In addition to solid, liquid, and gas, we also have plasma. Plasma, the "fourth state," ischaracterized by lack of shape, and it cannot be classified as gas, liquid, or solid. Examplesof plasma are plasma ball and the contents of a fluorescent bulb.The fifth state has already been discovered by scientists. It is called Bose-EinsteinCondensate (BEC), but in Grade 3, the focus of study is only on the three states of matter:solids, liquids, and gases.Let us have some exercises on grouping of matter.Grouping Solid MaterialsescrucCan you classify/group the following solid materials.according to their characteristics?Put your answers in the second column of the chart.Inevspoon -#-S-m.steel chair - H-rubber bandE-mgarter -M-EtableE-Helectric drill-Hrigsoft rock -pencil B-plastic glass -H-B blon pin - HeraserE-Bclay pot - M-BSolid MaterialsPropertiesPinPencil.Fubber bandsHardnessBrittlenessElasticityMalleabilityStrengthGrouping Solids, Liquids, and GasesMatter is everything around you.

Thiopental is a general anesthesia that takes effect within a minute. Suppose 75 mg of thiopental in a 25 mg/m solution is slowly induced in an adult patient over a period of 30 seconds. What is the flow rate of thiopental in units of milliliters per second? ml per second
In your first paragraph you should explain the theory of chromatography in general, and the behind thin layer chromatography in detail. a) Define the terms "stationary phase" and "mobile phase" and describe how the stationary phase and the mobile phase interact with the analyte during a chromatographic separation (for chromatography in general – the same concept applies to thin layer, column, and gas chromatography). b) For what two main reasons would a chemist perform a thin layer chromatography analysis? c) define and describe the process of thin layer chromatography. Include the following terms: marking, spotting, developing, visualizing, and measuring. Include in your description several different ways that the plates can be visualized.

Percentage of activity remaining: %
If you have a sample of unknown composition, a first step at analysis might be a determination of the masses of the atoms and molecules in the sample. A mass spectrometer to make such an analysis can take various forms, but for many years the best technique was to determine the masses of ionized atoms and molecules in a sample by observing their circular paths in a uniform magnetic field, as illustrated is shown. A sample to be analyzed is vaporized, then singly ionized. The ions are accelerated through an electric field, and ions of a known speed selected. These ions travel into a region of uniform magnetic field, where they follow circular paths. An exit slit allows ions that have followed a particular path to be counted by a detector, producing a record of the masses of the particles in the sample. The moving ions can be thought of as a current loop, and it will produce its own magnetic field. The direction of this field at the center of the particles’ circular orbit isA. In the…
Heliox is a helium‑oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 5.25 L tank holds helium gas at a pressure of 1734 psi. A second 5.25 L tank holds oxygen at a pressure of 461.0 psi. The two gases are mixed in a 5.25 L tank. If the temperature remains the same throughout the process, what is the pressure of the gas mixture in the tank? Assume ideal gas behavior.
Furosemide is packaged as 10 mg/mL. A pharmacy technician must make a preparation totaling 25 mL of 2 mg/mL concentration. How much drug and how much diluent are used? (Textbook says use %w/v to calculate and the answer key says 5 mL concentrate; 20 mL diluent. I'm looking for how to set up and solve this problem.)
At the hospital, a patient often receives fluids via an intravenous (IV) infusion. A bag of the fluid is held at a fixed height above the patient’s body. The fluid then travels down a large-diameter, flexible tube to a catheter—a short tube with a small diameter— inserted into the patient’s vein. 1.0 L of saline solution, with a density of 1020 kg/m3 and a viscosity of 1.1 × 10-3 Pa ⋅ s, is to be infused into a patient in 8.0 h. The catheter is 30 mm long and has an inner diameter of 0.30 mm. The pressure in the patient’s vein is 10 mm Hg. How high above the patient should the bag be positioned to get the desired flow rate?

Emily Gonzalez is a scientist working for the US military and is currently researching a sarin like chemical that has been found in storage containers sealed inside of a abandoned ship in the Atlantic Ocean. In her lab Emily is hard at work testing the agent and determining its chemical compound, lethal properties, and its ability to aerosolize. During the process Emily's PPE Gown gets caught on the edge of the metal table causing her to slip and fall. As she falls she reaches out to catch herself and knocks over the sealed class tube of this chemical agent. At this point, Emily does not know how well this chemical aerosolizes or if it was able to get inside of her PPE. So she cleans it up following strict protocols and exits the lab to the shower to clean her equipment and herself. As she exits the shower she starts to feel dizzy and cannot hold herself up. Luckily, her lab partner (Sarah) was entering the room and saw Emily almost unconscious lying on the floor. Sarah quickly called…
