Co2 will dissolve in water if water is saturated with Co2 first then it will absorb some of CO2 it appear as less is absorb that was actually the case . this would make it appear as present of CACO3 is in original sample is lower than it will be too low
B. Unless you melt the solid the solid will hold its form
Answer is: hydrogen (cathode), iodine (anode).
The balanced
oxidation half reaction: 2I⁻(aq) →
I₂(s) + 2e⁻.<span>
Iodine is oxidized (lost electrons) from -1
to neutral charge (0).
The balanced reduction
half-reaction: 2H</span>₂O(l) + 2e⁻ → H₂(g) + 2OH⁻.<span>
<span>Hydrogen is reduced (gain electrons) from
+1 to neutral charge.</span></span>
"The boron-nitrogen interaction in the studied molecules shows some similarities with the N→B bond in the H3N-BH3 molecule, formally understood as covalent-dative. ... The results show that all the studied BN bonds are triple, since three two-center orbitals have been obtained."
"Formation of a dative bond or coordinate bond between ammonia and boron trifluoride. When the nitrogen donates a pair of electrons to share with the boron, the boron gains an octet. ... In addition, a pair of non-bonding electrons becomes bonding; they are delocalized over two atoms and become lower in energy."
