Answer: -
If 13.3 mole of Co(NO₃)₂ are reacted, 26.6 mole of NaNO₃ are produced.
Explanation: -
The balanced chemical equation for the production of NaNO₃ from Co(NO₃)₂ is
Co(NO₃)₂ + Na₂SO₄ → 2 NaNO₃ + CoSO₄
From the balanced equation we see that
1 mole of Co(NO₃)₂ gives 2 moles of NaNO₃
13.3 mole of Co(NO₃)₂ gives moles of NaNO₃
= 26.6 mole of NaNO₃
Answer:
Oceanic trenches
Explanation:
Oceanic Trenches are hemispheric-scale long but narrow topographic depressions of the sea floor
Instead, it is extracted by electrolysis. The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite - another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own. The usual aluminium ore is bauxite.
Answer:
2.3 g NaCl
Explanation:
Given the concentration of the NaCl solution = 0.92% (w/v)
It means that 0.92 g of NaCl is present in 100 mL of water.
Thus,
100 mL of water contains 0.92 g of NaCl
To find, amount of NaCl in 250 mL of water
So,
1 mL of water contains of NaCl
250 mL of water contains of NaCl
<u>2.3 g of NaCl is present in 250 mL of this solution.</u>
