As the H bond of the butanol is more effective and strong than Van der Waals forces of the ether the surface tension in alcohol is more intensive.
So the correct answer is e)
Answer:
be able to meet long term timber needs.
Explanation:
Forest Services has been indicated for a long time the exhaustion of timer in the United States. However, in the recent decade, this trend has shown a reverse. The creation of nuclear energy and other technological developments that bring about drastic changes in our way of life. Gradually, the forest has recovered its trees and plants, and it is anticipated that timber will be available to meet long-term wood needs.

Explanation:
The reaction between magnesium and hydrochloric
acid combine to form a salt of magnesium chloride and release hydrogen
gas. This single replacement reaction is a classic example of a metal
reacting in an acid to release hydrogen gas.
<u>Answer:</u>
<u>Ion</u>
Ion is a charged particle.
A neutral atom contains equal number of positive protons and negative electrons
When an electron is lost or gained the atom becomes a charged particle which is called as an ION.
For example
Na is an atom which contains 11 electrons and 11 protons(= to atomic number)
When Na loses an electron it will have 11 positive proton and 10 negative electron and Thus, Na will become 
, a charge particle which we call it as sodium ion.
Cl is an atom which contains 17 electrons and 17 protons(= to atomic number)
When Cl loses an electron it will have 17 positive proton and 18 negative electron and Thus, Cl will become 
, a charge particle which we call it as chloride ion.
When an ion is positively charged it is called as a cation
When an ion is negatively charged it is called as an anion.
Salt is formed when an acid reacts with a base.
The cation of the base combines with the anion of the acid to form the salt.
HCl is acid and NaOH is a base forms salt NaCl and water.
is an anion of the acid and is the cation of the base combines to form NaCl salt .
and 
combines to form
