Single displacement reactions are useful in understanding the patterns of reactivity of elements of the same type. One everyday item that we use that is the result of a single displacement is table salt. When calcium chloride reacts with sodium, the result is sodium chloride and calcium. Sodium chloride is table salt. Show
Why is single replacement reaction important?In the activity series of metals, we can say that Li can replace K in a single-displacement reaction because Li is more reactive than K. It is always important to predict the products of the chemical reaction correctly and make sure that the final chemical equation is balanced. What is a real life example of single replacement reaction? An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H. How is combustion used in everyday life?Combustion in daily life examples are: Burning of Wood or Coal for the household purposes. Burning of Petrol or Diesel for using vehicles like car. Combustion of Natural Gas or LPG to cook. What is the purpose of the Think step?think STEP helps you construct a University Admissions Triangle of Talent™ for reaching your dream school: academics, extracurricular leadership, and your personal story. Build academic and leadership skills for admissions success. Designed for 7th-10th graders at international schools. How combustion is useful? Combustion is another word for burning. When fuels burn in combustion reactions, they release useful thermal energy (heat). Combustion reactions are used to heat our homes, power most cars, and to generate a lot of our electricity. How is combustion used in cooking?The heat released by the combustion of food is used to heat a known mass of water. As the water absorbs energy, the temperature of the water increases. The heat of combustion of a food (enthalpy of combustion of a food) is referred to as the energy content of the food and is provided on the label of packaged food. What are useful chemical reactions?Chemical reactions that are used to make new materials include: Water and carbon dioxide reacting to form glucose and oxygen. The burning of methane to form carbon dioxide and water. The burning of octane to form carbon dioxide and water. The conversion of iron ore to iron. What is chemistry used for in everyday life? Chemistry is a big part of your everyday life. You find chemistry in foods, the air, cleaning chemicals, your emotions, and literally every object you can see or touch. What industry uses combustion?Heating devices for vapour production (steam, etc.), in metallurgy, and in industry generally, utilize the combustion of gases, wood, coal, and liquid fuels. What are some real-life examples of single replacement reactions?Here are some examples of single replacement reactions: zinc + hydrochloric acid —> zinc chloride and hydrogen gas zinc + silver nitrate —> zinc nitrate and silver metal calcium + water —> calcium hydroxide and dihydrogen iron + copper nitrate —> iron nitrate and copper metal bromine + potassium iodide —> potassium bromine and iodine Which is the general form for a single replacement reaction? All single replacement reactions have the general form: A + BC ® B + AC. Here, A is an element and BC is usually an aqueous ionic compound or an acid (consisting of B+ and C- aqueous ions). Element A replaces B in BC, resulting in the formation of a new element B and a new ionic compound or acid, AC. What is a real-life example of a single replacement?zinc+hydrochloric acid —> zinc chloride and hydrogen gas How do you balance a single replacement reaction?You balance the equation for a single replacement reaction the same way as any other equation. You place coefficients in front of the chemical formulas so that the numbers of atoms of the elements are the same on both sides.
Real life examples of single replacement reactions include the exterior of the Statue of Liberty and processes in the steel industry. The reaction takes place between different metals or halogens. A single replacement reaction occurs when an element reacts with a compound, displacing another element in that compound, according to the University of Memphis. The reaction takes place when different types of metals or halogens come into contact with one another, such as zinc dissolving in an acidic solution. In this single replacement reaction, zinc displaces hydrogen from the compound to result in salts and hydrogen gas. Statue of Liberty The Statue of Liberty has an inner iron support and a copper exterior. In time, the statue acquired a verdigris coating, which is the blue-green patina that forms on copper due to atmospheric oxidation. A single replacement reaction that occurs between the verdigris and the iron support transforms the exterior of the statue back to copper. However, the interior iron support oxidizes and becomes rusted. Steel industry Steel is an alloy of iron with carbon. Some manufacturers take the inorganic compound ferric oxide, also known as iron oxide, and cause a single displacement reaction with a type of coal called coke. The coke displaces the iron from the ferric oxide. |
