I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.
Hope this helps!
Density Grams or kilograms
Volume is liters milliliters or cm cubed
Answer:
7.07
Explanation:
HA = weak acid = 0.053
A+ = conjugate base = 0.045
Ka = 7.2x10^-8
Ka = [H+][A-]/HA
7 2x10^-8 = [H+][0.045]/0.053
[H+] = 7.2x10^-8 x 0.053/0.045
= 8.48x10^-8
PH = -log[H+]
= -log[8.48x10^-8]
PH = -[login.48 + log10^-8]
PH = -0.928 - (-8)log10
= 7.07
The reason why it is not considered this is because the material was made in a lab, not through nature, which is what is required to be considered as a true mineral.
Answer:
The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving or vibrating in place.
