Answer:

hund's rule

Explanation:

states that single electrons with the same spin must occupy each equal-energy orbital before additional electrons with opposite spins can occupy the same orbitals (electrons fill empty orbitals before they pair up).

Draw the products of the transformation shown by the fishhook notation. Include any electrons.
andrew11 [14]

Answer:

Explanation:

The question is based on the concept of the cleavage of bonds. In the process of the reaction the breaking of bonds is required. The cleavage of the bonds make the bonded electrons free to involve in the reaction process.

Fundamentals:

The cleavage of the bond can be done in two ways: homolytic or heterolytic. The heterolytic cleavage occurs when the shared electrons of the covalent bond are taken away by either of the atom. The heterolytic cleavage results in generation of the charged molecules. On the other hand, the homolytic cleavage is the cleavage in which the shared pair of the electrons are equally distributed, resulting in generation of free radicals.

Calcium hydroxide reacts with a substance to produce calcium carbonate<br>name the substance
tankabanditka [31]
Calcium Hydroxide (Ca(OH)2) reacts with the Carbon Dioxide (CO2) present in the Air to form Calcium Carbonate (CaCO3) and Water (H2O).

The equation looks something like this -->

Ca(OH)2 + CO2 = CaCO3 + H2O

What is the ratio of Fe+3 ions to O2- ions in a neutral compound?
SpyIntel [72]

In a neutral compound, the charges must balance, the net charge should be zero.

Since the charge of Fe is 3+ and that of O is 2-, therefore, there should be 2 Fe 3+ ions per 3 O2- ions in order to have a net charge of zero.

How many liters are there in 144g of H₂O (g)?<br> What is the mass of 200L at STP of H₂O₂ (g)?
Lisa [10]

Answer:

1. 179.2 L

2. 303.62 g

Explanation:

1. Determination of volume of H₂O (g).

We'll begin by calculating the number of mole in 144 g of H₂O. This is illustrated below:

Mass of H₂O = 144 g

Molar mass of H₂O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mole of H₂O =?

Mole = mass /Molar mass

Mole of H₂O = 144/18

Mole of H₂O = 8 moles

Finally, we shall determine volume of H₂O (g) as follow:

1 mole of any gas occupy 22.4L at stp.

Therefore, 8 moles of H₂O (g) will occupy =

8 × 22.4 = 179.2 L

Thus, 144 g of H₂O (g) occupies 179.2 L

2. Determination of the mass of H₂O₂ (g).

We'll begin by calculating the number of mole of H₂O₂ (g) that occupied 200 L at STP. this can be obtained as follow:

1 mole of any gas occupy 22.4 L at stp.

Therefore, Xmol of H₂O₂ (g) will occupy 200 L at STP i.e

Xmol of H₂O₂ (g) = 200/22.4

Xmol of H₂O₂ (g) = 8.93 moles

Thus, 8.93 moles of H₂O₂ (g) occupied 200 L at STP.

Finally, we shall determine the mass of H₂O₂ (g) as follow:

Mole of H₂O₂ (g) = 8.93 moles

Molar mass of H₂O₂ = (2×1) + (2×16) = 2 + 32 = 34 g/mol

Mass of H₂O₂ =?

Mole = mass /Molar mass

8.93 = mass of H₂O₂ /34

Cross multiply

Mass of H₂O₂ = 8.93 × 34

Mass of H₂O₂ = 303.62 g
