Saliva's buffering capacity and flow of secretion are directly related to the rate and extent of demineralization. ... Saliva can act as a replenishing source and inhibit tooth demineralization during periods of low pH, while promoting tooth remineralization when the pH returns to a neutral state.
Answer:
Precentage error = 7.23%
Explanation:
The precentage error formula is the useful method for determining precision of your experimental result
It can be calculated using :
So we get percentage error = 7.23%
Precision means how close the experimental value to the true value or theoretical value
If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment
If the percentage error is zero it means the experiment is perfectly done without inaccuracy
<span>Those characteristic belong to an ionic compountd. Ionic compounds have strong bonds between their atoms (ionic bond is the strongest molecular bond) which conferes this kind of compounds high melting point, wich 9811 K is. Ionic compounds do not transmit current, because they do not have free electrons, like metals do, then they are poor conductors as solid. Ionic compounds dissolve in water into ions which are charges that can move, becoming then good conductors. The structure of ionic compound is a net of cristals which make them hard and brittle. Then, the answer i s option (4) an ionic compound.</span>
I would say 6.022<span>⋅1023 atom</span>
