Asubstance is boiled repeatedly and stirred, but the solute never mixes with the solvent. which best describes why

Either Solute or solvent may have hydrogen bond in it but another one has opposite. So, in situation of un-like characteristics, they can't dissolve by any means!

Hope this helps!

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings.
