For the lesson observed the objectives was to explain the trends of the periodic table based on the elements’ valence electrons and atomic numbers. Additionally, students were responsible for applying their previous knowledge in calculating subatomic particles to review the Bohr Models and discus the relationship among families in the periodic table. Students will use the information from today’s lesson to make future judgments on reactivity and bonding created during chemical reactions in the next unit. Lastly, students were to connect the information on elemental properties to previous experiences with their health, commercial products, and everyday life.

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

An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding.

There were 3 objectives for this lab they were demonstrate that mass is conserved in chemical transformations, practice balancing out chemical equations for reactions observed in the lab and practice the skill of recognizing chemical reactions and making detailed observations.

Materials We did several different examples of chemical equilibriums using different stresses and conditions. This includes adding or removing reactants, changing temperature, or adding additional compounds. Our materials included a large variety of chemicals and equipment used to conduct our labs.

This report discusses how varying the mole ratio of the reactants affects the amount of the product that is produced and the amount of the reactants that remain at the end of the chemical reaction. We know that you can’t simply add another atom of nitrogen and take an atom of hydrogen away from ammonia because it would change to another substance. We also know that in a chemical reaction atoms cannot be created or destroyed but can make a new substance. A guiding question was made so they can figure out how to solve/find out what is going on. The atomic theory is connected to this lab because that the atoms in the lab cannot be created of destroyed during a chemical reaction. Meaning that each side the of the equation must include the same number of each type of atom. The relationship between the amounts of any two compounds, in moles, that are involved in a chemical reaction. In this lab we are showing how different ratios of moles of sodium bicarbonate and acetic acid and how the different moles leave and percentage out of the product but still remains in the lab. How this lab works we will combine sodium bicarbonate and acetic acid and we are see the amount of CO2 leftover after the reaction happens. Knowing this.

When dealing with chemical reaction there are equations called chemical equations. Chemical equations give the reactants and products of a chemical reaction. When given just the reactants of an equation, you can predict the products by balancing each side of the equation. The products and reactions are separated by an rnx arrow

In this lab relating to the Law of Conservation of Mass, the mass changed because the gas was released from the chemical reaction. The Law of Conservation of Mass demonstrates that before and after the chemical reaction, the mass of reactants and the mass of products have to be the same.

Problem: How does the electronegativity of 1.25 mol/L of hydrochloric acid, 1.25 mol/L of sulphuric acid, and 1.25 mol/L of nitric acid, affect the rate at which magnesium will react at room temperature(21°C)? Background: A chemical reaction is the rate at which a substance goes through a change and it is transformed into another substance that has different compositions as well as properties.1 The rate at which a chemical reaction occurs depends on many factors, some of which include the concentration of a reactant2, temperature2, collision theory and electronegativity3. Concentration of a reactant effects the rate of reactivity.

When considering the symbolic level of representation used in teaching kinetics, the types of models commonly used by educators can be classified into two categories: (a) balanced chemical equations or (b) mathematical-based equations and graphs. Balanced chemical equations are traditionally used to support student understanding of the overall, complex reaction under study in the experiment or simulation. Balanced chemical equations are also used to support a mechanistic understanding of the step-by-step process of reactants turning becoming products. Here, balanced chemical equations illustrate the creation and consumption of reaction intermediates, as well as providing insight as to how a catalyst interacts with the reacting species at a

Format your data into 6 'panels', that when printed on paper are exactly 9.5 cm square.

Chemical reactions are used in experiments and tests to either see what will happen or to see what

Thermochemistry deals with energy and how it changes. We performed chemical reactions in a calorimeter, which is a device scientists use to determine the amount of heat produced by a process (or change). Processes that absorb energy are endothermic and processes that release energy are exothermic. Endothermic, processes that absorbed energy produced positive results. Where as, exothermic, processes that release energy produced negative results. This experiment also dealt with specific heat. Specific heat is the amount of heat gained or lost when one gram of a substance changes temperature by one degree Celsius. Our experiment this week explored these concepts.

Energy is encountered in many forms, such as mechanical, chemical (food and fuel), electrical, nuclear, heat, and radiant (light). Energy has the ability to bring about change or to do work. Thermodynamics is the study of energy. The field of thermodynamics studies the behavior of energy flow in natural systems. These studies have rendered two laws of thermodynamics.
