Answer:

1.

Chemical formula: CaBr2

Chemical name: calcium bromide (calcium has only one valence, so it isn't necceseraly to name it)

Cation: Ca^2+

Anion: Br^-

Chemical formula: NiO

Chemical name: Nickel(II) oxide

Cation: Ni^2+ (the name Nickel (ii) come from its valence)

Anion: O^2-

Chemical formula: Cd3N2 (notice that the addition of the valences of all elements is equal to zero because compounds are neutral, that is, 3*(2+) + 2*(3-) = 0)

Chemical name: Cadmium(II) nitride

2.

Chemical formula: SiI4

Chemical name: Silicon tetraiodide

Chemical formula: N2O (as it name states, 2 atoms of N and 1 atom of O)

Chemical name: dinitrogen monoxide

Chemical formula: P4O10 (it's actually composed by two molecules of P2O5)

Chemical name: Phosphorus pentoxide

If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, how many isomers would result?
Mandarinka [93]

One isomer is formed

1,1- Dichloroethane is the isomer.

If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, it would result in one isomer.

  • In contrast to 1,2-dichloroethane, which has two chlorine atoms connected to distinct carbon atoms, 1,1-dichloroethane has two chlorine atoms bound to the same carbon atom.
  • Isomers are each of two or more compounds having the same formula but various atom arrangements in the molecule and unique characteristics.

<h3>What three types of isomers are there?</h3>
  • Chain isomers
  • Functional group isomers
  • Positional isomers

These are the three different categories of structural isomers.

<h3>How is an isomer recognized?</h3>
  • Their bonding patterns and the way they occupy three-dimensional space can be used to distinguish them.
  • Determine the bonding patterns of structural (constitutional) isomers.
  • Although the atoms in the compounds are the same, their connections create various functional groups.

<h3>What makes isomers significant?</h3>
  • Because two isomers might have the same chemical formula but different chemical structures, they are significant.
  • The molecule's properties are influenced by its structure.

Lionel places red blood cells in a beaker of pure water, and then he observes their
scZoUnD [109]

Answer:

The red blood cells will burst

Explanation:

When the red blood cells are placed in pure water, they will gain water by osmosis, swell and finally burst due to their weak cell membranes. This process is referred to as hemolysis.

taurus [48]

Answer: sharing

Reason: They do this to gain stability. The reason they don’t actually transfer is because the difference in electronegativity values are above a certain value.
