Answer:
2. liver mortis
Explanation:
This is a physical process. While the individual is alive, the heart circulates the blood. When death occurs, circulation stops and the blood begins to settle, by gravity, to the lowest portions of the body. This results in a discoloration of those lower, dependent parts of the body. Although beginning immediately, the first signs of livor mortis are typically seen about 1 hour following death, with full development being observed 2 to 4 hours following death.
The reason copper coins dull in the first place, is because copper reacts with oxygen in the air and form a layer of copper oxide which is a dull greenish-grey colour. When you mix the salt (sodium chloride) with the vinegar (acetic acid) you form Sodium acetate and Hydrogen chloride.
<span>To draw an acceptable lewis structure we must first determine the number of valance elections of the molecule in the ground state, and then adjust the molecule to refect the molecular radial cation after one or more of the electrons have been removed from its outter most shell. The lewis structure should refect the best configuation with good resonance and stability.</span>
Well, considering atoms make up everything, they clearly play a very essential role.
However, this is where we see things like balanced chemical reactions and equations. It tells us how many we need for a reaction to occur, for example 4 atoms of nitrogen, etc.
