I believe only one atom of oxygen is in a molecule of acetaldehyde.
Answer:
1-butene
Explanation:
To name the compound, start counting from the side that gives the double bond the lowest low count since the functional group of the compound is the double.
Now in the name of the compound, we must indicate the position of the double bond.
The name of the compound is butene. But the position of the double is unknown. Since we started counting from the left, the double bond is at carbon 1.
Therefore, the name of the compound is 1-butene

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
