Experiment 5: Percent Water in a Hydrated Salt Chemistry 1300 Instructor: 2/8/12 Abstract: The purpose of this experiment was to determine the percent by mass in a hydrated salt‚ as well as to learn to handle laboratory apparatus without touching it. The hydrated salt‚ calcium carbonate‚ was heated with high temperature to release water molecules. Gravimetric analysis was used in this experiment to determine the percent by mass of water in a hydrated salt. The hypothesis of this experiment

Marisela Andrade The Effects of Salt Water on Gummy Bears Facilitated diffusion depends on passive transport. Molecules cross cell membrane by diffusion. A type of diffusion is osmosis. If no energy is input into the system during diffusion‚ the molecules will reach a state of equilibrium. The purpose of this experiment was to study why the death occurred among those who drank salt water. Two blue gummy bears had a height of 2 centimeters each. The mass of these gummy bears together were

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Fresh water always freezes at 0℃‚ but that is not always so for water with salt inside. The higher amount of salt there is in the water‚ the more the freezing point decreases. So‚ salt water freezes later than freshwater. The exact measurement of how they impact each other is this: every 5 psu increase‚ the freezing point decreases by 28%.. In an ocean‚ there is frazil and brine. Frazil are ice crystals suspended in water‚ and they are made of nearly pure freshwater. Frazil is the first stages of

Kress Fugl Mrs. Baines S5ENA Physics 8/2/15 Lab Report Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not

In the beginning salt water and regular water got along. They all lived in the same ocean and each droplet would live in harmony. They shared the undersea environment with all the fish and sea plants. Some plants and animals needed salt water more than fresh water and some needed fresh water more than salt water. This is where the problem all started. The fresh water began to become jealous because the salt water was mocking the fresh water about them being the best type of water. It started out
