Double Replacement
A double replacement reaction.
Synthesis
'Add'. It can also be represented by the 'plus sign' ('+'). The word 'Ad' is short for 'Advertisement'.
It is the general form of a quadratic equation.
Double Replacement
A double replacement reaction.
The reaction represented by 2K + I2 is a combination or synthesis reaction, where potassium (K) and iodine (I2) combine to form potassium iodide (KI).
The reaction represented is a single displacement reaction, where potassium (K) displaces iodine (I2) from potassium iodide (KI) to form potassium iodide and elemental iodine.
The reaction you've provided is a combustion reaction. In this reaction, methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) as products.
Copper plus oxygen react to form copper oxide. This reaction can be represented by the chemical equation: 4Cu + O2 → 2Cu2O.
This is a single displacement reaction, where zinc (Zn) replaces sodium (Na) in sodium chloride (NaCl) to form zinc chloride (ZnCl2) and sodium (Na) metal. The reaction is also known as a displacement or substitution reaction.
This is a single replacement reaction where chlorine (Cl2) displaces bromine in sodium bromide (NaBr) to form sodium chloride (NaCl) and bromine gas (Br2).
Synthesis
The reaction represents a single replacement reaction where the metal displaces the hydrogen in the acid to form a salt and releases hydrogen gas as a byproduct.
The products of neutralization reaction are water and a salt.
This is a chemical reaction known as a single displacement or redox reaction. In this reaction, aluminum (Al) replaces hydrogen (H) in hydrochloric acid (HCl) to form aluminum chloride (AlCl3) and hydrogen gas (H2).
