matter can enter from the surroundings, but cannot escape to the surroundings.
matter is not allowed to enter from or escape to the surroundings.
matter cannot move at all.
matter can enter from or escape to the surroundings.
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
A chemical reaction is the process in which two or more substances interact to form new substances with different chemical properties. This process involves breaking and forming chemical bonds.
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.
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
Bubbling present during a chemical reaction is evidence of a gas being produced. The formation of gas bubbles indicates that a chemical change is taking place, often as a result of a reaction between two or more substances.
When a chemical reaction takes place in an open system, it can exchange both matter and energy with its surroundings. This means that reactants or products can enter or leave the system, affecting the overall reaction. Consequently, the reaction may not proceed as predicted due to these exchanges.
the requiredactivation energy is the basic factor for a reaction to start.
If heat is produced by a chemical system, it means that an exothermic reaction is taking place. In an exothermic reaction, heat is released to the surroundings as a byproduct of the reaction. This can result in an increase in temperature of the system.
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
A chemical reaction is; when there is a chemical change taking place from energy or shifting of molecular structure.
chemical reaction takes place in rancidity
The change in color indicates that a chemical reaction has taken place.
Since argon is a noble gas, I wouldn't expect much to happen; specifically, I wouldn't expect any chemical reaction.
It refers to the energy changes that take place during a chemical reaction.
This chemical reaction is called photosynthesis.
a chemical reaction..
The ending materials in a chemical reaction are called products. These are the substances that are formed as a result of the chemical reaction taking place.
