A pendulum.  Hold it high and it has potential energy but no kinetic energy because it is still.  As it moves down when you drop it, it changes to kinetic energy and moves faster and faster until it's at the bottom where it has no potential energy.  However, it still has momentum, so now it is changed to potential energy as it moves up the other side

Consider the Bohr Model of Phosphorus below. Which statement is FALSE?
Rudik [331]

Answer:

(C) Energy is released when the electron is ejected from the atom.

Explanation:

In the Bohr model of the atom, electrons are arranged in energy levels. The electrons in the lowest energy levels are nearest to the nucleus. An electron may move from a lower to a higher energy level by absorbing energy that is equal to the difference between the energies of the higher and lower energy level.

The potential energy of all electrons inside the atom have negative values and an electron which is infinitely far from the nucleus has an electrostatic potential energy of zero.

Energy is absorbed when an electron is removed from the atom (ionization). Hence the process is highly endothermic. Therefore it is false to say that "Energy is released when the electron is ejected from the atom."

How many liters of oxygen are required to react completely with 14.8 mol of Al?
Bond [772]

Answer:

296 L  

Explanation:

We will need a balanced equation with moles, so let's gather all the information in one place.

                  4Al + 3O₂ ⟶ 2Al₂O₃

n/mol:        17.4

1. Moles of O₂

n = \text{17.4 mol Al}\times \dfrac{\text{3 mol O}_{2}}{\text{4 mol Al}}= \text{13.05 mol O}_{2}

2. Volume of O₂

You haven't given the conditions at which the volume is measured, so I assume it is at STP (0 °C and 1 bar).

At STP the molar volume of a gas is 22.71 L.

V = \text{13.05 mol}\times \dfrac{\text{22.71 L}}{\text{1 mol }}= \textbf{296 L}
