Answer:
o processo e de metamorfose. As borboletas e outrostipos de insetos.....
As in relative abundance , one is take reference
So,
One is taken as 1:
Other is subtracted from it:
(1 - 0.6011)(atomic mass of Ga-71)
Equation can be written as:
<span>69.723 = (0.6011)(68.9256) + (1-0.6011)x </span>
<span>(1-0.6011) is the percentage abundance of Ga-71 expressed in percentage: </span>
<span>Solving for x </span>
<span>28.2918 = 0.3989 x </span>
<span>x= 70.9246.......</span>
Answer is: <span>the greater boiling point of 2- propanol is because hydrogen bonds between 2-propanol molecules and more energy is required to breake those bonds.
</span>Hydrogen bond is
an electrostatic attraction between two polar groups that occurs when
a hydrogen atom (H), covalently bound to a
highly electronegative atom such as flourine (F), oxygen (O) and
nitrogen (N) atoms.
Explanation:
If there is a single pair of electrons that bind to nitrogen , oxygen, or fluorine, the bonding to water is plausible. Hence a hydrogen can be accepted. If there is a bound hydrogen to one of the three above-mentioned elements, then it can be donated. The other information is the precense of lone pair of electron.
