Answer:
All statements are true
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion,
.
Hence, statement 1 is correct.
Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-
Hence, statement 2 is correct.
Acetic acid will dissociate as:-
![CH_3COOH\rightleftharpoons CH_3COO^-+H^+](https://tex.z-dn.net/?f=CH_3COOH%5Crightleftharpoons%20CH_3COO%5E-%2BH%5E%2B)
Hence, statement 3 is also correct.
The answer you're looking for is B. The bond will be ionic.
<span>the table say that at 20 degree celcius 88.0g of NANO3 will remain dissolved in
100 gm of H2O
so at 20 degree celcius 80.0g of H20 will dissolve
(88.0g)x(80g/100g)=70.4g of NANO3
so at 20 degree celcius
86.3g-70.4g= 15.9 gram of NANO3 will come out of solution.</span>
Answer:
OMG so big question!!!!!!!!!!!!
- If the abundance of the first isotope is 68.037%, then the abundance of the second isotope is 100%-68.037%.
Substituting into the atomic mass formula,
![47.574=(46.449)(0.68037)+x(1-0.68037)\\\\ 47.574=31.60250613+0.31963x\\\\15.97149387=0.31963x\\\\x \approx \boxed{49.969 \text{ u}}](https://tex.z-dn.net/?f=47.574%3D%2846.449%29%280.68037%29%2Bx%281-0.68037%29%5C%5C%5C%5C%2047.574%3D31.60250613%2B0.31963x%5C%5C%5C%5C15.97149387%3D0.31963x%5C%5C%5C%5Cx%20%5Capprox%20%5Cboxed%7B49.969%20%5Ctext%7B%20u%7D%7D)
