Modern Chemistry Chapter 4 Review Answers Arrangement Of Electrons In Atoms
Chapter 4 Review, pages — advertisement Chapter 4 Review, pages — Knowledge 1. If a substance changes colour, a chemical change might have occurred. A catalyst speeds the rate of a chemical reaction without being used up. Two simple reactants combine to form a more complex product in a synthesis reaction. Calcium carbonate CaCO3 forms calcium oxide and carbon dioxide gas when heated. True We can use the activity series to determine whether a displacement reaction will occur. Mercury is the only metal that is liquid at room temperature. Four clues that may indicate that a chemical reaction has taken place are an unexpected change in colour, the release or absorption of energy, the production of a gas, and the formation of a precipitate. A catalyst is a substance that makes a reaction occur faster without being used up in the reaction.

In a balanced chemical equation, the total number of atoms of each type in the reactants is the same as in the products. In a chemical equation, coefficients are multipliers that appear before a chemical formula. They indicate how many units of each substance are present. Coefficients can be changed to balance a chemical equation. Subscripts are numbers written below and to the right of a chemical symbol. They indicate how many atoms or ions of that element are present in one molecule or formula unit of that substance. Subscripts describe the composition of a substance and cannot be changed without describing a different substance.

This change is a synthesis reaction because two simpler reactants, carbon dioxide and water, combined to form a more complex product, carbonic acid. Decomposition reactions generally require energy, such as electricity or heat, to proceed. During a synthesis reaction of water, hydrogen and oxygen gases are combined to form water. During a decomposition reaction of water, water is broken down into hydrogen gas and oxygen gas. The reactants of one reaction are the products of the other. Therefore, the synthesis and decomposition of water are opposite reactions. Chapter 4: The Effects of Chemical Reactions Unlike burning garbage, gasification involves heating waste to a temperature so high that the molecules of the garbage decompose into simpler substances.

Plasma gasification results in a mixture of mostly hydrogen and carbon monoxide called syngas. Syngas can be burned to generate electricity that could not only power the gasification plant, but also produce excess that can be sold or used to make industrial chemicals. Three concerns about the gasification of landfill garbage are that gasification may release harmful emissions into the air, it may undermine recycling efforts, and it may pose risks that are not yet identified because it is a new technology in Ontario. The activity series of metals is a ranking of metals according to their reactivity.

The most reactive metals are at the top of the list and the least reactive metals are at the bottom. A metal in the activity series will displace any other metal below it from a solution of a compound. Generally, the least reactive metal is left as an element. Displacement is unlikely to occur between two metals that are close together on the list. The farther apart the two metal are, the more likely a displacement reaction will occur. Fluorine is at the top of the halogen activity series. That indicates that fluorine displaces all other halogens from compounds. Mercury is different from other metals because it is one of the few metals that are found in nature as pure elements, and it is the only metal that is liquid at room temperature.

That is, one element A displaces another element B from a compound BC. That is, two elements A and C displace each other from their compounds. The precipitate that results from a precipitation reaction is in solid state. The symbol aq means aqueous or in water. In a chemical equation, it indicates that the substance is dissolved in water. Understanding Count the number of atoms of each type on either side of the arrow. NaClO3 on the left must be multiplied by 2 and O2 on the right must be multiplied by 3 to balance the oxygen atoms.

H2O on the right must be multiplied by 2 to balance the oxygen atoms, and CO2 must then be multiplied by 4 to balance the carbon atoms. H2O on the left must be multiplied by 2 to balance the hydrogen atoms, and thus the oxygen atoms. Count the number of atoms and ions of each type on either side of the arrow. Count the number of ions of each type on either side of the arrow. Step 1. CO2 and H2O on the right must be multiplied by 6 to balance the carbon and hydrogen atoms. Then multiply O2 on the left by 6 to balance the oxygen atoms. For example, heating water until it boils produces a gas, but there is no new substance formed; shining light on a substance allows it to change colour, but no new substance is formed; rubbing a substance releases energy, but no new substance is formed; drying a salt solution forms a precipitate of salt, but no new substance is formed.

Therefore, a displacement reaction will occur. Write the chemical formulas of the reactants and the atoms and ions involved in the reaction. Identify which is higher on the activity series, the metal element or hydrogen. Al is higher than H. Step 3. Determine the chemical formula of the new compound AC. The remaining element is displaced. Write the balanced chemical equation for the reaction. Identify which is higher on the activity series, the metal element or copper. Zn is higher than Cu. Identify which is higher on the activity series, the metal element or potassium. K is higher than Au. Therefore, no reaction occurs. The ions may become attached to snowflakes and fall to the ice surface, thus being trapped in the ice and snow.

Write the chemical formulas of the reactants. Separate the reactants into their ions. Combine cations and anions to form new compounds. Check for low solubility. CdS is slightly soluble, while H2SO4 is very soluble. Therefore, CdS should precipitate. Ni OH 2 is slightly soluble, while NaCl is very soluble. Therefore, the precipitate is Ni OH 2. Li on the left must be multiplied by 2 to balance the lithium atoms or ions. PbI is slightly soluble, while NaNO3 is very soluble. Therefore, PbI2 should precipitate. That is, a new substance is formed, an evidence of a chemical reaction. Analysis and Application Sample answer: Measure the mass of zinc metal used. Then measure the total mass of the reactants, including the unknown metal, before the reaction. When the reaction is complete, measure the total mass of the final solution. The difference in mass should equal the mass of hydrogen gas that has been given off.

McGlone, Christopher / Chapter 4: Applications Of Derivatives
If the difference is greater than the expected loss in mass due to the release of hydrogen, the unknown metal must have also reacted to produce more hydrogen. The unknown metal is not a catalyst in this reaction since a catalyst should not be used up during a reaction. Answers may vary. Sample answer: Measure the total mass of the reactants before the reaction. When the reaction is complete, measure the total mass of the products.
