We are given with
4.35 g Phosphoric acid
5.25 g KOH
3.15 g K3PO4 produced
The reaction is
H3PO4 + 3KOH => K3PO4 + 3H2O
First, convert masses into moles.
Then, determine the limiting reactant.
Next, determine the maximum amount of K3PO4 that can be produced from the limiting reactant.
Lastly, calculate the percent yield by dividing the actual amount produced by the theoretical amount produced.
dissociation of proton from the acid depends upon the central atoms's electronegativity
More is the electronegativity of halogen ⇒ more is its pull on the oxygen ⇒ easier will the bond breakage of O-H ⇒ higher the acidity
In terms of E.N :
Cl > Br > I
so HClO₃ is highest acidity with the highest Ka value
Answer:
light bends and makes effects in the water
Explanation:
A metallic bond since both are pure metals but are not ionic
Answer:
magnesium
Explanation:
1s^2 2s^2 2p^6 3s^2 3p^2 = 14
magnesium is 14th in the periodic table
3p^2 because you have said that 3p subshell is filled with two electrons only.
