The dissociation equation is:
AgNO3 = Ag+ + NO3-
We write the Ksp expression.
Ksp = [Ag+] [NO3-]
Since there is 1:1 molar ratio, we can assign the two values at the right side with s which represents the molar solubility.
<span>1.8E^-10 = (s)(s)
</span><span>1.8E^-10 = s^2
</span>s=1.34 x 10^-5 M
The net ionic equation for the precipitation of calcium phosphate from aqueous solution is Ca²+ (aq)+ S²- (aq)=>CaS(s)-----> CaS(s).
<h3>How is a precipitation process expressed in a net ionic equation?</h3>
For a precipitation reaction, the net ionic equation is written by first knowing the precipitate, then use the solubility rules (if there are any).
Then one can write down the precipitate's formula that was made to the right of an arrow. The ions that react to get the precipitate as the reactants to the left of the arrow should have their formulas written down also:
Hence:
Since the molecular fomular is: H2S(aq) + CaCl2(aq) -------> CaS(s) + 2HCl(aq)
Then the full ionic equation will be: 2H^+(aq) + S²-(aq) + Ca²+(aq) + 2Cl^-(aq) -------> CaS(s) + 2H^+(aq) + 2Cl^-(aq)

Thus we can balance the oxygen atoms by putting a prefix of 25/2 on the left side. To obtain a equation containing whole numbers, we multiply the entire equation by 2. This gives the final equation. 2 C8H18 + 25 O2 ---> 16 CO2 +18 H2O.
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
