Answer: option 4. polar, with the chlorine end having a partial negative charge.
Explanation:
1) A polar bond is a covalent bond in which the electrons are pulled more strongly by one of the atoms and then they are not evely distributed between the two linked atoms.
2) That happens when the two atoms have diferent electronegativities.
3) As the per periodic table trend of the electronegativity, you can predict that the electronetativity of Cl is higher than that of P.
In fact, in a table of electronegativities you can find that the electronegativity of Cl is 3.16 while the electronegativity of P is 2.19.
This is a 3.16 - 2.19 = 0.97 difference.
As explained, that difference means that Cl will pull the electrons more strongly resulting if a partial negative charge on Cl and a partial positive charge on P, i.e. a polar bond.
An element cannot be broken down any further. Elements can be found on the periodic table
Answer:
The correct answer is : It can help cones to open and release seeds.
Explanation:
- Gymnosperms like Conifers and Pines grow in high altitudes under extreme weather conditions.
- Higher altitudes have severely cold climate accompanied with water mostly remaining in the ice form.
- This is the reason why the cones produced by these plants are too hard to be destroyed by the extremely harsh conditions.
- But during germination these cones need to open and release the seeds.
- The best natural way for this is by the means of fire which burn the outer harder layer of the cone and release the seeds.
Answer: Both males and females have sharp, curved horns extending from the sides of their heads which are used to defend themselves against predators.
