(a)
Interpretation:
The sample of human skin cell is whether a macroscopic, microscopic or particulate matter is to be identified.
Concept introduction:
The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The microscopic matter requires an optical microscope to be seen. The particulate level includes samples of tiny particles that make up matter. The sample of matter at particulate level is too small to be seen with the most powerful optical microscope.
(b)
Interpretation:
The sample of a sugar molecule is whether a macroscopic, microscopic or particulate matter is to be identified.
Concept introduction:
The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The microscopic matter requires an optical microscope to be seen. The particulate level includes samples of tiny particles that make up matter. The sample of matter at particulate level is too small to be seen with the most powerful optical microscope.
(c)
Interpretation:
The sample of a blade of grass is whether a macroscopic, microscopic or particulate matter is to be identified.
Concept introduction:
The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The particulate level includes samples of tiny particles that make up matter.
(d)
Interpretation:
The sample of a helium atom is whether a macroscopic, microscopic or particulate matter is to be identified.
Concept introduction:
The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The microscopic matter requires an optical microscope to be seen. The particulate level includes samples of tiny particles that make up matter. The sample of matter at particulate level is too small to be seen with the most powerful optical microscope.
(e)
Interpretation:
The sample of a single-celled plant too small to see is whether a macroscopic, microscopic or particulate matter is to be identified.
Concept introduction:
The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The microscopic matter requires an optical microscope to be seen. The particulate level includes samples of tiny particles that make up matter.

- Consider the photograph and illustrations of table salt. Do they include a model? Do they include a depiction of matter at the macroscopic, microscopic, and/or particulate levels? Explain your answers.arrow_forwardHeparin is available in a 10 mL vial containing 2500 units/mL. A heparin infusion is prepared by adding 7.5 mL of the heparin stock solution to a final volume of 500 mL of Dextrose 5% in Water. What is the infusion rate (mL/hour) required to deliver a dose of 18 units/kg/hour to a patient who is 6’0” tall and weighs 154 lbs?arrow_forwardWhich piece of equipment would you use to measure 7.10 mL of CuSO4 (aq)?arrow_forward
- What is the difference between (a) mass and density? (b) an extensive and an intensive property? (c) a solvent and a solution?arrow_forwardAt 25 C, the density of water is 0.997 g/cm3, whereas the density of ice at 10 C is 0.917 g/cm3. (a) If a soft-drink can (volume = 250. mL) is filled completely with pure water at 25 C and then frozen at - 10 C, what volume does the ice occupy? (b) Can the ice be contained within the can?arrow_forwardA solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forward
- Which of the following represent physical properties or changes, and which represent chemical properties or changes? You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.arrow_forwardYou receive a mixture of table salt and sand and have to separate the mixture into pure substances. Explain how you would carry out this task. Is your method based on physical or chemical properties? Explain.arrow_forwardThe density of a solution of sulfuric acid is 1.285 g/cm3, and it is 38.08% acid by mass. Calculate the volume of the acid solution (in mL) you need to supply 125 g of sulfuric acid.arrow_forward
