Answer:
Part A
Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population
Part B
The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T
Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.
Part C
At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1

Explanation:
One of the things you look at is how many electrons does the atom has in its outer shell or how many valance electrons the atom has? if the outer shell is full than atoms are more stable and will not usually bond with other atoms.<span>

Answer:
Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including: High blood pressure, heart disease, stroke, liver disease, and digestive problems. Cancer of the breast, mouth, throat, esophagus, liver, and colon.
Answer is: c) CH₄.
<span>Average speed is inversely proportional to the molar mass, ligher molecules travel faster. Calculate molar mass of all molecules:
a) M(O</span>₂) = 2·16 = 32g/mol.
b) M(N₂) = 2·14 = 28 g/mol.
c) M(CH₄) = 12 + 4·1 = 16 g/mol.
d) M(SF₆) = 32 + 6·19 = 146g/mol.
e) M(CO₂) = 12 + 2·16 = 44g/mol.
