Answer:
Radiant; electromagnetic; kinetic energy.
Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Light and radio are examples of the radiant or electromagnetic energy form, which is kinetic energy because it is always moving.
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Answer:
Valence electrons: P = 5, O =6, Cl = 7
The Lewis structure is shown below.
Explanation:
To determine the number of valence electrons, we need to find the atom at the periodic table, because the group determines this. P is at group 15 (or 5A), so it has 5 valence electrons, O is at group 16 (or 6A) so it has 6 valence electrons, and Cl is at group 17 (or 7A) so it has 7 valence electrons.
To follow the octet rule, all the atoms must have 8 electrons in the valence shell, so, P must do 3 bonds, O two, and Cl one. So, the most likely formula is P with a single bond with O, and with two Cl, and the other Cl with a single bond with O.
There'll be 1 lone pair in P, 2 lone pairs in O, and 3 lone pairs in each Cl atom, as shown below.
The Lewis structure is done by placing the atoms with their valence electrons represented and then making the bonds, as shown below.
