Answer:
a. KCl, c. BaCl2 and e. LiF.
Explanation:
Hello,
In this case, we can identify the ionic compounds by verifying the difference in the electronegativity between the bonding compounds when it is 1.7 or more (otherwise it is covalent) as shown below:
a. KCl: 3.0-0.9=2.1 -> Ionic.
b. C2H4: 2.5-2.1=0.4 -> Covalent.
c. BaCl2: 3.0-0.8=2.2 -> Ionic.
d. SiCl4: 3.0-1.8=1.2 -> Covalent.
e. LiF: 4.0-1.0=3.0 -> Ionic.
Therefore, ionic compounds are a. KCl, c. BaCl2 and e. LiF.
Regards.
Answer:
Drought
Explanation:
It would get really dry because no moisture and the lakes would dry up bc of lack of water
It requires more energy to boil an substance than to melt it (with special exceptions). When something is boiled you are furthering the distance between the already stretched out molecules which will require more energy to do so, also in most cases you will be creating a vapor from boiling which has a high kinetic energy value.
