Answer:
0.01185M = moles/0.02755L
0.02755*0.01185=0.00032647
Explanation:
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)

So basically Positive reinforcement is when you give someone something for showing a good behavior, and a negative reinforcement is giving someone a consequence for showing bad behavior.
Hope this helps:)
Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.
According to Bohr's theory, it is difficult to locate electron or cannot be located in a definite region. Electron has to be found in an orbit and nowhere else. When the probability of finding an electron in a given spherical shell around the nucleus is plotted the distance of the electron from the nucleus for the hydrogen atom, the graph indicates that the probability of finding the electron increases as the distance between the electron and the nucleus decreases
Bohr claimed that electrons a entities had only probabilities if they weren't observed. While Einstein argued that they had independent reality.
But in wave mechanics Model, there is a slight chance of knowing the location of the electron.
Heisenberg uncertainty principle also claim the possibility of knowing the position of electron. Albert Einstein also claim that; to determine the position of an electron to an accurate extent, you would have to compromise your ability to know it's momentum. This inaccuracy will eventually affect the measurement of momentum which will be extremely uncertain.
