.700 moles of an unknown solid is placed into water to make 150.0 mL of solution. The solutions temperature decreases by 8.41 degrees Celsius. Calculate delta H, in kj/mol, for the dissolution of the unknown solid. (The specific heat of the solution is 4.184 J/g• degree Celsius and the density of the solution is 1.02 g/mL).

the answer is 303.15 or 303

your answer is c) plasma

~*"auba14"*~

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
