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.
Have a nice day!
With a pH of five, it would mean that this substance is a weak acid one would also it expect it would be sour.
Answer:
Mole percent of 
in solution is 1.71%
Explanation:
Number of moles of a compound is the ratio of mass to molar mass of the compound.
Molar mass of = 110.98 g/mol
Molar mass of 
= 18.02 g/mol
Density is the ratio of mass to volume
So, mass of 60.0 mL of water = 
Hence, 6.50 g of = 
of = 0.0586 moles of
60.8 g of = 
of = 3.37 moles of
So, mole percent of in solution = \frac{n_{CaCl_{2}}}{n_{total}}\times 100% = 
% = 1.71%
Answer:
0.900 V
Explanation:
Oxidation half cell;
2Al(s) -----> 2Al^3+(aq) + 6e
Reduction half equation;
3Zn^2+(aq) + 6e ----> 3Zn(s)
E°anode = -1.66V
E°cathode= -0.76 V
E°cell= E°cathode - E°anode
E°cell= -0.76-(-1.66)
E°cell= 0.900 V
