Answer:
<h2>Oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.</h2>
<h3>Valence electrons are the electrons in the outermost shell, or energy level, of an atom. </h3>
<h3>Configuration of oxygen's valence electrons as 2s²2p⁴.</h3>

Answer:
Copper(II) sulphate – sodium hydroxide reaction
The reaction between copper(Il) sulphate and sodium hydroxide solutions is a good place to start. If you slowly add one to the other while stirring, you will get a precipitate of copper(II) hydroxide, Cu(OH)2.
Is the something missing from the question
Answer:
5,250g
Explanation:
Density = Mass / Volume
*Note: mass = x
1.50g/mL = x / 3500mL
multiply 3500mL on both sides
1.50g/mL * 3500mL = 3500mL(x) / 3500mL
cancel units
x = 5250g
