Answer:
The answer in °C is 3498.85°C
Explanation:
The Celsius scale is considered a derived scale, defined in relation to the Kelvin scale.
The zero on the Celsius scale is defined as 273.15 K. This means that 100°C is defined as the equivalent of 373.15 K.
The Celsius scale is of intervals but not of proportions, which means that it pursues a relative scale and not an absolute scale.
To calculate the temperature in °C at which the tin becomes superconducting we will use the following formula:
°C = Temperature in K - 273.15 = 3772 - 273.15 = 3498.85°C
Sulfur dioxide diffuses at one quarter the rate of helium :)

Answer:
3.97
Explanation:
pH of buffer solution = pKa+Log(Cb/Ca)
pH of buffer solution = -log(Ka)+log(Cb/Ca)............... Equation 1
Where Ca = concentration of acid, Cb = concentration of base.
Given: Ka = 6.5×10⁻⁵, Ca = 0.25 M, Cb = 0.15 M
Substitute into equation 1
pH of buffer solution = -log(6.5×10⁻⁵)+log(0.15/0.25)
pH of buffer solution = 4.19+(0.22)
pH of buffer solution = 3.97.
