A student prepared two beakers with identical sprigs of a water plant as shown in the figure below. She placed one beaker in the shade and the other beaker beside a fluorescent lamp. She then systemalically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.

Arterial blood pressure is traditionally measured in mm Hg. And the style pressure of 85 mm Hg it’s considered borderline between normal and high blood pressure convert this pressure to kPa units. ( 1atm =760 mm Hg= 101.33 kPa )
Determine the net force necessary to give an object with a mass of 2.0 k an acceleration of 5.8 m/s
The molar mass of a liquid is determined by the Dumas method. How is the calculated molar mass of the liquid affected - too high, unaffected or too low, if the student assumed the volume of the flask was 150ml ( as marked on the side of the flask) rather than measuring the volume experimentally ?
Water is not the only chemical contaminant that can be removed from liquids and gasses using molecular sieves. Ammonia, for example, can be removed from gaseous samples using the same 3Å molecular sieves that we used to remove water from ether. Other common contaminant gasses like sulfur dioxide, dihydrogen sulfide and ethylene, however, cannot be removed using 3Å sieves. They can only be removed using 4Å molecular sieves. Explain why this is so.
