Answer:
Molarity is halved when the volume of solvent is doubled.
Explanation:
Using the dilution equation (volume 1)(molarity 1)=(volume 2)(molarity 2), we can demonstrate the effects of doubling volume.
Suppose the starting volume is 1 L and the starting molarity is 1 M, and doubling the volume would make the final volume 2 L.
Plugging these numbers into the equation, we can figure out the final molarity.
(1 L)(1 M)=(2 L)(X M)
X M= (1 L x 1 M)/(2 L)
X M= 1/2 M
This shows that the molarity is halved when the volume of solvent is doubled.
Answer:
Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.
Arrow and line diagrams show the spin of electrons and show every orbital.
Written configurations require minimal space and show the distribution of electrons between subshells.
Explanation:
B) land cools off much faster than water (creating a air region of high density above land and lower density above sea)
Potassium would not have similar properties because it is the alkali metals, not alkali earth metals
