Percent Composition Of Water In A Hydrate Lab

First, put the key into the ignation switch where located below the headlight compartment .

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.

At the beginning of the lab, the crucible is heated. What is the purpose of this step? How would your results (mole ratio of anhydride to water) have changed if you did not pre-heat the crucible? Explain. Feel free to use real numbers to

A hydrate is a compound that is bonded with a certain number of water molecules. When heated, the water will be driven out, thus being left with an anhydrate. The anhydrate is the hydrate minus the water. The hydrate must be

A hydrate is a chemical compound containing salt and water. Depending on the salt, there is a maximum amount of water molecules that can be absorbed by the salt. An anhydrous salt is when the hydrate loses water, which happens when the hydrate is heated

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

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.

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

Before using the crucible inspect it to make sure there are no cracks. If there is get another one from the teacher. Clean the crucible and place it on the table without touching it on the inside so no grease from

To begin, place the quinoa in a pot with water, and place the pot on the stove to

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

Let the iron warm for about 10 minutes or until the iron is hot to the

Once the water is at the desired temperature, place the small lamp 5cm away from the beaker and turn it on.

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

Put the potatoes in the hot oil, and always use a medium heat so that the potatoes did not quickly burn.
