No it cannot. While in theory it appears that Copper and Iron could just switch places, this can not actually take place. Iron has a higher 'reactivity' than Copper does, so in a sense; the Iron holds on too tight to the Chlorine ions for the Copper ions to switch and take its place.
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.
A double arrow in a chemical equation represents a reversible reaction, meaning that the reaction can occur in both the forward and reverse directions. It signifies that the reaction can reach equilibrium where the rate of the forward reaction equals the rate of the reverse reaction.
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.
Any reaction occur.
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and copper (Cu) is: 2HCl + Cu -> CuCl2 + H2 This equation shows that two moles of hydrochloric acid react with one mole of copper to form one mole of copper(II) chloride and one mole of hydrogen gas.
The mass of products equals the mass of reactants.
A gas H2S evolves.
Any reaction occur in this case.
Any reaction occur.
No, the reaction Br2 + NaCl → NaBr + Cl2 does not occur. The correct reaction between Br2 and NaCl is 2NaBr + Cl2.
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.
