False. elements in the same period have the same number of shells while elements in the same group have the same number of valence electrons.
Answer:
0.500 moles of oxygen
Explanation:
<em>Full question says: "Calculate the moles of oxygen needed to produce 0.500 moles of acetic acid.</em>
<em />
The reaction of ethanol (C₂H₅OH) with oxygen (O₂) is:
C₂H₅OH + O₂ → CH₃COOH + H₂O
<em>Where 1 mole of ethanol reacts per mole of oxygen to produce 1 mole of acetic acid (CH₃COOH) and 1 mole of water</em>
<em />
Based on the chemical equation (1 mole of oxygen produce 1 mole of acetic acid; Ratio 1:1). Thus, if you want to produce 0.500 moles of acetic acid you will need:
<h3>0.500 moles of oxygen</h3>
