Answer:
Silicon atoms have 14 protons.
Silicon atoms will react with other atoms in order to gain stability.
Silicon atoms have 14 electrons.
Answer: Increasing the concentration of a reactant or decreasing the concentration of the product.
Explanation: For the equilibrium of the reaction to shift to the left, we must decrease the concentration of a reactant or increase the concentration of the product. This is based on Le Chatelier's principle which describes the effect on the equilibrium of changes in concentration or pressure of a product or a reactant. Adding more products in a system would disturb the equilibrium thus it would cause to reestablish it by shifting the reaction to the left producing the reactants. This would also be the same when you decrease the number of reactants in the system.
Answer:
Chemical equation:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Explanation:
Iron metal react with solid sulfur and produced slid iron(III) sulfide.
The chemical reaction is given below:
Chemical reaction:
S + Fe → Fe₂S₃
Balanced chemical equation:
3S + 2Fe → Fe₂S₃
Balanced chemical equation with physical state:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Ionic equation can not be written because all reactant and products are in solid form.
