Hydrogen chloride

An example of a combination reaction is when hydrogen and chlorine react to form hydrochloric acid: !!!Types and Examples Constructing and balancing chemical reactions from words are essential skills in chemistry. Before we proceed with the lesson, let us remember that when we refer to single…

This is shown in the balanced chemical equation by the products of water and the solid copper chloride. The observation of the liquid turning clear represents the water and seeing the particles represents the precipitate. The yield of copper chloride is 1.49 grams. This demonstrates the transformation of the copper hydroxide being converted into regular copper oxide and with the rest of the mass becoming water. The limiting…

example: Highly pure silicon for computer chips is produced through a displacement reaction. In this reaction, hydrogen reacts with silicon tetrachloride to form hydrogen chloride and release silicon. 4. Double displacement reactions: Double displacement reactions are those in which two compounds exchange ions to form two new compounds. For example: In the reaction of copper sulphate and hydrogen sulphide, copper sulphide and sulphuric acid are…

Ammonia is a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to…

Atomic structure AC1.1 1. Produce a table showing each sub-atomic particle with their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

With this being said, bromine is used in day-to-day operations and can be found everyday products. Bromine can be obtained from the ocean (sea water), and although the sodium chloride is found more often; sodium bromide is found but in smaller quantities. As shown in Figure 2.1 perbromate (BrO4-) is an ion. It carries a molar mass of 143.902 g/mol. Perbromate has 32 valence electrons; bromine carries 7 and oxygen carries 24…

The goal of this experiment was to use chemistry to analyze an unknown compound and through testing its physical and chemical properties determine what unknown compound that was found in a landfill. This would benefit the Environmental Protection Agency because once they know what the substance was they could determine the best way to remove it from the landfill and if there were any potential safety hazards to beware of while handling the substance. This would prevent any accidents that may…

There are five common ways to predict the product of chemical changes. They are synthesis (composition), decomposition, single replacement, double replacement, and combustion. Each can be used for different types of problems based on the equation of experiment presented to you. They can also be found using observations throughout the experiment. You use these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our…

Background research: Redox reactions includes the two reactions called oxidation and reduction. Oxidation is defined as the loss of electrons, loss of hydrogen and gain of oxygen. Reduction, on the other hand, is defined as the gain of electrons, gain of hydrogen and loss of oxygen. Oxidation occurs when there is an increase in oxidation numbers and reduction occurs when there is a decrease in oxidation numbers. Oxidation numbers are values assigned to an atom in a compound which measures the…
