Answer:
no
Explanation:
protons and electrons are equal to atomic number
Answer:
0.2mol/kg
Explanation:
molality is the concentration of a solution in moles of solute per kilogram of solvent
moles of solute (NaOH) = 2moles
mass of solvent in kg. =10kg
Therefore molality. = 2moles/10 kg
=0.2mol/kg
The correct answer is option D. i.e.<span>All states of matter show random motion of particles.ding to the kinetic theory
According to the kinectic theory of matter, all the particles show random motion at the room temperature. Decreasing the temperature to absolute zero temperature i.e. 0 K will cease the motion of particles.</span>
