Science Investigation Investigation: I have performed an experiment in order to see the effects of varying the concentration of reactants on the reaction between hydrochloric acid and marble chips. Planning: The experiment I have performed involved the reaction between hydrochloric acid and calcium carbonate (marble chips) to produce calcium chloride, water and carbon dioxide. The chemical equation for this reaction is: CaCO 3 + 2 HCl CaCl 2 + H 2 O + CO 2 Background Information: In order for a ...
Graph Of Reaction Rate Vs Concentration

... person to person. For my big measurements of liquid I will use a large measuring cylinder. I will not introduce a catalyst to the experiment neither will I increase the temperature of the liquids by holding their containers too long, and I will keep the area's temperature in which I'm working in constant. To be on the safe side I will try to keep the light intensity the same throughout the entire experiment by working in the shade. Prediction: I predict that as concentration of increases so ...

PLANNING Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions, then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is t...

Reaction Kinetics: Rate of Reaction Of Tertiary-Butyl Bromide Purpose: The purpose of this experiment is to find the order of t-BB graphically, to find the k (rate constant) at 0 C and at room temperature, also to find the Ea (activation energy). Principles: Several different chemical kinetic principles were used in this experiment. The reaction rates of this chemical equation were determined experimentally. This then allowed the reaction mechanisms (i.e. orders of each component, rate constant,...
Photosynthesis Reaction As Co 2
851 words
Colours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1.1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in s...
Reaction Between Potatoes Catalyse On Hydrogen Peroxide
2,922 words
DECOMPOSITION OF HYDROGEN PEROXIDE BY THE ENZYME CATALYSE POTATO. Introduction In the investigation we will be finding out how the reaction between Potatoes catalyse on Hydrogen peroxide (H 2 O 2) can study the effect of concentration on rate of reaction. The potato is the enzyme that will decompose the chemical Hydrogen peroxide. Hydrogen peroxide is a poisonous chemical, which is broken down in to water (H 2 O) and oxygen (O 2). Aim Investigating the decomposition of hydrogen peroxide by using...
Acid Marble Chip Reaction
3,231 words
Aim: Investigate what affects different temperatures of hydrochloric acid have on calcium carbonate. Background Information: For a reaction to take place, collisions must occur between the particles. If the collisions occur more frequently then the rate of reaction will increase. The rates of reactions can be altered in many ways. The variables are: The size of the particles of a solid reactant The concentrations of reactants in solution The temperature The presence of light The addition of a ca...
Marble Chips Into The Conical Flask
934 words
A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid. Task My task is to measure the rate of reaction between marble chips (CaCO 3) and Hydrochloric acid (2 Hcl). Diagram Plan The equipment I will be using for this experiment will be as follows: Conical flask, Delivery tube, Bung, Measuring cylinder X 2, Water trough, Water, Stopwatch, Marble chips, Hydrochloric Acid, water scales, clamp and Retort Stand.! WEAR SAFETY GOGGLES ! I will fill the wat...

They help me because they always respond any questions and explain me things I do not understand. They also strictly follow the deadlines and I am never late with my assignments. Thank you very much, guys, your hard work is appreciated. I will surely be ordering more.

Oh my Gosh! My life has become sooo much easier after I've come across this website. I am a working student, so sometimes I am too overwhelmed with so many things and I really need a hand with my papers. I am glad I have found a company I can trust. I have confidence in these guys, because they proved to be good quite a few times.

Kirk N.

I never leave reviews for products or services because I am quite particular and picky. Surprisingly enough, EssayPride has managed to satisfy all of my requirements, even though I asked for several alterations to the paper they've sent initially. My assignments are quite complicated and it is essential to possess a certain level of knowledge in order to write a decent paper. These guys have managed, so I give them four stars.

I used this website more than once and every time my experience turned out to be extremely positive. I think their price-quality ratio is very good, because I couldn't find anyone writing better than these guys, who would work for this money. Thank you!

Myung O.

I am a Korean student studying in the US. I would like to thank essaypride staff, especially writer Jeff P., for helping me out so much. My grades are good with all your help and I keep calm about the results of my year.

Boyi Zh.
St. Louis, MO

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
