Answer:
Here's where orbital hybridization came into play. According to this theory, when the carbon atom is in an excited state, one of the two electrons located in the 2s orbital will get promoted to the empty 2pz orbital. As a result, carbon now has 4 unpaired valence electrons with which it can form four bonds.
Explanation:
K⁺ has positive charge, the easiest way to form a bond is to connect to negatively charged ion. We have only one negative ion Cl⁻.
So, the answer is
C. Cl⁻.
Answer:
15.9gmol⁻¹
The gas could have been methane when we compare the two molecular masses.
Oxygen gas, O₂ also shares this same number for its molecular mass. This would be the reason why it would not be methane.
Explanation:
Given parameters:
Volume of gas at STP = 2.0L or 2.0dm³(1L = dm³)
Mass of the gas = 1.43g
Unknown:
Molecular mass of the gas = ?
Solution
We can find the number of moles using the mole concept according to the equation below:
number of moles = ³⁻¹
number of moles =
number of moles = 0.089mol
Using this obtained number of moles, we can derive the molecular mass of the compound by using the relationship between mass and number of moles according to the equation below:
molecular mass =
molecular mass =
molecular mass of the gas = 15.9gmol⁻¹
The formula of methane gas is CH₄.
Let's calculate the molecular mass of methane using these atomic masses:
C = 12g and H = 1g
The molecular mass = 12 + (1x4) = 16gmol⁻¹
The gas could have been methane when we compare the two molecular masses.
Oxygen gas, O₂ also shares this same number for its molecular mass. This would be the reason why it would not be methane.
Answer:
"The strength of ionization decreases as the proportion including its protons to the excited electrons" is the right solution.
Explanation:
- The ionizing procedure, the creation of ions through manipulating individual atoms or revolutionaries, or through decreasing or increasing charged particles in something other than gas by intense electrical fields.
- It should be the total removal of someone with an electron through an atomic nucleus rather than from molecules. The corresponding molecule has denominated an ion.
