Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate

He produced O.‚ by heating mercurv(II) oxide‚ HgO‚ to decompose it into its elements. How many moles of oxygen could Priestley have produced if he had decomposed 517.84 g of mercury oxide? 0. Iron(III) chloride‚ FeCl3‚ can be made by the reaction of iron with chlorine gas. How much iron‚ in grams‚ will be needed to completely react with 58.0 g of Cl2? 194. Sodium

Scrubber systems In short a scrubber system basically removes harmful materials from exhaust gases before they are released into the environment or atmosphere. There are two types of scrubbing methods. There is wet and dry scrubbing. Both systems work in similar ways and have the same end result. That is to change a toxic chemical into something less toxic or non-toxic. Now scrubber systems rely on a chemical reaction with a sorbent (which is a material that sorbs another substance or A substance

THE BENEFITS OF RECYCLING Recycling is one of an important thing to save our life. Recycling means reducing the demands for waste treatment capacity and reducing waste streams. The consumption of non-renewable resources will increase if the less obvious recycling increased. The objectives of recycling are to minimize the resources utilization and emissions of all streams of materials in the production cycle. All the people in the earth should make recycling as their routine in their daily because

further use. A redox reaction involves the transfer of electrons from one element to another‚ whereby the element which loses electrons is the reductant and the element which gains electrons is the oxidant. The rusting of iron(hydrated iron(111) oxide) is an example of corrosion‚ which is under gone everyday. The rusting of iron is an electrochemical process‚. This process involves a number of steps‚ starting with the oxidation of the Iron. Fe(s) → Fe2+(aq) = 2e- Oxygen is then dissolved in the

EXPERIMENT 6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical
