Answer:
Oxidation half
Ca -----> Ca2+ +2elecyrons
Reduction half
Cl2 + 2electrons ------> 2Cl-
Explanation:
Answer:
1.Precipitation
2.Transpiration
3.Condensation
4.Evaporation
5.Evaporation
3.Condensation
Explanation:
Rain pours from the sky occurs due to the process of precipitation, leaves of the plant dried due to the process of transpiration in which the water is evaporated from the body of plant, fluffy clouds form in the sky occurs in the process of condensation, bathing suit dries after swim is due to evaporation in which water is removed and goes into the atmosphere and water puddles disappear due to the process of evaporation. Evaporation is the removal of water from the any surface whereas transpiration is the removal of water from plant body parts.
The model represents Photosynthesis. Light, carbon dioxide, and water are the reactants. The products will be Sugar and Oxygen. Photosynthesis releases oxygen and glucose. Which is the energy that living things need to survive.
Answer:
pH = 9.475
Explanation:
Hello there!
In this case, according to the basic ionization of the hydroxylamine:

The resulting equilibrium expression would be:
![Kb=\frac{[HONH_3^+][OH^-]}{[HONH_2]} =1.1x10^{-8}](https://tex.z-dn.net/?f=Kb%3D%5Cfrac%7B%5BHONH_3%5E%2B%5D%5BOH%5E-%5D%7D%7B%5BHONH_2%5D%7D%20%3D1.1x10%5E%7B-8%7D)
Thus, we first need to compute the initial concentration of this base by considering its molar mass (33.03 g/mol):
![[HONH_2]_0=\frac{1.34g/(33.03g/mol)}{0.500L} =0.0811M](https://tex.z-dn.net/?f=%5BHONH_2%5D_0%3D%5Cfrac%7B1.34g%2F%2833.03g%2Fmol%29%7D%7B0.500L%7D%20%3D0.0811M)
Now, we introduce
as the reaction extent which provides the concentration of the hydroxyl ions to subsequently compute the pOH:

However, since Kb<<<<1, it is possible to solve for
by easily neglecting it on the bottom to obtain:
![x=[OH^-]=\sqrt{1.1x10^{-8}*0.0811}= 2.99x10^{-5}](https://tex.z-dn.net/?f=x%3D%5BOH%5E-%5D%3D%5Csqrt%7B1.1x10%5E%7B-8%7D%2A0.0811%7D%3D%202.99x10%5E%7B-5%7D)
Thus, the pOH is:

And the pH:
