Answer:
The answer to your question is the number 4. 1.53175 L
Explanation:
Data
Volume 1 = V1 = 557 ml
Concentration 1 = C1 = 11 M
Volume 2 = V2 = ?
Concentration 2 = C2 = 4 M
Formula
Volume 1 x Concentration 1 = Volume 2 x Concentration 2
or V1 x C1 = V2 x C2
Solve for V2 V2 = V1 x C1 / C2
-Substitution
V2 = (557)(11) / 4
-Simplification
V2 = 6127 / 4
-Result
V2 = 1531.75 ml or 1.53175 L
Conclusion
557 ml of 11 M must be diluted to 1.53175 L
Answer:
For the Ag ground-state ion, the type of orbital from which an electron will need to be removed to form the ion of greater positive charge is :
<u>s-orbital</u>
Explanation:
Naming of orbitals :
s = s-orbital
p = p-orbital
d = d-orbital
The electronic configuration of Ag is :
The Outermost shell = 5s
so electron should be removed from 5s . there is only 1 electron in 5s -shell. Hence , Ag exist +1 oxidation state.
According to Aufbau's Rule : Electron will be filled first in lower energy orbital.
The electron should be removed first ,from the higher energy orbital.This is because high energy orbitals are away from the nucleus and can be easily removed. The outermost electron feel less attraction of the nucleus
Ionization energy : Energy required to remove the electron from the outermost shell of the element in the gaseous state.
Hence it will form Ag+ cation
<u>Ag+:</u>
Outer shell is removed after loss of electron.
Answer:
They are fossil fuels because they were formed because of fossilized remains of animals and plants that lived many years ago. They also have a high carbon content.
Moving air has kinetic energy. Anything that has kinetic energy has the ability to do work. Wind turbines change the kinetic energy of the wind into electrical energy. This form of energy production is also free of pollution
