Apex answer is: A. the solute becomes less ordered
Explanation:
Answer:
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
Explanation:
Mezoic era began 252m years ago and ended 6.6m years ago.
It was a time of geological and biological transition. During this era the continents began to drift to their present configuration.
3 of the largest mass extinction occurred at this era. One which include the dinosaurs.
I hope this helped. :)
Answer:
0.00018M
Explanation:
Mass of the aspirin tablet =0.4g.
% by mass of ASA=68.2
mass of in the tablet=68.2/100×0.4g
=0.2748g
mass conc of ASA=mass of ASA/Volume of diluent(250ml)
=0.2748/0.25
=1.0992g/dm3
molar conc=mass conc/molar mass
=1.0992/180.16
=0.006M
Conc of the stock solution C1=0.006M
Initial volume for making the diluted solution(V1)=3ml
final volume of the diluted solution=100ml
from dilution principle
no of mole=conc × volume
initial conc(C1)×initial volume(V1)=final conc(C2)×final volume(V2)
C2=0.006M×3ml/100ml
=0.00018M
Air is an example of a gas dissolved in a gas.
Air is a <em>homogeneous mixture </em>of oxygen, argon, and several other gases in nitrogen.
