<span>The rate of effusion of a gas is inversely proportional to the square root of the molecular weight of the species. Now there will be differences among isotopomers but neglecting these and taking the avg mol wt of N2 = 28 and Xe = 132;
Rate(N2)/Rate(Xe) = sqrt (132/28) = 2.17</span>
Answer:
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.
Explanation:
Answer:
Cohesion
Explanation:
Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
2 days. 20 grams of carbohydrates
Answer:
A lot
Explanation:
- As you go down a group, the elements get larger in size
- All of the elements of the same group have the same # of valence electrons
- As you go to the right of a period, the # of electrons in the outermost shell increases
- The elements at the top right of the table have the highest electronegativity
- Groups 13 through 17 are nonmetals
- The last group contains noble gases
etc.
