Answer:
The reaction mentioned in the question is a decomposition reaction.
Explanation:
Decomposition reaction is a specific type of chemical reaction in which the reactant molecule undergo break down to generate its respective products.
NaCl ⇒ Na + Cl2
In the above reaction sodium chloride(NaCl) undergo decomposition or break down to generate Sodium(Na) and chlorine gas(Cl2).
Answer:
Explanation:
The kinetic molecular theory of gases depicts the characteristics and behavior of the gases in function of its particles (atoms or molecules).
As stated per the kinetic theory, a gas is consituted by a large amount of tiny particles in rapid random motion.
As result of this rapid continous motion, a huge number of particles are colliding at any moment against the walls of the vessel that contains the gas. The <em>gas pressure</em>, then, is the result of the force that the particles of gas exert over the walls of the container.
As per definition, the net force of may particles divided by the area gives the pressure: P = F / A.
So, the pressure is the force per unit area, which permits you to complete the sentence:
<em>Gas pressure results from the force exerted by a gas per </em><em><u>unit area.</u></em>
The atomic number (6) represents the number of protons in an atom. protons are usually equal to electrons unless the atom is forming a bond or has a charge of some kind on it. Therefore, I believe the correct answer is letter "a". 6 electrons. Any questions?
