1.one substance must dissolve another : the solvent breaks the the solute causing it to dissociate into the solvent it can be both solids or gases that dissolve in the solute
2.the melting point will be higher than 100 degrees as the salt causes the solution to gain a higher melting point
3.either released or absorbed : energy is required to dissolve the solute but the solute may also release energy
4.the salt dissolved most quickly in the warm water : as there is more energy for the solute to dissolve
hope that helps
They are both made up of the same protein called "histones".
Idk tbh srry man am in quarantine so I have a big packet to do
First off, you should be looking at the whole world, not just the northeastern US. Are other regions warming? Can you provide proof that simply because the northeast received a lot of snow and low temperatures, climate change is not a viable theory?
