First, not all chemicals react when mixed. Second, chemicals may not have a change detectable by human senses, such as a change in pH.
When two chemicals bubble upon mixing, it typically indicates a chemical reaction is taking place. The formation of gas bubbles usually suggests a release of gas as a product of the reaction. This observable change is a common indicator of a chemical transformation.
Night sweats can be a sign of cancer because cancer cells can cause the body to produce chemicals that disrupt the body's temperature regulation, leading to excessive sweating during sleep.
No, boiling is not always a sign of a chemical reaction.
Of course! almost any reaction in aqueous soloution is reversable. All reactions go both ways. Temperature, catlysts, pressure affect. The trick is to make the reaction go the way you want it to go so as to produce the desired result. I personally do not know what reaction reguarding vinegar you are referring to. Remember the equals sign on a chemichael reaction goes both ways! JCF
Hazardous chemicals
It is sign of chemical reaction because smell and heat is produced.
This sign doesn't exist.
The () sign in a chemical reaction signifies that a substance is being added or combined with another substance.
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
No, just bad love and sex combinations.
The products of the reaction will have less energy than the reactants
An exothermic reaction is typically indicated by a negative sign in front of the enthalpy change (∆H) in the reaction equation. This negative sign signifies that heat is released to the surroundings during the reaction.
