Displacement is zero. Displacement is in reference to the starting and ending positions, so starting and ending in the same place would cause a net displacement of zero. Distance, however, is not zero. It is a measurement of the total amount moved, so if the object left the starting position, the distance is automatically not zero.
<span>Answer:
The total anion concentration = 6.0 + 2x12.0 + 3.0 = 33.0mEq/L</span>
From the ideal gas equation,

where n is number of moles, R is Universal gas constant, P is pressure, V is volume, and T is temperature of the gas.
The pressure and volume are inversely proportional to each other at constant temperature and number of moles.
Hence, on decreasing the pressure, the volume will increase.
As the hiker reaches a height of a mountain, the pressure would decrease which results in the reestablishment of equilibrium between gas molecules thus resulting in pushing of bag outwards.
Hence, the bag will expand as the hiker reaches the top of the mountain.
The materials which allow heat to pass through them easily are conductors of heat. For examples,aluminum, iron, and copper.
Hope this helps! ;)
