Which Substance Mixed With Water Produce The Most Hydroelectricity

When two solutions combine and a solid substance is formed, this solid is called a precipitate. In your experiments, if the clear reactant solutions you combined together formed a cloudy product, then a precipitate (solid substance) was formed. Describe the precipitates (according to color and clarity) and the substances that formed them. (18 points) The combinations that formed precipitates in my experiment were MgSO4 and NH3, MgSO4 and Na2CO3, Na2CO3 and CH3COOH.

1) The materials: cup, gummy bear, triple beam balance, water, metric ruler, and pencil were utilized for the experiment.

Students will place a potato cube into a test tube and add 3 ml of H202 into each tube. Then students will wait one minute and record the height in cm of the bubbles and rate how rapidly the solution bubbles on a scale of 0-5. (0=no reaction, 1=slow,……. 5= very fast.)

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

In this experiment, the scientists are testing which amount of zinc mossy would make a few normal cleaned pennies change their colors into silver when they are placed in the boiling solution of zinc sulfate and water and then turn their colors into the brightest yellow (gold) when they are exposed directly to heat,. The independent variables in this experiment are the amount of zinc and zinc sulfate measured in gram and the dependent variables is the shades of yellow (compared in decimal R,G, B code) of the penny after all steps of the experiment. The constant of this experiment will be the temperature of the tap water used to boil the solution, which is 100°C and the temperature of the hot plate used to heat up the silver penny, which is about 300°C. And the controlled of this experiment is the pennies with the brownish color.

Many signs show that a chemical reaction has occurred. Some ways we know there is a chemical reaction are the formation of gas, formation of precipitate, change in temperature, and,or change in color. In part one of the experiment, we know there was a chemical change because of the formation of the white precipitate. We poured the ammonia and water in the flask with alum and water, forming a white, cloudy substance in between the two liquids. The white, cloudy substance between the two is liquids is also known as aluminum hydroxide. The second part of the experiment was very similar to the first, but in the second part we mixed epon salt, water, and ammonia. The precipitate formed from mixing the epson salt, water, and ammonia was called magnesium hydroxide.

It was hypothesized that Cup 3 with the soda water would have the greatest amount of chemical weathering because of the soda water having the highest pH balance at the beginning of the experiment. Seeing that is was the most acidic; would create the most results. After conducting the experiment, the hypothesis was incorrect. After completing the experiment, the results for the soda water ended up being the cup with the second lowest change in mass of the rock. The rocks beginning weight began at 11.7g and ending at 11.6g., resulting in a change of -.01g. The rock that was in Cup 1 with the 50% vinegar solution had the greatest change in mass. The rock weighing at 8.3g, and then weathering down to 7.0g. Cup 1 had a total change of

Please complete the entire experiment as instructed in the lab manual except for any modifications noted below. Fill out the

1. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint.

On arriving for the experiment they were told that they would play he role of the teacher. They were to read a series of words pairs to an individual on the opposite side of a partition. They were to test the individuals' memory by giving him a word and asking him to select the correct matching word from four alternatives. Each time the learner made an error, they were to give him/her an electric shock at the touch of a lever. The individual was strapped into an electric chair while they watched. The teachers had levers in front of them labelled from 15 to 450 volts and switches labelled from slight shock to danger: severe shock to the final ‘XXX'. They were instructed to move one lever higher on the shock generator each time the learner made an error. There were not of course any shocks.

In this experiment, two different reactions will be occurring to see what will be produced in the final product. The first reaction, also known as reaction A, deals with reagents such as 1-butanol, ammonium bromide, ammonium chloride, and sulfuric acid. The ammonium bromide, ammonium chloride, and sulfuric acid are mixed in water and is called the pre-made nucleophile solution. The 1-butanol will serve as the electrophile in the reaction. The second reaction, which is called reaction B, deals with the same reactants but the electrophile is the 2-methyl-2-propanol.

In this lab, a lab group will do multiple tests on water for contrasting ions. Tests confirming the absence or presence of the ion. The lab group will be dealing with five distinct solutions. A control sample, tap water sample, ocean water sample, and a distilled water sample. The group will also use a reference solution. A reference solution is a solution with a firm vigorous existence of the ion being tested. So, It is like an example of what the precipitate should look like when the ion is existent and visible in the water sample. The solution may or may not contain an ion. Compare the results with the performance of the reference sample. Finally, if an ion is present, a chemical reaction will happen, making either a precipitate or a solution

This experiment consisted of four separate parts. The first part was to adjust the balance to make sure it was working properly, and to measure its

Electricity is used everywhere in our lives. Electricity give life to our homes, our television sets, our computers, and other electronic devices. Electricity also is used for charge our batteries, the batteries that keeps our cars running, our control remotes working, our laptops, our flashlights to keep shinning in dark, and even cell phones. Electricity is the energy that can produce sound, light, heat and many more. Many devices and artifacts we use every day, not only in our homes even in the industries, depends on electricity. But, how we get the production of electricity? Well, fortunately I found that hydroelectric is one of the cleanest and efficient
