Question

Which type of bonding does Ba form upon solidification? covalent network ionic metallic molecular When a liquid is heated at its boiling point, the? a covalent bond is broken, allowing vaporization tooccur. temperature of liquid increases temperature of liquid remains the same as long as liquid ispresent temperature of vapor phase increases Red blood cells are placed into pure water. Which of thefollowing statements is true water molecules flow out of the red blood cells, causing them tocollapse water flows into the red blood cells, causing them to swell andburst the osmotic pressure of the cell contents increases, causing thecells to burst the osmotic pressure inside the cells equals the osmotic pressureoutside

the osmotic pressure inside the cells equals the osmotic pressureoutside

Explanation / Answer

   1) Barium (Ba) on solidification formsmetallic bonding .    2) At the boiling point the liquid changesto vapour but there is no change in temperature .     3) when the red blood cells areplaced in pure water the water flows through the membrane in to theblood cells so the cells burst .      the blood cells are 0.9 %salted . So when the blood cells are placed in pure water thewater flows from the lower concentrated side to the highconcentrated side (blood cell ) . So the blood cells burst out .
