Acid house

Behavioral measurements. Force swimming test (FST). Each mouse was placed into a 20cm diameter glass cylindrical beaker that was filled with warm water (25-30°C) and allowed to swim freely for 6 min. All the experiments were recorded by video. We analyzed the immobility time in last 4 min. Tail suspension test (TST). Each subject was suspended at a hook with tape for 6 min and recorded by video. The immobility time was analyzed in last 4 min. Elevated plus maze (EMP). In the beginning of the…

Bernardi et al., (46) assessed nanoparticle calcium carbonate (NPCC) by means of transmission electron microscopy and the effects of NPCC addition to MTA in regard to the setting time, dimensional change, compressive strength, solubility and pH. , The experimental groups were G1 (MTA), G2 (MTA with 5% NPCC) and G3 (MTA with 10% NPCC). The tests followed ISO and ADA standards. The dimensional change and compressive strength tests were measured immediately after setting, after 24 h and after 30…

Much of the workflow for ceramics production remains the same over the many years this art form has been practiced. When centuries ago, a potter starting the process workflow of producing a ceramic mug (or more likely a jug), he would go to a river bed and collect the clay. Now, Angel Pottery’s supplier is currently a clay supplier in Amherst, Massachusetts. In this supplier’s factory, they use mixing augurs to produce the raw material clay. From factory to home factory, the clay bags are…

cause of acidity in water. Photosynthesis, respiration and decomposition all contribute to pH fluctuations due to their influences on CO2 levels. While carbon dioxide exists in water in a dissolved state, it can also react with water to form carbonic acid H2C0. It is mostly inferred that the area is surrounded by lots of eco systemic processes with lots of plant…

1) The samples that would float on water are water (if in an ice form), oil, methanol, 2- propanol and lead because these materials are less dense than water, which leads to them laying on top, or until they dissolve. The samples that would sink in water include aluminum and copper because they are denser than water. 2) The order of the four liquids that I would layer them in a graduated cylinder from bottom to top consist of: water, oil, 2- propanol, and methanol. 3) Working with specific…

people take to help with an imbalance of the pH of their stomach acid because it neutralizes the gastric acid present (Antacids | Drugs.com). Although the is not just one brand of antacid that is available to people, and most people want to take the best antacid that will help with their acid imbalance. In our lab, we were given the question of which antacid out of the antacids provided to us was the “best” at neutralizing stomach acid. To answer that question me must first establish what makes…

Comparing the masses, after and before reaction Aim To determine if mass is preserved in a chemical reaction conducted with vinegar and Sodium bicarbonate. Hypothesis: The mass of the flask and vinegar after the reaction will be less due to the fact that it is losing the gas which is being produced when the elements are mixed. However part B will be altered as the gas will be preserved inside the balloon. Apparatus  Balance  Sodium bicarbonate  Spatula  Measuring cylinder  2 conical…

1. Do supplements that contain a higher protein content have a lower sugar content? 2. Biuret’s Reagent is a chemical indicator that detects protein and turns violet with the occurrence of peptide bonds. Lugol’s reagent is a chemical indicator that detects starch and turns into a black brown color as a result of the formation of polyiodide chains. Benedict’s reagent is a chemical indictor that detects monosaccharides and sugars and the observed change for a positive reaction is precipitation.…

Almost all of us have to deal with cough and cold, especially during winter time, which can be really annoying, but beside that, if you don’t treat them properly and on time, they can turn into an extremely irritating and dangerous disease. Dry cough is really annyoing and uncomfortable which makes you feel worse than you should. In most common cases, the people with cold and cough are always seeking for pills and syrups in the pharmacies. Probably, they don’t know that there is easy and…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…
