The K w for water at 0 ∘ C is 0.12 × 10 − 14 M 2 . Calculate the pH of a neutral aqueous solution at 0 ∘ C . p H = Is a pH = 7.2
Karo-lina-s [1.5K]

Answer:

pH → 7.46

Explanation:

We begin with the autoionization of water. This equilibrium reaction is:

2H₂O  ⇄   H₃O⁺  +  OH⁻            Kw = 1×10⁻¹⁴         at 25°C

Kw = [H₃O⁺] . [OH⁻]

We do not consider [H₂O] in the expression for the constant.

[H₃O⁺] = [OH⁻] = √1×10⁻¹⁴   →  1×10⁻⁷ M

Kw depends on the temperature

0.12×10⁻¹⁴ = [H₃O⁺] . [OH⁻]  → [H₃O⁺] = [OH⁻]         at 0°C

√0.12×10⁻¹⁴ = [H₃O⁺] → 3.46×10⁻⁸ M

- log [H₃O⁺] = pH

pH = - log 3.46×10⁻⁸ → 7.46

Changes to the global climate could include _______.
frosja888 [35]

1. Answer is d. all of the above.

Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.

2. Answer is c. ozone.

Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.

Heat Flow Inside Earth Activity
Slav-nsk [51]

Tectonic plates are pieces of Earth’s crust, and mantle referred to as the lithosphere. They mainly consist of two types of material: oceanic and continental crust. Some of the most famous theories of the movement of tectonic plates involved gods of Greek mythology. For instance, many people believed the popular Greek king of the ocean, Poseidon, was responsible for Tsunamis, vicious waves, and even the expansion of the ocean. He was responsible for the movements of the ocean at the time. But nowadays, we notice, based on scientific and environmental facts, that the tectonic plates might have been shifting due to the intense heat in the Earth’s core, causing the mantle’s lithosphere to move.
