Zn (s) + 2HCl (aq) → H2 (g) + ZnCl2 (s)
This is a sign of a chemical reaction.
An example of an oxidation reaction is the reaction between magnesium and oxygen to form magnesium oxide: 2Mg + O2 -> 2MgO. In this reaction, magnesium loses electrons to form magnesium ions, Mg²⁺, thereby undergoing oxidation.
When a chemical change occurs, there are two types of ways heat can be involved. In an endothermic reaction, more heat enters the reaction than leaves. In an exothermic reaction, more heat leaves the reaction than enters.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Catalysis is the use of a catalyst in a reaction.Certain substances, called catalysts, can increase the rate of a reaction without being consumed by it.An example is the decomposition of H2O2: 2222(aq)22Catalysts can be described as being homogeneousor heterogeneous.Homogeneous: reaction takes place within a single phase, as in the example above with the H2O2.Heterogeneous: reaction involves two different phases, as in the example that follows. 2N2O ----> 2N2 + O2 - this reaction is usually slow, but if the reactants are bought into contact with a metal such as gold, the reaction speeds up considerably.A catalyst lowers the activation energy required for the reaction. Let me know if this helped or if there is a certain thing that you need me to cover about it.
This is a sign of a chemical reaction.
Example : Action: I poured water on the campfire. Reaction: Fire was extinguished. Action=cause Reaction=what happens because of it
brain and the spinal cord will reaction
no
It could be an allergic reaction.
could you please give me examples of your work
There are various things that you could give a sailor for his birthday. For example, you could give something that is nautical themed.
A neutralization reaction is a chemical reaction between an acid and a base that results in the formation of water and a salt. One example is the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) to form water (H2O) and sodium chloride (NaCl) salt.
It could if you have an allergic reaction to chocolate, and a possibility of an allergic reaction to chocolate would be developing acne. No
amex
No. (:
Could you give an example?
