Answer:
Germanium has the larger atomic radius.
Answer is:
1: Kr.
2: Cl₂.
3: F₂.
4: O₂.
5: N₂.
6: He.
The lighter (smaller) particles move more quickly than heavier (larger) ones at the same temperature.
Calculate molar masses of the compounds:
M(Cl₂) = 70.9 g/mol; molar mass of chlorine gas.
M(F₂) = 38 g/mol, molar mass of fluorine gas.
M(He) = 4.002 g/mol; molar mass of helium.
M(Kr) = 83.8 g/mol; molar mass of krypton.
M(N₂) = 28.01 g/mol; molar mass of nitrogen gas.
M(O₂) = 32 g/mol; molar mass of oxygen gas.
Answer : A. Location A
The seats in location A will experience sound waves with the greatest intensity , because it is closer to the stage .
Answer:
Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster.
