<span> B. produces as much energy as cell respiration. i am pretty sure that is the answer</span>
Given the mass percentage of Manganese in a normal healthy body is
It means that g Mn is present in 100 g of the body mass.
Given that the person weighs 196 lbs
Converting the person's mass to g: The conversion factors to be used are: 1 kg = 2.205 lb; 1 kg = 1000 g
Calculating the mass of Mn in the person's body:
Therefore, 0.116 g Mn is present in a person weighing 196 lbs.
Answer:
a. Tellurium
b. Rubidium
c. Argon
d. Astatine
Explanation:
a. An element of the same family as oxygen corresponds to group 16 or 6A, its most stable ion is -2, therefore if the ion has 54 electrons the neutral element should have 52 electrons and also 52 protons. Tellurium
b. The ions from alkali metals are +1, therefore the neutral elements have 1 more electron and proton, since the ion has 36 electrons the neutral element has 37. Rubidium
c. This is direct, look for the element with Z = 18. Argon
d. This is also direct, look for the element with Z = 85. Astatine

Motion can simply be defined as the change in position of a body while energy is the ability or capacity to work.
Mechanical energy is one of the forms of energy and is subdivided into potential energy and kinetic energy. These energies are energies that determine whether a body or an object is moving or not.
When a body is in a position, the energy possessed by such body by virtue of its position is known as potential energy while when a body is moving (in motion), the energy possesses by this body by virtue of its motion is the kinetic energy.
For instance, a ball rolling down an inclined plane is initially at rest at the top of the incline showing that the body has maximum potential energy and zero kinetic energy (since the body is in a position at this point).
As the ball rolls down the incline, it gains momentum and its kinetic energy keeps increasing along the plane while the potential energy keeps decreasing. Once the body gets to the bottom of the plane, the kinetic energy becomes zero while the potential energy is at maximum (because the body is at rest at this point as well).
