Sound waves travel faster through liquid water than through air because A.
water is hotter than air.
B. water is less dense than air.
c. the particles of the liquid transfer energy better than the particles in a gas.
D. the particles in the liquid vibrate more than the particles in a gas.

HURRY PLEASE HELP HELPPP

Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster

Explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
