Blue to red is acidic, red to blue is basic and no change is neutral.
The answer it the function
Use the following equations to fill the chart.
E = hf
where
h = 6.63 x 10⁻³⁴ J/s, Planck's constant
f = frequency Hz
E = quanta of energy, J
c = fλ
where
c = 3 x 10⁸ m/s, the velocity of light
λ = wavelength, m
If energy is given in J/mmol, divide by Avogadro's number, N = 6.02 x 10²³, to convert it to J.
The completed table is shown below.
Summer days are warmer because the path of the sun is longer and we have more direct sunlight during that time
Let the solution cool down really slowly, don’t disturb it at all.
