λν=c f is solved for c, speed of light. v represents frequency and λ represents wavelength.
Answer: The pH of the substance is 8.25. The solution is basic.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.
Putting in the values:
Thus as pH is more than 7, the solution is basic.
The pH of the substance is 8.25. The solution is basic.
Conduction is particle to particle. Convection is by molecular motion. Radiation is energy that is transmitted in the form of rays or waves. C seems like the best answer.
