Hydrogen is one of the most abundant elements in the universe, and it plays a role in many daily life functions.
Naming salts reminder - hydrochloric acid makes chloride salts, sulfuric acid makes sulfate salts and nitric acid makes nitrate salts.
Sodium hydroxide solution reacts with hydrochloric acid solution to produce sodium chloride solution and water. What is meant by a decomposition reaction? Apart from copper compounds, all solutions involved here are colourless and all the salts form colourless crystal if the solution is carefully evaporated to cause crystallisation.
What do you understand by exothermic and endothermic reactions? To electrolyse sulphuric acid, two inert electrodes e. It is also used to produce ethanol and can power electric vehicles. Explain with an example. Explain with equations of these reactions. Respiration, corrosion, rusting and photosynthesis are all examples of redox reactions.
Give one example of chemical reaction. The full equation is: The first part of the salt name is ammonium derived from ammonia with metals or their compounds the metal retains its original namebut the second part of the salt name is always derived from the acid as in NOTE a above.
Hydrogen gas is flammable but it requires oxygen to ignite. When hydrogen burns in oxygen, water is formed and when water is electrolysed, then hydrogen and oxygen are produced.
Name two anti-oxidants which are usually added to fat and oil containing foods to prevent rancidity. Net ionic equation for Iron nitrate and ammonia? Rancidity can be retarded by keeping food in a refrigerator. Oxidation occurs when electrons are lost while reduction takes place when electrons are gained.
Write down the reaction involved. Electrolysis is the breaking up of a compound using electricity. Write the equation for the reaction which takes place.
Also give one use of such a reaction. What is the difference between displacement and double displacement reaction?
Which of the following are exothermic reaction and which are endothermic? What type of chemical reaction is used to extract several metals from there naturally occurring compounds like oxides and chlorides? If a scientist puts a balloon over the flask, it will capture the hydrogen gas and expand.
What are the Ionic equations of electrolysis of dilute sulfuric acid? The dark turquoise-green solid copper II carbonate dissolves in hydrochloric acid to form a greeny-blue solution of copper II chloride and effervescence from the carbon dioxide formed. In exothermic reactions, less energy is used to break bonds in the reactants than to form new bonds in the resulting product.
At the anode oxygen is formed and at the cathode hydrogen. The reaction of zinc and hydrochloric acid is specifically a combustion reaction, which is also called an exothermic reaction.
There is a list of compound formulae and their solubility in section 8.Inorganic Chemistry Writing (Net Ionic) Equations for Various Reactions Write the net ionic equation for the reaction that occurs when an aqueous solution of silver Write the net ionic equation for the reaction of solid magnesium oxide wi th dilute sulphuric acid Answer: MgO(s) + 2H+(aq).
(i) Write correctly balanced equation for the reaction between Iron and dilute sulphuric acid. (ii) Write correctly balanced equations for the reaction of dilute sulphuric acid with each of the following: (a) Copper carbonate (b) Lead nitrate solution (c) Zinc hydroxide.
Iron reacts with dilute sulphuric acid to form ferrous sulphate.
The balanced equation is: Fe +H2SO4 -> FeSO4 + H2 Case 2. Iron reacts with conc. Sulphuric acid to. The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas. This single replacement reaction is a classic example of a metal reacting in an acid to release hydrogen gas.
Oct 11, · Write balanced molecular and net ionic equations for the reactions of? 1)hydrochloric acid with nickel (Express your answer as a balanced chemical equation.
