The molecular formula for methanol is CH3OH. Which model shows methanol? (black = carbon; red = oxygen; white = hydrogen)
2 answers:
<h3><u>Answer; </u></h3>
B
<h3><u>Explanation;</u></h3>- <u><em>Methanol is the first member of alkanols or what we call alcohols. Alcohols are hydrocarbons whose functional group is hydroxyl group (OH)</em></u>
- Methanol has <em><u>a single carbon, one oxygen atom and four hydrogen atoms, three are attached to carbon atom and the other one is attached to oxygen atom.</u></em>
The most appropriate model showing methanol is B, attached below.

1)we need a balanced equation: CuSO₄ + Zn ---> ZnSO₄ + Cu
2) we need to convert the grams of CuSO₄ to moles using the molar mass.
molar mass CuSO₄= 63.5 + 32.0 + (4 x 16.0)= 160 g/mol
3) convert moles of CuSO₄ to moles of Cu
4) convert moles of Cu to grams using it's molar mass.
molar mass Cu= 63.5 g/mol
I did it step-by-step as the explanation but you can do all of this in one step.
