Chemical Reaction : Chemical Reactions

Many factors effect reaction rates, two shown above include temperature and concentration. Concentration affects the rate of reactions because the more concentrated a solution the more likely collisions between particles will be. This is simply because there are more particles present to collide with each other. When the temperature is higher, particles will

The experiment is to observe a variety of chemical reactions and to identify patterns in

- 3058 kJ/mol = [6 (- 393.5) + 3 (- 285.85)] – [X + 0] = - 161 kJ

Purpose: The purpose of this experiment was to observe the many physical and chemical properties of copper as it undergoes a series of chemical reactions. Throughout this process, one would also need to acknowledge that even though the law of conservation of matter/mass suggests that one should expect to recover the same amount of copper as one started with, inevitable sources of error alter the results and produce different outcomes. The possible sources of error that led to a gain or loss in copper are demonstrated in the calculation of percent yield (percent yield= (actual yield/theoretical yield) x 100.

Chemical kinetics involving reaction rates and mechanisms is an essential part of our daily life in the modern world. It helps us understand whether particular reactions are favorable and how to save time or prolong time during each reaction. Experiment demonstrated the how concentration, temperature and presence of a catalyst can change the rate of a reaction. 5 runs of dilution and reaction were made to show the effect of concentration on chemical reactions. A certain run from the previous task was twice duplicated to for a “hot and cold” test for reaction rate. The prior run was again duplicated for a test with

In reference to the collision theory, molecules act as small spheres that collide and bounce off each other, transferring energy among themselves when the collide. In order for a reaction to occur, there must be collisions between molecules. Through experimentation, factors are discovered that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, surface area, the physical state of reactants, and a catalyst. This experiment regarding the factors that affect reaction rate tests the effects of increased concentration and

Introduction: In everything there are things called particles; and sometimes when two particles meet a chemical reaction occurs. Also, with different strategies the chemical reaction can be sped up or slowed down. This is measured with reaction rate which is used to measure the length of a chemical reaction.

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

There are many reaction types that can occur when compounds come together to form different types of products. In chemistry, there are eight different basic types of reactions. The eight basic reactions include: combustion, synthesis, decomposition, precipitation, single-replacement, double-replacement, acid/base, and redox reactions. These reactions are categorized into their reaction type by their differences and similarities. The first type of reaction is combustion.

Chemical reactions are important.Without a freezer coud ylou have nice cold ice cream and without an oven could you have roast chicken or oven fries and the answer is no. Ovens and freezers are very similar as inside heaps of chemicals are reacting to the food so it is either hot or cold.

A chemical reaction is a process in which elements or compounds react with one another to create new or different substances. There are two parts to a reaction. Those two parts are the products and the reactants. The reactants are the chemicals or chemical compounds that are going through the reaction itself. The products are chemical elements or chemical compounds that are produced as a result of the reactant or reactants reacting. There are four key indications that there’s a chemical reaction is taking place. Those four signs include a change in color and/or odor, formation of a precipitate or a gas, the release or absorption of energy (light, heat, electricity), and if the reaction is irreversible. Along with this information, there are ways to predict the products of a reaction.

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

Chemical kinetics studies and determines the rate or speed at which chemical or physical processes occur (Oliver,n.d.)(Jircitano, n.d.). The rate of reaction is the speed at which the reactant in a reaction transforms into products or the change in concentration of a chemical species over the time taken for that change to occur (Oliver,n.d.)(Jircitano, n.d.)(Mack, n.d.)(Blackburn,n.d.). Chemical reactions occur at many different rates and in aqueous or equilibrium systems this rate is dependent on the variables such as the reactivity of reagents, initial concentrations, temperature induced fluctuations and any means of catalysis.
