A for the first and b for the second!!:))
An example of a land form from magma is B. Lava Plateau.
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.

usually made from sand
Answer:
Partial pressure of oxygen
atm
Partial pressure of Helium
atm
Explanation:
We will first find the number of moles of each gas
The molar mass of oxygen is
grams per mole
The molar mass of helium is
grams per mole
The number of moles of oxygen in the solution

The number of moles of helium in the solution
The number of moles of oxygen in the solution

Total number of moles in the solution is equal to
Partial pressure of oxygen
atm
atm
Partial pressure of Helium
atm
