Answer:
Explanation:
C₆H₅NH₂ + H₂O = C₆H₅NH₃⁺ + OH⁻
C₆H₅NH₃⁺ is also called anilinium ion . Thus we see that aniline reacts with water to form anilinium ion and forms OH⁻ ion . Due to it, it shows basic properties . The pH value of this aqueous solution is more than 7 . But it is a weak base because the concentration of OH⁻ formed is very less . It is so due to its less value of Kb . It has been explained as follows
Kb =
Since Kb is 4.3 x 10⁻¹⁰ which is very low value so concentration of OH⁻ that is [OH⁻] formed will also be very low . Hence it will be a weak base.
Answer:
Salinity, along with temperature, determines the density of seawater, and hence its vertical flow patterns in thermohaline circulation. 2. Salinity records the physical processes affecting a water mass when it was last at the surface. Hope this helps!
Explanation:
I think its the mass that changes but im not sure
Answer:
3,46 atm
Explanation:
Tenemos;
P1 =?
T1 = 100 + 273 = 373 K
V1 = 40 litros
P2 = 6 atmósferas
T2 = 50 + 273 = 323 K
V2 = 20 litros
Desde;
P1V1 / T1 = P2V2 / T2
P1V1T2 = P2V2T1
P1 = P2V2T1 / V1T2
P1 = 6 * 20 * 373/40 * 323
P1 = 44760/12920
P1 = 3,46 atm
Answer:
a) 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
Explanation:
The energy required to break the bond= energy of the incident photon
E= 941 × 10^3/6.02 × 10^23 = 1.56 ×10^ -18 J
From
E= hc/λ
h= Plank's constant
c= speed of light
λ= wavelength of incident photon
λ= hc/E
λ= 6.6 ×10^-34 × 3 ×10^8/1.56 ×10^ -18 J
λ= 1.269 × 10^-7 m
b) This wavelength occurs in the ultraviolet region of the electromagnetic spectrum
