First we need to find the number of moles that 43.9g of gallium metal is. We can do this by finding the molar weight of gallium and cross-multiplying to cancel out units:
So we are dealing with 0.63 moles of gallium metal.
We can take from the balanced equation that 4 moles of gallium metal will react completely with 3 moles of oxygen gas. We can take this ratio and make a proportion to find the amount of oxygen gas, in moles, that will react completely with 0.63 moles of gallium metal:
Cross multiply and solve for x:
So now we know that 0.47 moles of oxygen gas will react with 43.9g of gallium metal.
<u>Answer:</u> The correct answer is is the base and
is the salt.
<u>Explanation:</u>
Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce salt and water as products.
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and a base is defined as a substance which accepts protons.
For the given chemical reaction:
Here, is a base because it is accepting proton and HCl is an acid because it is loosing proton.
is considered as a salt because it is formed by the combination of acid and base.
Hence, the correct answer is is the base and
is the salt.
