Answer:
it is less than 1% made up of the world
Explanation:
i hope this helps u out
It has 6 electrons, and 4 valence electrons
C it is C because a geno type is the genetic material that predicts what that feature will look like. A phenotype is how that genotype made you look on the outside.
Answer:
According to Coulomb’s law, the Ca and Se ions have 4 times the attractive force (2+ × 2-) than that of the K and Br ions (1+ × 1-).
Explanation:
From Coulomb's law, the attractive force between calcium and selenium ions is four times the attractive force between potassium and bromide ions.
This has something to do with size and magnitude of charge. Calcium ions and selenide ions are smaller and both carry greater charge magnitude than potassium and bromide ions. This paves way for greater electrostatic attraction between them when the distance of the charges apart is minimal. Hence a greater lattice energy.
Lol it literally says that he covered the distance in three seconds so I believe it would be three
