Much Water Does Epsom salts Contain? Purpose The purpose of the experiment was to find the percent of water in Epsom salts by heating it. To find the percent of water in a hydrate‚ the hydrate must be heated. The experiment did not only show how dehydration occurs‚ but this experiment also gives an accurate and definite portrayal of the amount of water that is removed Background Information A hydrate is any compound that contains water. An anhydrous compound is a hydrate in which the water is taken

Introduction: This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals‚ this project has many names. Following are some of the other names or titles for this project: |Fruit power or fruit battery

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min

Hypothesis: Temperature of water affects the time taken for salt to dissolve Introduction: In this is will be doing a coursework an experiment in which I will be trying to prove my hypothesis? I will do a set of trial experiment and a main one which I will be trying different temperature‚ which I can prove that this will work and to make sure I get hang of it when I do my real experiment. I will also draw a set of graphs in which I can show which can show if this proves my hypothesis. Important

Does Soap Affect the Surface Tension of Water? Background: Surface tension refers to water’s ability to "stick to itself". Surface tensioncan be measured and observed by dropping water (drop by drop) onto a penny. Thenumber of water drops that can fit on a penny will surprise you. Question: How does soap affect the water’s surface tension? Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed

6. Why does the level of water not change when salt is dissolved in water? 7. How can matter change its state? 8. Define boiling. Why boiling is considered as bulk phenomenon? 9. Why does the temperature of a substance remain constant during melting and boiling even when heat is being supplied to it continuously? 10. What is evaporation? Why does evaporation cause cooling? 11. What are the differences between boiling and evaporation? 12. What factors affect the rate of

runoff in the water as it rains. That eventually my end up inside our ponds and lakes. In the case of piper lake‚ a fertilizer plant‚ HTC fertilizers‚ leakes large amounts of fertilizer into eagle river which feeds onto piper lake. Since then algal blooms have been a dramatic increase. We did an experiment to truly if the fertilizer was affecting the algae in the water. In our experiment we had 6 test tubes. Each test tube had a different ratio of algae to fertilizer in the water. Our first test

drowns it means that their lungs (respiratory system) has been blocked from receiving oxygen by a liquid. Majority of the time it is water that people drown in. “Drowning is the third most common cause of accidental death worldwide‚ accounting for 7% of all injury related deaths” (MedicineNet). Water is the most common way that people drown‚ but the two types of water that is common to Earth in masses are freshwater and saltwater. Both can drown you but in completely difference ways. Drowning in saltwater

drinking water? Saltwater is becoming a problem to our drinking water because it is getting into the rivers that we get our drinking water from and it and the saltwater it is also intruding aquifers. The place where you can see the most change is in Florida because of the climate change. Because whenever it floods in Florida the seawater gets into the rivers and also seeps into the grounds. When it seeps into the ground it gets into the aquifers and that’s how Florida is losing its water. It is also
