Copper Reactions Rodney Jay C. Ridao Florencio Louis Pascual Relao De La Salle University- Dasmariñas Dasmariñas Cavite Philippines ABSTRACT The Copper Reactions experiment was demonstrate by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory

What are some of the potential difficulties in approaching strategic planning from a balanced perspective? Isn’t financial performance still the most important perspective to take in planning? Explain. Traditional financial measures – ROI‚ net profit‚ sales growth‚ and market share – fail to capture the true picture of a firm’s value propositions because they focus on the past. They tell the story of what has happened to the organization. They explain the results of past transactions and disregard

A balanced budget will lead to a stronger economy and more jobs. Our government should try to maintain the value of dollar in the market. If the value of dollar appreciates‚ people will trust US market. This will motivate companies to invest and put more money into growth it will be longer lasting. More jobs will be created. If the value of dollar depreciates then it will lead to unemployment. People will not be able to pay for gas and food and the price will inflate more. Now the goal of our govt

Organic food is defined as produce (animal and plant) that is grown without the aid of any chemicals or pesticides‚ this means the animals are fed organic feed and the plants are grown in a very different way to most foods we see at the supermarket. Many people purchase organic food because they think that the nutritional benefits will make up for the extra money that you spend. Lots of people say that the manufacturers of organic food lie to us when selling these products‚ they say that there aren’t

element through a number of chemical reactions including redox‚ metathesis‚ decomposition‚ and single replacement reactions‚ the cycle will be complete once solid copper is recovered. Attempting to create a diagram of the ecological cycle of copper must require knowledge about copper’s chemical cycle first‚ which may then allow for the development of possible solutions to copper pollution.

Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to
