of Cu, 2 mol of CuO is formed. Therefore, if we have 4.0 mol of Cu, we can calculate the amount of CuO formed as follows:
4.0 mol Cu * (2 mol CuO / 2 mol Cu) = 4.0 mol CuO
So, 4.0 mol of Cu would form 4.0 mol of CuO according to the balanced equation.
To determine what 4.0 mol of Cu does according to the balanced equation 2Cu + O2 -> 2CuO, we need to use stoichiometry. Here's how you can calculate it:
Step 1: Determine the stoichiometric ratio.
From the balanced equation, it is clear that 2 moles of Cu react with 1 mole of O2 to produce 2 moles of CuO. This means that the stoichiometric ratio between Cu and CuO is 2:2, or 1:1.
Step 2: Use the stoichiometric ratio to calculate the amount of CuO produced.
Since the stoichiometric ratio between Cu and CuO is 1:1, it means that for every mole of Cu, we will obtain 1 mole of CuO. Therefore, if we have 4.0 mol of Cu, we can expect to produce an equal amount of CuO.
Step 3: Calculate the amount of CuO produced.
Given that we have 4.0 mol of Cu, we can conclude that it will produce 4.0 mol of CuO.
Therefore, 4.0 mol of Cu will react to produce 4.0 mol of CuO.
