yeah, let her b0yfriend know what she told you and you are telling him that simply because you want to avoid problems between them.
Answer:
5.28 moles of NaOH.
Explanation:
Step 1:
Determination of the number of mole in
375.4 g of any Na2S04.
Molar mass of Na2SO4 = (2x23) + 32 + (16x4) = 142g
Mass of Na2SO4 = 375.4g
Number of mole of Na2SO4 =..?
Mole = Mass /Molar Mass
Number of mole of Na2SO4 = 375.4/142 = 2.64 moles
Step 2:
The balanced equation for the reaction.
H2SO4 + 2NaOH —> Na2SO4 + 2H2O
Step 3:
Determination of the number of mole of NaOH needed for the reaction.
From the balanced equation above,
2 moles of NaOH reacted to produce 1 mole of Na2SO4.
Therefore, Xmol of NaOH will react to produce 2.64 moles of Na2SO4 i.e
Xmol of NaOH = 2 x 2.64
Xmol of NaOH = 5.28 moles
Therefore, 5.28 moles of NaOH is needed for the reaction.
Answer:
Burn, able to rust, and sour.
Explanation:
<span>The correct answer is option a. Compounds that do not dissociate show little to no conductivity.
The compounds that cannot dissociate into ions are not able to conduct electricity. Example- Carbonic acid is a weak electrolyte and sulphuric acid is a strong electrolyte. Carbonic acid dissociates very little in the solution and sulphuric acid dissociates very well. </span>
