Given the reaction fe s - fes energy which is true It is exothermic The potentialenergyof the reactantis the same as the product The potentialenergyofthereactcantislowerthanthe product endothermic?
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
Combination reaction of zinc metal plus sulfur solid?
The combination reaction of zinc metal plus sulfur solid produces zinc sulfide. This reaction occurs when zinc atoms react with sulfur atoms to form a compound. The balanced chemical equation for this reaction is: Zn (s) + S (s) → ZnS (s)
What is the correct cell notation for the redox reaction 3Pb2 plus aq plus 2Cr s 3Pb s plus 2Cr3 plus aq?
The cell notation for the given redox reaction is: Pb₂⁺(aq) | Pb(s) || Cr(s) | Cr³⁺(aq)
What is the products of the reaction CaOs H2Ol CaOH2s?
The reaction is: CaO(s) + H2O(l)--- --> Ca(OH)2(s) Ca(OH)2(s) is the product (at the right side of the reaction equation).
Give the following product what combination reaction and balance 1. Ca plus SO3 2. SbCl3 plus Cl2 3. N2 plus H2 4. S plus O2?
Ca + SO3 → CaSO4 2SbCl3 + 3Cl2 → 2SbCl5 N2 + 3H2 → 2NH3 S + O2 → SO2
What is the generic format of a chemical reaction?
Generic format is Reactant ( plus reactant(s)) = Product + (Product(s))
A substance formed in chemical reaction is a?
Anew substance that is formed is a product in a chemical reaction
What is created after chemical reaction?
product(s)
What is the oxidation half-reaction for Mg s plus ZnCl2 aq --- MgCl2 aq plus Zn s?
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
What are the spectator ions in Mg(s) plus Zn2 plus plus 2NO3- Mg2 plus plus 2NO3- plus Zn(s)?
The spectator ions are NO3- in this reaction. They are present on both sides of the equation before and after the reaction takes place, so they do not participate in the reaction and can be considered spectators.
Given the reaction fe s - fes energy which is true It is exothermic The potentialenergyof the reactantis the same as the product The potentialenergyofthereactcantislowerthanthe product endothermic?
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.

CaCO3 (s) → CaO (s) + CO2 (g) (calcination reaction) Ca(OH)2 (s) → CaO (s) + H2O (g) (dehydration reaction)
Combination reaction of zinc metal plus sulfur solid?
The combination reaction of zinc metal plus sulfur solid produces zinc sulfide. This reaction occurs when zinc atoms react with sulfur atoms to form a compound. The balanced chemical equation for this reaction is: Zn (s) + S (s) → ZnS (s)
What type of reaction is Na plus Cl --NaCl?
The reaction between sodium (Na) and chlorine (Cl) to form sodium chloride (NaCl) is a chemical reaction known as a synthesis or combination reaction. In this reaction, the sodium and chlorine atoms combine to form a single compound, sodium chloride.
What is the correct cell notation for the redox reaction 3Pb2 plus aq plus 2Cr s 3Pb s plus 2Cr3 plus aq?
The cell notation for the given redox reaction is: Pb₂⁺(aq) | Pb(s) || Cr(s) | Cr³⁺(aq)
What is the products of the reaction CaOs H2Ol CaOH2s?
The reaction is: CaO(s) + H2O(l)--- --> Ca(OH)2(s) Ca(OH)2(s) is the product (at the right side of the reaction equation).
