Answer:
0.375 moles of CaCO₃ are required
Explanation:
Given data:
Number of moles of sulfamic acid = 0.75 mol
Number of moles of calcium carbonate required = ?
Solution:
Chemical equation:
2H₃NSO₃ + CaCO₃ → Ca(SO₃NH₂)₂ + CO₂ + H₂O
Now we will compare the moles of H₃NSO₃ and CaCO₃ .
H₃NSO₃ : CaCO₃
2 : 1
0.75 : 1/2×0.75 = 0.375 mol
Thus, 0.375 moles of CaCO₃ are required.
Answer:
An impurity is something that ruins the uncontaminated nature of something. If someone accuses you of impurity, they think you or your nature has been spoiled in some way by sin. When water is pure, the only thing in that water is water.
Answer:
Prokaryotic cell
Explanation:
If you search it up you will see that the prokaryotic cell looks exactly alike with the picture you have posted.
Chemical reaction
C2H2(g) + H2O(g) ⇄ CH2CHO(g)
a) Removing H2O(g) from the system
Remember that Le Chatelier principle states that when an equilibrium is disturbed the system will try to counteract to restate the equilibrim.
If you remove H2O(g) then the equilibrium will be displaced to the left, trying to produce more H2O(g), which means to reduce CH3CHO(g) and increasing the C2H2(g).
b) Adding CH3CHO(g)
To counteract the addition of CH3CHO(g) the system will try to regain equilibrium by producing more reactants: C2H2(g) and H2O(g)
c) Removing C2H2(g)
The system will again displace to the left, that is CH3CHO(g) will reduce and H2O(g) will increase.
d) Adding H2O(g)
The systmen will displace to the right reducing C2H2(g) and increasing CH3CHO(g).
