Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
Equal volumes of equal concentrations of strong acid and strong base are mixed. Because the volumes and molarities are equal, the number of mole NaOH and HCl are equal.
From reaction
HCl + NaOH ---> NaCl +H2O
we can see that if number of moles HCl and NaOH are equal, they will react completely, and no acid or base is going to be in solution anymore.
So, pH=7.
This cycle is called the Rock Cycle.Igneous Rocks: form by crystallizing melted material (magma). They canform either on the surface (extrusiveigneous rocks), or deep in the crust (intrusive or plutonic igneous rocks). Volcanoes are places where magma erupts as lava or ash.
