Answer:the medication would not last as long
Explanation:
Because of the desolving of the tablet so quickly it would
Answer:
True
Explanation:
It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.
1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.
2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.
The values of pH and pOH always obey the following expression:
pH + pOH = 14
Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.
For example, in an acidic medium:
if pH= 3, pOH= 11
In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.
Answer:
Last week, it was announced that four new elements would be added to the periodic table, a collaboration from researchers in Russia, Japan and the U.S. Elements 113, 115, 117, and 118, which will complete the seventh row, are superheavy elements, that have an atomic number greater than 104.
Explanation:
Explanation:
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Higher energy level
= Lower energy level
1) The wavelength of the n=4 to n=1.
Putting the values in above equation, we get:
The region of this electromagnetic transition will be in a ultraviolet region.
2) The wavelength of the n=4 to n=1.
Putting the values in above equation, we get:
The region of this electromagnetic transition will be in an infrared region.
Lilpeeq's question is legitimate, but I'm going to try to answer without the statements anyway (potentially ill-advised, but here we go!). Nonmetal-nonmetal bonds are more likely to be covalent because their electronegativites are very similar. Ionic bonds form between elements with large differences in electronegativities, and the smaller the difference is, the more covalent the bond is until an element that bonds with itself forms a perfectly covalent bond. Metals form metallic bonds with each other.
EDIT: Basically they have small differences in electronegativity. Thanks for following up on your question!
Hope this helps!
