Answer:
When mechanical waves strike a barrier, at least part of the energy of the waves will be reflected back into the media from which they came.
Explanation:
Acceleration= change
-----------
Time
The change in velocity is 4 m/s b/c 7-3=4.
The time taken is 5 s b/c 10-5 = 5.
So its 4/5 which is
0.8 m/s^2.
You're welcome.
Answer:
The molar solubility of SrCO3 will be lower in 0.10 M 0 M Sr(NO3)2 because of Sr2+
Explanation:
The question reflects the phenomenon known in chemistry as common ion effect. Common ion effect refers to the decreased solubility of a solid in a solution that contains an ion in common with the solute.
In the case of our example here, both strontium carbonate and strontium nitrate possess the strontium II ion in common. The presence of this ion in strontium nitrate will decrease the solubility of strontium carbonate in accordance with Le Chateliers principle. Hence the answer.
