Using bond lengths in Table 9.2 (p. 371) and assuming ideal geometry, calculate each of the following distances:
Fed [463]

<u>158 pm</u> is the distance Between equatorial Fluorine atoms in PF₅<u>(</u>Phosphorus pentafluoride).

<h3>What is Fluorine?</h3>

The chemical element fluorine has an atomic number of 9 and the symbol F. The lightest halogen, it is an extremely poisonous, pale yellow diatomic gas under normal conditions. It is exceedingly reactive and, as the most electronegative element, reacts with all other elements with the exception of argon, neon, and helium.

Fluorine is the 24th most abundant element overall and the 13th most abundant on Earth. In order to decrease the melting temperatures of metal ores for smelting, fluorite, the main mineral source of fluorine, was added. The Latin verb fluo, which means "flow," gave the mineral its name. Fluorite was first described in 1529.

Identify which subatomic particles match each of these descriptions. Specifically, determine whether the following descriptions
iren2701 [21]

Answer:

1. Protons

2. Electrons

3. Neutrons

4. Protons and neutrons

5. Electrons

Explanation:

The protons are the only positive sub-atomic particles and the have a charge of +1.

The Electrons are the only negative subatomic particles and they have a charge of -1

Neutrons do not have any charge but they have the same mass as the protons

The nucleus of an atom is where most of the atomic masses are concentrated and it houses the neutrons and protons

The electrons reside outside the nucleus and they have a much more lesser mass compared to the neutrons and protons

Which statement best describes how an electromagnetic motor works?
inn [45]

Answer:

Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.

Explanation:

Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.

Which of the following best explains why Pangaea broke apart into the modern-day continents?
Oksana_A [137]

Answer:

C. Balanced forces caused a change in the motion of the plates.

Explanation:

Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.

Small quantities of oxygen can be prepared in the laboratory by heating potassium chlorate, KClO3 ( is ) . The equation for the
gayaneshka [121]

Answer: 25.89g of O2 (g)

Explanation:

We begin by finding the molar mass of compounds of interest in the given equation. 2 KClO3 ⟶ 2 KCl + 3 O 2

1  mole of KCLO3 = 39 .10 + 35.5 + (3x16) = 122.55g, 2Moles would be 2 x 122.5 = 245.1g

1 mole Oxygen gas = 32g, 3 moles would be, 3 x 32= 96g

According to the equation;

245.1g of KCLO3 produces 96g of O2 (g)

If 1g of KCLO3  produces  96÷245.1  of O2 (g)  from heating.

66.1g of KCLO3 would produce; 96÷245.1  x 66.1 = 25.89g of O2 (g) from heating.
