1) chlorine melts at -1101°C and boils at -35°C. what will be the physical state of chlorine at -156°C?
2) which compound contain a polar covalent bond? NaCl, H2, HCl
3) body fluids are approximately 0.90% by mass sodium chloride and have a density of 1.05 g/mL. what mass of sodium chloride is in 4.0 L of body mass?
clear explanation would be highly appreciated. thanks
