First you figure out how many grams of sulfur has been used.
2.080g - 1.659g = 0.421g of S used
Now change all of your grams to mols.
1.659g of Cu / 63.546g/mol = 0.02611mol of Cu
0.421g of S / 32.065g/mol = 0.01313 mol of S
From this you can see that S has less so we divide both numbers by the number of moles of S so we can get a ratio of S to Cu.
0.01313/0.01313 = 1 for S
0.02611/0.01313 = 2 for Cu
So the empirical formula would be Cu2S or copper sulfide.
The Constitutions was designed to be flexible so new laws can be added as needed and old laws can be reinterpreted
Nope, sure don't sesrch it on amazon or something. Maybe youll find one and be able to but it.
Answer:
Explanation:
When it comes to electron configuration and orbitals, it's important to first identify what exactly we are trying to identify. Below is a given example:
Looking at the periodic table, identify the alkali metal family on the periodic table, or group one elements:
Notice how each configuration has an exponent of 
, representative of a single electron in their s-orbital.
