neonofarm [45]

Answer:

The correct answers are "They travel slower than P waves", "They result in much ground motion" and " They are produced by P and S waves".

Explanation:

A surface wave can travel through the existing interface between Earth and air, as well as between Earth and water. A clear example of this type of waves are Love and Rayleigh waves. They travel slower than primary waves, produce large movements in the ground and are produced by primary and secondary waves.

Gwar [14]

(a) 485 x 200 mg = 97000 mg of ibuprofen in the bottle

97000 mg x (1g/1000mg) = 97g of ibuprofen in the bottle

97g (1 mol/ 206.5gC13H18O2) = 0.46973 moles of ibuprofen in the bottle

(b) 0.46973 mol C13H18O2 (6.022 x 10^23 molecules/1mol) = 2.8287 x 10^23 molecules of ibuprofen in the bottle
