The centers for disease control and prevention (CDC) develops recommendations for water fluoridation along with technical requirements for each major compound used.
<h3>What is meant by water fluoridation?</h3>
Almost all water contains some fluoride, but usually not enough to prevent tooth decay. Fluoride can also be added to drinking water supplies as a public health measure for reducing cavities. Water fluoridation is the process of adding fluoride to the water supply so the level reaches approximately 0.7 ppm or 0.7 milligrams of fluoride per liter of water, this is the optimal level for preventing tooth decay.

B. The rate of diffusion increases with the increase in number of particles and temperature. Temperature increases particle speed, and more particles means there are more to move with the temperature.
This will require 266.9k j of heat energy my explanation for this is to calculate the energy required to raise the temperature of any given substance here what you require the mass of the material,m the temperature change that occurs AT
Answer:
Explanation:
Hello.
In this case, given the heat of fusion of THF to be 8.5 kJ/mol and freezing at -108.5 °C, for the required mass of 5.9 g, we can compute the entropy as:
Whereas n accounts for the moles which are computed below:
Thus, the entropy turns out:
