Mechanical waves can not travel through regions of space that are void of particles
Answer:
The answer to your question is 5.019 x 10²² atoms
Explanation:
Data
mass of ammonium carbonate = 8 g
number of atoms = ?
Process
1.- Calculate the molar mass of (NH₄)₂CO₃
(NH₄)₂CO₃ = (14 x 2) + (1 x 8) + (12 x 1) + (16 x 3)
= 28 + 8 + 12 + 48
= 96 g
2.- Calculate the number of atoms
96 g ------------------ 6.023 x 10²³ atoms
8 g ----------------- x
x = (8 x 6.023 x 10²³) / 96
x = 5.019 x 10²² atoms
Answer:
D
Explanation:
It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.
