Answer:
Carbonyl
Explanation:
While the diagram is slightly unclear, the molecule most likely being shown is a carbonyl. A molecule is a carbonyl when there is a carbon double-bonded to an oxygen.
Answer:
Part A: 36 MBq; Part B: 18 MBq
Explanation:
The half-life is the time it takes for half the substance to disappear.
The activity decreases by half every half-life
A =Ao(½)^n, where n is the number of half-lives.
Part A
3.0 da = 1 half-life
A = Ao(½) = ½ × 72 MBq = 36 MBq
Part B
6.0 da = 2 half-lives
A = Ao(½)^2 = ¼ × 72 MBq = 18 MBq
Answer:
I think that it it correctly balanced that is my opinion and, because the way it is set up, that the answer will tell you weather or not it is correctly balanced or not.
Janes brother Jack is actually correct, underground water seeps into little holes or spaces between the soil and the rocks.
<h3>Underground Water</h3>
Simply put, underground water is found in between soils and crack, another name for this is called aquifers were water is found.
It should be noted that underground water are found at varying levels depending the terrain.

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>
