Percent Composition Of Water In A Hydrate Lab

This experiment is based on determining the chemical formula for a hydrated compound containing copper, chloride, and water molecules in the crystal structure of the solid compound, using law of definite proportion. The general formula of the compound is CuxCly•zH2O, and aim is to determine chemical formula of this compound.

The goal of this experiment was to determine the empirical formula for a hydrate of magnesium sulfate and water. The technique that was used was measure the mass of the hydrate and then apply heat to evaporate the water. Then determine the mass of water that was in the hydrate and the mass of the remaining magnesium sulfate. The equation for the hydrate is determined by calculating the mole to mole ratio of the water and the anhydrous. The resulting formula will be formated as: MgSO4*_H2O

The purpose of this lab was to determine the percent cobalt and oxalate by mass, and with that information, the empirical formula for cobalt oxalate hydrate, using the general formula Coa(C2O4)b.cH2O.

Procedures: First take the timer and set it for 30 minutes. Next take both the candles and light them at the same time. While lighting them have another person press the timer. After the timer go’s off blow out the candles and

You then take scissors or a knife and cut one hole on the side of the turkey baster or car filler. The car filler/ turkey baster should be facing upwards with the open end of the turkey baster facing up with the handmade hole on the side of it. Then you take apart the spark igniter and reassemble it in the turkey baster or car filler so that the part you spin to create the spark is the only part sticking out of the handmade hole. That is when you use the screwdriver and wrench to take apart and put back together the spark igniter. The cannon is finished when the spark igniter is properly assembled and is able to create a spark. To finish the experiment you then need to add ten to fifteen drops of rubbing alcohol inside of the turkey baster or car filler. When you are in a safe open area where no one is around you can then spin the spark igniter knob really fact to create a spark with the rubbing alcohol and launch the ball out of the cannon. The cannon won’t work properly if there is a dent in the ball. The ball won’t launch if there is a dent because the dent allows oxygen to get into the cannon and the combustion won’t work

Once the timer goes off, let the mug sit in the oven till it cools down.

Place the covered crucible into a pipestem triangle, heating gently for 2 minutes. Using a wire tilt the cover to allow air to enter the crucible. Strongly heat the crucible for 10 minutes.

hydration is the process of providing an adequate amount of liquid to bodily tissues. Not only water can hydrate you. Things like, oatmeal, coffee, lettuce, yogurt and things of that sort can hydrate an athlete. They does not give athlete the okay not to drink water.our bodies need water to mostien food and transport nutrients to and from blood cells. They does not give athlete the okay not to drink water. Our bodys can not survive without water. Water is a solvent for out bodys. without out water athletes can become dehydrated ans in fact die. Dehydration occurs when the loss of body fluids, mostly water. When we lose too much water our bodies become unbalanced. Deyhration an come from fevers, heat exposure, and too much exercise. Even when

First, get an handful of chili seeds. Make sure you have already dry it under the sunlight. Second, make small hole on the soil by using the small spade and put the seeds on it then close with soil. Make sure to put it on the open area. Next, wait

The purpose of this experiment is to determine the empirical formula also known as the simple formula of a compund known as a hydrate.
