balanced chemical equation of photosynthesis class 10

No, double displacement reaction takes place when there is a formation of a slightly soluble salt. Question 13. Predict the new compound formed which imparts a blue-green colour to the solution. Answer: (b) Unbalanced Chemical Equation: If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in the product, then the chemical equation is called Unbalanced Chemical Equation. Photosynthesis: It is the process by which green plants manufacture food by using carbon dioxide and water in the presence of sunlight. Question 12. When quick lime (CaO) is added to water, it releases energy. Basic raw materials for photosynthesis (d) Hydrogen (H2). Answer: C (s) + O2(g) → CO2(g) (a) Physical change 1 Answer +1 vote . The microbes can grow in the plucked grapes and under anaerobic conditions these can be fermented. A general displacement reaction can be represented by using a chemical equation as follows : Answer: Corrosion: The process of slow conversion of metals into their undesirable compounds due to their reaction with oxygen, water, acids, gases etc. Combustion of Liquified Petroleum Gas (LPG) is a chemical change because, after its combustion, a new substance is formed and cannot be turned back into LPG. Magnesium + Oxygen → Magnesium Oxide, When carbon is burnt in oxygen (air), carbon dioxide is formed. (b) Magnesium oxide is an oxide of a metal, so, it is basic in nature. Why should a magnesium ribbon be cleaned before burning in air? When the solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride. Chemical Equation Learning Goals. Precipitation Reaction: The reaction in which precipitate is formed by the mixing of the aqueous solution of two salts is called Precipitation Reaction. FeSO4(aq) + 2NaOH (aq) → Fe(OH)2(s) + Na2SO4(aq). Photographic paper has a coat of silver chloride, which turns into grey when exposed to sunlight. 2Mg(s) + O2(g) \(\underrightarrow { \triangle }\) 2MgO(s) Chemical Reaction: During chemical reactions, the chemical composition of substances changes or new substances are formed. Iron nails become brownish in colour and the blue colour of copper sulphate solution fades. What is the role of a catalyst in a chemical reaction ? Answer: Chemical Equation Of Photosynthesis For Class 7 Differences Between Cellular Respiration And Photosynthesis. To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products. (iv) When lead is treated with hydrochloric acid, bubbles of hydrogen gas are evolved. (i) Following are the two observations : (i) Pb3O4 (c) is exothermic as heat is released in these changes. It happens because silver chloride is colourless while silver is a grey metal. Example: The burning of magnesium in the air to form magnesium oxide is an example of a chemical reaction. Aqueous solution is written by symbol (aq). When magnesium is burnt in the air (oxygen), magnesium oxide is formed. Reaction with dilute HNO, is different as compared to other acids because nitric acid is an oxidising agent and it oxidises H2 gas evolved to H2O. (i) State the two observations made in the experiment. (d) Dissolution of ammonium chloride in water Why is hydrogen peroxide kept in coloured bottles ? ‘Al’ is extra reactive than Mn as ‘Al’ displaces Mn from its oxide. (b) Dilution of sulphuric acid Answer: Mg + 2HCl → MgCl2 + H2 Potassium chlorate (KClO3) on heating forms potassium chloride and oxygen. Question 1. What is wrong with the following equation?
