nitrogen (N), antimony (Sb), bismuth (BI)
Explanation:
Electrical conductance increases from Nitrogen to antimony and then Bismuth. Electrical conductance increases with available free electrons.
- The elements listed belongs to Group V on the periodic table.
- Group V elements are Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth.
- As we go down the group, electrical conductance increases.
- This is because the radius of the atom becomes larger and the pull on the outer electrons become very weak.
- Outer electrons becomes free to facilitate electrical conductance.
- We can also see that metallicity i.e electropositivity increases down the group.

Answer:
The molar mass of the unknown gas is 100.4 g/mol
Explanation:
Step 1: Data given
Molar mass of argon = 39.95 g/mol
After filling with argon the flask gained 3.221 grams
After filling with an unknown gas, the flask gained 8.107 grams
Step 2: Calculate the molar mass of the unknown gas
The gas with the higher molar mass will have the higher density.
Ar - 3.224 g; molar mass = 39.95 g/mol
X = 8.102 g; molar mass = ??
Molar mass of the unknown gas = 8.102g X *(39.95 g/mol / 3.224 g) = 100.4 g/mol
The molar mass of the unknown gas is 100.4 g/mol
Answer: No.
Explanation: Clay is filled with minerals that often weather to create shale. Clay is usually found in muddy environments, so it traps.
You would be most likely to use a slicing machine if you were using the <u>icebox </u>method to produce cookies.
In the icebox method a type of cookie in which the dough is made, rolled into a stick, and refrigerated until the dough hardens. The dough can be removed from the refrigerator, cut into individual pieces, and then baked. The rest of the dough is returned to the refrigerator until needed.
Icebox method, also known as refrigerator cookies, are sliced and baked cookies. The dough is formed into logs, chilled in the refrigerator (also called an icebox), sliced , and then baked.
