Find ionic compounds ​

Chemistry
1 answer:
ella [17]3 years ago
3 0

Answer:

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

  • This is because metal cationic atom has two valence electrons.
  • Non-metal anionic oxygen has six valence electrons
  • Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
  • Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
  • So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.

When a plant is entering the Calvin cycle of photosynthesis_____.
Andrei [34K]

B). light energy is not required to proceed

Explanation:

In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.

  • During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
  • During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
  • The cycle is also known as dark reactions.
  • It is at this stage that carbon dioxide combines with water to form glucose.
  • The reaction is initiated with light energy which produces NADPH and ATP.
  • The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.

When molten sulfur reacts with chlorine gas, a vile-smelling orange liquid forms that has an empirical formula of SCl. The struc
egoroff_w [7]

Answer:

The structure is shown below.

Explanation:

The formal charge (FC) is the charge that is more close to the actual charge in the real molecules and ions. It can be calculated based on the number of valence electrons (V), the shared electrons (S) and the electrons in the lone pairs (L) by the equation:

FC = V - (L + S/2)

Sulfur is in group 16 of the periodic table, so it has 6 valence electrons, and chlorine is from group 17 of the periodic table, and so it has 7 valence electrons. Chlorine can share only one electron, so it is stable. Sulfur can expand its octet (because it's from the third period) and can have more than 8 electrons when stable.

The possible formulas, from the empiric one, are:

SCl, S₂Cl₂, and S₃Cl₃.

To have FC = 0, chlorine must done only one bond, because S = 2, and L = 6, so:

FC = 7 - (6 + 2/2) = 0

So, it can not be the central atom of a structure. In the SCl, it will hav only a simple bond, so for sulfur, S = 2, and L = 4 (only the lone pairs are counted)

FC = 6 - (4+ 2/2) = +1

For S₂Cl₂, the two sulfurs must be bonded to a simple bond, and each one to one chlorine, thus, for both od them S = 4, and L = 4. so

FC = 6 - (4 + 4/2) = 0

So, it is the correct structure. The lewis structure represents the bonds by lines and the lone pairs of electrons by dots, and it is shown below.
