Answer:
0.171 grams of oxygen combined with the metal.
Explanation:
Mass of magnesium oxide produced = 0.421 g
Mass of magnesium metal used = 0.250 g
Suppose reaction completely converts the magnesium into magnesium oxide.
Mass of oxygen combined with magnesium = m
0.421 g = 0.250 g + m
m = 0.421 g - 0.250 g = 0.171 g
0.171 grams of oxygen combined with the metal.
When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.
<h3>What is Balanced Chemical Equation ?</h3>The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now write the chemical equation
CH₃COOH + CH₃OH ⇄ CH₃COOCH₃ + H₂O
Here
CH₃COOH is Ethanoic acid (Acetic acid)
CH₃OH is Methanol (Methyl Alcohol)
CH₃COOCH₃ is Methyl ethanoate (Methyl Acetate)
H₂O is water
Thus from the above conclusion we can say that When ethanoic acid react with methanol in the presence of H⁺ or heat it gives methyl ethanoate and water.
