The complete balanced chemical equation for this is:
<span>3KOH + H3PO4
--> K3PO4 + 3H2O</span>
First we calculate the number of moles of H3PO4:
moles H3PO4 = 0.650 moles / L * 0.024 L = 0.0156 mol
From stoichiometry, 3 moles of KOH is required for every
mole of H3PO4, therefore:
moles KOH = 0.0156 mol H3PO4 * (3 moles KOH / 1 mole
H3PO4) = 0.0468 mol
Calculating for volume given molarity of 0.350 M KOH:
Volume = 0.0468 mol / (0.350 mol / L) = 0.1337 L = 133.7
mL
Answer:
<span>133.7 mL KOH</span>
Answer:
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.

Answer:4.15 is already in the hundreths place so you are good!
if it was 4.155 then you would round it to 4.16 but its NOT that so the answer IS 4.15
Explanation:
The answer is C ( The evaporation rate of water increases at all temperatures causing an increase in volume.)
Answer:
The correct answer is option c. transfer of electrons from Mg to O.
Explanation:
Hello!
Let's solve this!
When Magnesium (Mg) reacts with oxygen (O), magnesium oxide is formed.
This reaction is spontaneous and occurs with oxidation number +2 of magnesium and oxidation number -2 of oxygen. It is an ionic union, so magnesium transfers its electrons to oxygen.
We conclude that the correct answer is option c. transfer of electrons from Mg to O.
