Like all equilibrium constants, the value of Kw depends on temperature. At body temperature (37°C), Kw = 2.4 * 10-14. What are t
Aleksandr [31]

Answer:

pH = 6.8124

Explanation:

We know pH decreases with increase in temperature.

At room temperature i.e. 25⁰c pH of pure water is equal to 7

We know

Kw = [H⁺][OH⁻]...............(1)

where Kw = water dissociation constant

At equilibrium [H⁺] = [OH⁻]

So at 37⁰c i.e body temperature Kw = 2.4 × 10⁻¹⁴

From equation (1)

[H⁺]² = 2.4 × 10⁻¹⁴

[H⁺] = √2.4 × 10⁻¹⁴

[H⁺] = 1.54 × 10⁻⁷

pH  = - log[H⁺]

      = - log{1.54 × 10⁻⁷}

      = 6.812

Explanation:

Given:

Speed of runner = 4 km/h

Time taken = 2 hour

Find:

Distance cover

Computation:

Distance = Speed x Time

Distance cover = Speed of runner x Time taken

Distance cover = 4 x 2

Distance cover = 8 km

TEA [102]

Answer:

D

Explanation:

Glucose is produced through a process powered by sunlight that consumes Carbon Dioxide and produces oxygen as a waste product.  In order for glucose to be produced, Carbon dioxide (a compound) must be, in essence, converted into a completely different chemical: dioxygen.
