Q7.The balanced chemical equation for the rusting of iron is: 4Fe (s) + 3O2(g) → 2Fe2O3(s) How many atoms of each of Fe and O are there each on the reactants side and the products side? 4 Fe and 3 O2on the reactants side and 2 Fe and 1 O3on the products side. ...
List of Chemical Reactions - Get the complete list of all the important chemical reactions like Electrolysis, Rusting of Iron along with their representation and balanced chemical equations.
When an iron object is left in damp air (or water) for a considerable time, it gets covered with a red-brown flaky substance called rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to ...
Painting of iron articles cuts off the contact between the iron surface and air/moisture, thus preventing it from rusting. Question: Write the word equation and the chemical equation of the reaction between sodium and chlorine to give sodium chloride. Solution: Sodium + Chlorine → Sodium ...
3. The overall reaction for the corrosion (rusting) of iron by oxygen is 4 Fe(s) + 3 O2(g) ⇌ 2 Fe2O3(s) Using the following data, calculate the equilibrium constant for this reaction at 25°C given R = 8.314 J mol-1K-1. ...
Acidity in the oil is detrimental as it eventually leads to attack of the metal parts in the form of rusting or corrosion. Parts made of the yellow metals, copper, brass and bronze are especially susceptible to this type of attack. Increasing oil viscosity adversely effects the efficiency of ...
A chemical equation is a mathematical statement which symbolizes the product formation from reactants while stating certain conditions for which how the reaction has been conducted. Reactants are placed on the left side of the equation while products are placed on the right side of the equation ...
together by chemical bonds that hold the chemicals together. plants use solar energy to put the hydrogen, the carbon and the oxygen atoms as a whole in the form of sugar. thus, by the process of photosynthesis chemical energy is stored in plants. q12. why is rusting of iron a chemical ...
