I think it makes the equation to be more balanced
ironchloride and sulphuric acid
If a reaction produces an insoluble salt, you will observe the formation of a cloudy or precipitate solution in the test tube. This indicates that a chemical reaction has occurred and a solid salt has been formed that is not soluble in the reaction mixture.
You can observe the formation of a precipitate (solid) from two clear solutions or a color change in the reaction mixture. Another indication is the release or absorption of heat or light during the reaction.
No.
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
A double displacement reaction that results in the formation of a precipitate or a gas as a product may not produce a visible product. In such cases, the product may be a colorless or transparent substance, making it difficult to observe any visible changes in the reaction mixture.
The properties mix together with the mixture.
In the enzyme reaction conical tube, you would likely observe a faster rate of reaction and a decrease in substrate concentration over time as the enzyme catalyzes the reaction. In the control reaction conical tube, you would not see significant changes in substrate concentration or reaction rate since there is no enzyme present to facilitate the reaction.
To classify a material as a homogeneous mixture, you typically need to observe at least two sets of properties. These properties should indicate that the components of the mixture are uniformly distributed and that there are no visible differences between different parts of the mixture.
Hamlet asks Horatio to observe Claudius.
As aluminium is a reactive metal, it will oxidise in air to form a hard coating of aluminium oxide which surrounds the metal. To observe the reaction of sulphuric acid and aluminium, this coating must first be specially removed. Effervescence will be observed, and hydrogen gas will be produced. aluminium + sulphuric acid (reacts to form) aluminium sulphate + hydrogen gas
During the elimination reactions of saturated organic compounds double bond (Alkene) or triple bond (Alkyne) is formed to check them add Bromine solution to reaction mixture the decolourization of bromine confirms the elimination reaction
