How does pH work?A measurement of a solution's acidity or alkalinity that is equal to the common logarithm of the reciprocal of the amount of hydrogen ions present in the solution in moles per cubic decimeter. A pH of 7 refers to pure water, a pH of less than 7 to acid solutions, and a pH of more than 7 to alkaline solutions.
What pH range is ideal?A good balance of acidity and alkalinity is something that the human body is designed to do on its own. The kidneys and lungs play a significant role in this process. On a scale of 0 to 14, where 0 is the most acidic and 14 is the most alkaline.
Breif:
Kb = 3.5X 10^ —6
Concentration, C= 0.24M
Since it's basic solution, there will be OH ^-
But,[ OH-] = √KbC
= √(3.5×10−6 X 0.24 ) = 9.1652 X10^ —4
[OH- ] = 9.1652 X10^ —4
POH = -log[OH- ]

water changes. Does it go up or down? Why? How would this affect
cooking on a mountain? Explain why the boiling point changes at
higher altitude and design a solution to this cooking problem.
The air pressure at high altitudes is quite low when compared to that at sea level. Compared to cooking at sea level, cooking at high altitudes is different.
Water at high altitudes boils at a lower temperature as a result. Lower air pressure results in a faster rise of water to the boiling point.
At a greater altitude, there is less energy and consequently less heat, hence water will boil at a lower temperature.
Any liquid's boiling point is determined by the amount of air pressure pressing against its surface. The higher the pressure, the more energy is needed for liquid molecules to flee the top and form a gas, and as a result, the higher the temperature at which the liquid boils.
What is boiling point?
Boiling point is the temperature at which a liquid's internal pressure equals the external pressure exerted by the liquid's vapour; in this situation, the addition of heat causes the liquid to turn into its vapour without rising the temperature.

In chemistry, molecular orbital theory is a method for using quantum mechanics to describe the electronic structure of molecules. It was proposed in the early twentieth century. The atomic orbitals combine to form the molecular orbital. The electrons of molecules fill the new energy states of the molecular orbitals in the same way that the energy states of the atomic orbitals are filled.
The number of molecular orbitals produced is always equal to the number of atomic orbitals brought by the combining atoms. Bonding molecular orbitals have less energy than parent orbitals, while antibonding orbitals have more energy.

(18.015g / mol) x 2.768 moles H₂O =
the theoretical yield is 49.86g H₂O
Yield percentage:
Actual yield divided by theoretical yield multiplied by 100 equals the percent yield.
32.8g H₂O / 49.86g ₓ 100 =65.7%
The percentage yield of the reaction is 65.7%
