The answer is GENETIC DIVERSITY and SPECIES DIVERSITY
Answer: pH of the given solution is 8.7.
Explanation:
For the buffer mixture, initial pOH will be given as follows.
pOH =
=
=
= 5.523
When 0.05 mol NaOH is added to this buffer solution then concentration of species present will be as follows.
0.05 mol 0.25 0.75 0
0 0.20 (0.75 + 0.25) 0.05
Hence, the volume of solution will be 1 liter.
[BOH] = , [Salt] =
So, pOH = [/tex]
= 6 - 0.69
= 5.30
Now, we will calculate the pH as follows.
pH = 14 - 5.30
= 8.7
Thus, we can conclude that pH of the given solution is 8.7.
Answer:
The heat of reaction -1.9 kilo Joules.
Explanation:
Volume of the hydrogen peroxide solution = 50.0 mL
Volume of the ferric nitrate solution = 10.0 mL
Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL
Heat capacity of the mixture = c = 4.18 J/g°C
Change in temperature of the mixture = ΔT = 7.47°C
Heat absorbed by the mixture = Q
Heat release due to reaction = -Q'
-Q' =Q (law of conservation of enrage)
Q'= -Q = -1.9 kJ
The heat of reaction -1.9 kilo Joules.
Answer:
Elements are in the same amounts but they are different compound. So it is False:)
