<h2>Answer:</h2>

<u>The right option is</u><u> (B) S orbital</u>

<h2>Explanation:</h2>

Each orbital can hold two electrons. One spin-up and one spin-down. The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons.

The order in which the orbitals are filled is given below

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s

You are analyzing a solid isolated from a reaction and find that its boiling point is over 1000 ∘ C . You dissolve the compound

babymother [125]

Answer:

Sodium iodide NaI

Magnesium chloride MgCl₂

Explanation:

Silicon dioxide SiO₂ it is not soluble in water, so it can not be recrystallized from water, it is a white solid and the boiling point is 2230 °C. This one is not the unknown solid.

Sodium iodide NaI it is soluble in water, it has a white color and the boiling point is 1304 °C . This can be the unknown solid.

Magnesium chloride MgCl₂ is soluble in water, it have a white color and the boiling point is 1,412 °C . This can be the unknown solid.

Phosphorus tribromide PBr₃ is will start a hydrolysis reaction in water, it is a colorless liquid and it has a boiling point of 173 °C. This one is not the unknown solid.

What does the specific heat for a substance indicate?

o-na [289]

O the amount of heat required to increase the temperature of 1 gram by 1°C

Explanation:

The specific heat of a substance is the amount of heat required to increase the temperature of 1 gram of a substance by 1°C. It is an intensive property that is specific to every substance.

The unit is given as J/g⁻¹°C⁻¹ or J/g⁻¹K⁻¹

This related to the quantity of heat using the expression below:

Q = mC∅

Q is the quantity of heat added

m is the mass

C is the specific heat

∅ is the temperature change.

A system contains bonds between particles. Which choice describes the microscopic structures of the energy in this system? There

borishaifa [10]

Answer:

The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>

Explanation:

Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
