Answer:
The correct answer is 150 kilograms.
Explanation:
Based on the given information, the ratio of zinc and copper within the alloy is 2:5. The amount of zinc used in the alloy is 60 kg. Now the amount of copper used within the alloy would be,
Zinc/Copper = 2/5
60/Copper = 2/5
Copper(Cu) = 60*5/2
Cu = 150 Kilograms.
Thus, the amount of Cu used in the alloy is 150 Kg.
Answer:
46. 2 moles of NaOH
Explanation:
Balanced chemical equation between sodium hydroxide and sulfuric acid
2NaOH + H2SO4 = Na2SO4 + 2H2O
I mole of sulphuric acid is neutralized by = 2 moles of NaOH
23.1 mole of sulphuric acid is neutralized by = 2 x 23.1
= 46. 2 moles of NaOH
MgCl2 would be magnesium chloride.
