Answer:
The Deeper these nodules are, the harder it becomes. To use robotic submersibles eliminates the need for oxygen for people, but they would need an especially designed loader or mechanical “hands” to gather, and Balloons could Raise the mined Mn to the surface for collection.
Explanation:
Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Moles of 
The balanced reaction for dissociation will be:
Thus for 4 moles of 
, there is 1 mole of 
Thus moles of 
Molarity of 
Thus the molarity of the solution = 0.06 M
b) Mass of = 
Thus mass of Wenzhou use is 3.13 grams.
Answer:
Alkali metal hydroxides can be used to test the identity of metals in certain salts. The colour of the precipitate will help identify the metal : Calcium hydroxide is soluble; no precipitate is formed.
Answer:
= 2.33 L
Explanation:
V1/T1 = V2/T2
V1 = 3.0 L
T1 = 78 + 273
= 351 K
At s.t.p the temperature is 273 K and pressure is 1 atm.
V2 = ?
T2 = 273 K
V2 = V1T2/T1
= (3.0 ×273)/351
= 2.33 L
