spillage had not been quantified at the time of reporting, however, speculations indicated that the spillage could have been serious, thus detrimental to the environment and a threat to environmental well-being. CSX went ahead to confirm the leakage of sodium hydroxide from a derailed tanker car…
The purpose of this lab is to investigate animal behaviors by diving into the world of ethology. There are two ways pill bugs will respond to environmental stimuli: Kinesis (non-directional response) and taxis (directional response). Kinesis occurs when organisms (randomly) move around quickly when they’re unhappy and slowly when they’re happy, which is best demonstrated when one lifts up a rock or other material that the pill bugs are under. In contrast to the simpler response that does…
Meta description: Potassium phosphate is a supplement that is used to treat or prevent hypophosphatemia.
Potassium phosphate is an injection supplement used as a preventative in order to remedy low phosphorus in the blood.
Potassium phosphate is an intravenous injection used to prevent or treat hypophosphatemia, low phosphorus in the blood, through the use of a concentrated solution mixture of monobasic and dibasic potassium.
Phosphorus occurs naturally in every cell in the body and…
reaction and are formed when cations and anions intermix in an aqueous solution.3 Some reactions vary based on temperature or solute concentration. The determination of precipitates also come from solubility rules. According to Cooper, almost all sodium, potassium, and ammonium salts are soluble which mean that they will not form a precipitate.1 All chlorides, bromides, iodides, and fluorides, nitrates, chlorates, perchlorates, and acetates, and sulfates are also soluble. The only exceptions are…
Smoked Sea Bass Fish
1. Sea bass – 4-5 lbs, skin-on fillets
2. Water – 1 quarter
3. Salt – 1 cup
4. White granulated sugar – 1 cup
5. Paprika – as per taste
Instructions to follow:
1. Dissolve salt and sugar in the brine over a low heat.
2. Let the mixture set to cool.
3. Take Sea Bass, remove fillets and rinse under running water properly.
4. After rinsing, let the fish rest in brine and kept in fridge for at least 6-10 hours.
5. Preheat the smoker and add the wood…
this experiment is to determine the type of chemicals that are inside the mislabeled bottles.
• pH strips
• 8 bottles of known chemicals:
o silver nitrate
o iron (III) nitrate
o copper (II) nitrate
o sodium iodine
o sodium hydroxide
o nitric acid
o lead (II) nitrate
o sodium carbonate
• 8 bottles of unlabeled chemicals the same contents as known chemicals
• 1 well tray
1. Place 7-10 drops of each chemical (known and unknown) into separate wells in the well tray.

Crystal chemical relationship between quartz (SiO2) and FePO4
Silicon dioxide is an oxide of silicon with the chemical formula of SiO2. SiO2 is a chemical compound most commonly found in Quartz and it has a space group of P3121. The lattice symmetry of SiO2 is tetrahedron, where there are 4 oxygen atoms covalently bonded to the silicon…
The purpose of this experiment was to see if different fragrances affected a soap’s antibacterial properties. In this experiment, non-scented Alconox soap was used as the control. The experimental groups consisted of Joy lemon dishwashing soap, Dawn Escapes New Zealand Springs dishwashing soap, and the soap from the campus bathroom dispenser. The subject’s hands were washed with each of these soaps for approximately 30 seconds with each soap. The subject’s right hand was swabbed for each sample.…
