equations helps us mathematically see what is happing during the reaction besides performing and watching it occur. Being able to identify the limiting reagent, products produce, and solve for molarity is key to chemical analysis. Performing the experiment is just half of the equation in chemical analysis. This lab did not have many safety precautions except there was an open flame…
to the heated substrate surface as in of chemical vapor deposition as shown in fig. Droplets after collision with heated substrate changes into powdered form. The droplets closer to the heated substrate but not in actual contact improves the efficiency of film growth (Perednis D.…
Mole to Mole relationship and Empirical formula of a Hydrate
The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner.
Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for…
• The temperature in the room may have altered.
A dependent variable is a variable you do not change during an experiment. Instead, it changes as a result of other changes you make.
The dependent variables in my experiment were:
• The rate of reaction.
• The volume of sodium thiosulphate.
The volume of sodium thiosulphate will remain unaffected throughout the whole experiment, Where as I will be changing the concentrations of hydrochloric acid. The volume of sodium thiosulphate will…
significant importance to the world economy, the human body, and the environment, copper has been studied and manipulated to explore its uses and properties. In the experiment performed, the copper cycle was observed by placing copper through a series of chemical reactions to demonstrate the different reaction types.
Materials and Methods
To begin the experiment, a 50 mL beaker was placed on a hot plate with a ring stand along with a fume hood made out of a funnel, rubber tubing, and an…
Elephant’s Toothpaste Experiment
A chemical reaction is a process in which atoms of the same or different element rearrange themselves to form a new substance. There are 7 ways to tell if a chemical reaction has occurred; if there are gas bubbles forming, if a precipitate is forming, if the colour has changed, if the temperature has changed, if the volume has changed, if it is giving out light and if there is a change in smell or taste. In a chemical reaction heat is either…

TITLE: Decomposition reaction: hydrogen peroxide (H2O2) decomposed into hydrogen and oxygen ( H2 and O2)
QUESTION: How will changing the concentration of hydrogen peroxide affect the rate of reaction, that is represented by the increase in pressure over time?
Introduction: Hydrogen peroxide is a chemical compound of hydrogen and oxygen. It is a very strong oxidant but weak in water solution. Hydrogen peroxide decomposes into water…
1. The primary reaction catalyzed by catalase is the decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation.
sulphate is a relatively stable material. It is a widespread natural resource and therefore the cost would be quite low even if the demand is high.
Through the thermodynamic analysis, it seemed that CaSO4 can be used as a promising oxygen carrier for chemical looping combustion.
High heating rate leads to the increase of the initial reacting temperature. The initial reaction starts from 830 ℃ with heating rate of 5 ℃ /min, 930℃ with heating rate of 20 ℃ /min.
Kinetic parameters of reductive…
Calcium chlorate is a very dangerous chemical. It has the ability to harm whoever is around it. It is important to be extremely cautious and pay close attention to what you are doing when working with this product. This chemical may seem a bit scary because of the negative effects it can have on a person, but there are good things about it too!
Calcium chlorate is produced on an industrial scale. It is produced by the chlorination of milk of lime. It is produced by passing chlorine gas through a…
