Answer:
Question 2: Na3PO4, KOH; Question 3: Na3PO4, KOH
Explanation:
Question 2
The reactants in a chemical equation are the species on the left side of the reaction arrow.
Thus the reactants are Na3PO4, KOH (sodium phosphate and potassium hydroxide).
Question 3.
The products in a chemical equation are the species on the right side of the reaction arrow.
Thus the products are NaOH, K3PO4 (sodium hydroxide and potassium phosphate).
Conductivity, malleability, and high melting points. Hope this helps :)
The answer here would be 14.9 %KCl and here is how I can explain why:
33.5g / 225.6g x 100% = 14.9%
<span>you are looking for % of KCl in the solution, you have to add the mass of the KCl and water to get the total mass of the solution
Hope this helps a lot

Answer:
Explanation:
<u>1) Data:</u>
a) M = 0.5 M
<u>Note</u>: since the question is about volume (liters) and moles of solute, the correct unit for the concentration of the hydroxide solution is M (upper case) which is the unit for molarity. Lower case m is used for molality, and you cannot calculate the volume of the solution unless you know some other data, e.g. density of the solution.
b) n = 2
c) V (in liters) = ?
<u>2) Formula:</u>
Molarity is the number of moles of solute per liter of solution:
<u>3) Solution:</u>
a) Clear V from the formula: V (in liters) = M / n
b) Substitute: V (in liters) = 2 moles / 0.5M = 4 liters ← answer
