You didn't show a reaction. The way you would know is by studying/memorizing or looking up the SOLUBILITY RULES.
Changes in color: If the color of the reactants or products changes during the reaction, it is a sign that a chemical reaction has occurred. Formation of a gas: Production of gas bubbles or fizzing indicates a chemical reaction, such as in the reaction between an acid and a carbonate. Changes in temperature: If the reaction absorbs or releases heat, causing a change in temperature in the surroundings, it signals a chemical reaction has taken place.
Observation of a change in the appearance of the metal, such as discoloration or formation of a patina. Production of bubbles or gas, indicating a chemical reaction is occurring. Increase in temperature or release of heat during the reaction.
When excess iron(III) chloride is added to zinc, it can undergo a displacement reaction where the zinc displaces the iron from the iron(III) chloride solution. The products of this reaction would be zinc chloride and iron.
If u add water to lime it will be lime water which is base thus when acid reacts with base then that will be "neutralization reaction". And formation of salt and water will take place. It will be exothermic in nature.
You sweat if thermoregution is taking place
The best way to know when a physical change is taking place is to observe. There will be a visible change in physical changes.

When barium hydroxide reacts with ammonium chloride, the reaction is exothermic, which means it releases heat. This causes the temperature to increase in the surroundings where the reaction is taking place.
A chemical reaction taking place when burning magnesium in air can be indicated by the bright white flame and the formation of magnesium oxide, a white powder that forms on the surface of the magnesium. Heat is also released during this exothermic reaction.
i don't know :P
You can tell a chemical reaction is taking place if there is a change in color, temperature, formation of gas bubbles, or the production of a precipitate. Additionally, if the reactants are transformed into new substances with different properties, a chemical reaction has likely occurred.
I dont know you tell me.
Apparently, the first person who answered this question said ...'its easy find it out yourself' Buh im just gunna tell yuh dah ....i dnt know miiself :)
see i dont know
You can tell that a reaction occurred because you observed the formation of bubbles, which indicates the release of a gas (carbon dioxide) as a product of the reaction between calcium carbonate and hydrochloric acid. The appearance of bubbles is a clear sign of a chemical change taking place.
Anyone who has had a previous unusual reaction to any calcium channel blocker should let his or her physician know before taking the drugs again.
