Any reaction occur.
If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
Oxygen gas must be present for a combustion reaction to occur.
A double replacement reaction may not occur if the possible products are insoluble or if there is no driving force for the reaction to proceed. Additionally, if the reactants do not contain the necessary ions to exchange partners, a double replacement reaction may not occur.
Any reaction occur.
When magnesium is added to hydrochloric acid, a single replacement reaction occurs. The magnesium displaces the hydrogen in the acid to form magnesium chloride and hydrogen gas. The reaction is as follows: Mg + 2HCl → MgCl2 + H2.
Any reaction occur in this case.
Any reaction occur.
Thermodynamically favorable reaction will occur. Also, if the neutral element is higher in the activity series than the charged element, then the reaction will occur.
Any reaction occur.
An endothermic reaction need heat to occur.
A double displacement reaction will not occur if the products formed are insoluble in the solvent, if no reaction occurs between the two compounds, or if the reaction conditions are not suitable for the reaction to proceed.
