The difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.
<h3>
What is Isotope?</h3>
Isotopes are two or more types of atoms of the same element that have the same atomic number but differs in mass numbers due to different numbers of neutrons in their nuclei.
Argon atom with a mass number of 38 (Ar-38) - number of neutrons = 20
Argon atom with a mass number of 45 (Ar-45) - number of neutrons = 27
Thus, the difference between Argon-38 and Argon - 45 is the number of neurons in their nuclei.

The small flashlight has less inertia and smaller force is required to move it.
According to Newton's first law of motion, an object will continue at rest or in its state of uniform motion unless it is acted upon by an external unbalanced force. This is also called the law of inertia.
The quantity of mass contained in a body is a measure of its inertia. The greater the mass of the body, the greater the inertia and the greater the force required to move the body.
The smaller flashlight has less inertia than the larger flashlight, so it takes less force to change the motion of the smaller flashlight.

<u>Answer:</u> The unbalanced chemical equations are written below.
<u>Explanation:</u>
An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.
The chemical equation for the reaction of nitrogen gas and oxygen gas follows:
The product formed is nitrogen dioxide.
The chemical equation for the decomposition of dinitrogen pentaoxide follows:
The product formed is dinitrogen tetroxide and oxygen gas.
The chemical equation for the reaction of ozone to oxygen gas follows:
The product formed is oxygen gas.
The chemical equation for the reaction of chlorine and sodium iodide follows:
The product formed is sodium chloride and iodine gas
The chemical equation for the reaction of magnesium and oxygen gas follows:
The product formed is magnesium oxide
the room will either cool down or warm up the water until it is the same temperature as the room around it.
Answer:
E°= E°cathode- E° anode= 0.271-0.330= -0.59V
Explanation:
NB: the stoichiometry does not affect E°values,
And the more positive the E° values , the greater it's tendency to become spontaneous and hence irreversible, and the more negative the E° values the more likely to become less spontaneous and reversible, hence the above reaction is reversible
