Answer:

Endocardium is the inner most layer of heart containing tissue that lines the heart chamber and the outer most layer of the heart is called epicardium.
The main function of this structure is to protect the valves and heart chamber.
The endocardium consists of endothelial cells that controls myocardial function.

Answer:
7.8 moles are needed.
Explanation:
Given data:
Mass of oxygen produced = 125 g
Number of moles of mercury oxide needed = ?
Solution:
Chemical equation;
2HgO → 2Hg + O₂
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 125 g/ 32 g/mol
Number of moles = 3.9 mol
Now we will compare the moles of oxygen with mercury oxide.
O₂ : HgO
1 : 2
3.9 : 2×3.9 = 7.8 mol
