Answer:
Solvent
Explanation:
Many people use the solute to describe the solid being dissolved and the solvent to describe the thing doing the dissolving, but really solvent means the part of the solution with a greater amount/concentration.
For example, if you have 1 gram of salt in 10 liters of water, the water is the solvent.
Explanation:
Cause the clumps are so compacted together that it is harder to brake apart but the one that are separated are easy cause they do not have all the pressure on them and when they go to add reaction it is faster
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?
Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg
answer: the mass of the object is 15 kilograms.
