Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Options 1st and 5th are the right answer.
Fine-grained textures commonly signify magma that quickly reduced at or near the surface of the earth. Quick cooling limits crystals from developing very big. In simple terms, texture associates to how big the single mineral grains are in the ultimate, dense rock. In most of the cases, the resulting grain dimension depends on how fast the magma chilled. 1 mm is the cutoff separating fine- and coarse-grained composition.
When using the fifo method correctly the food stored in front is the food with the earliest use-by dates be stored.
FIFO is the first in, first out method of inventory valuation is a cost flow assumption that the first goods purchased are also the first goods sold. In most companies, this assumption closely matches the actual flow of goods, and therefore considered the most theoretically correct inventory valuation method.
Answer: evolution only leads to increase in complexity when complexity is beneficial to survival and reproduction.
