Answer:
E = 1.602v
Explanation:
Use the Nernst Equation => E(non-std) = E⁰(std) – (0.0592/n)logQc …
Zn⁰(s) => Zn⁺²(aq) + 2 eˉ
2Ag⁺(aq) + 2eˉ=> 2Ag⁰(s)
_____________________________
Zn⁰(s) + 2Ag⁺(aq) => Zn⁺²(aq) + 2Ag(s)
Given E⁰ = 1.562v
Qc = [Zn⁺²(aq)]/[Ag⁺]² = (1 x 10ˉ³)/(0.150)² = 0.044
E = E⁰ -(0.0592/n)logQc = 1.562v – (0.0592/2)log(0.044) = 1.602v
Answer:
carbon dioxide
Explanation:
carbon dioxide is the primary greenhouse gas produced by burning fossil fuels like coal and oil
Answer:
Compounds are pure substance consisting of two or more different atoms
Answer:
A. a poisonous gas is one of the reactants
Explanation:
Chlorine gas is a poisonous and very toxic gas. Chlorine is a moderately reactive halogen. It is a greenish-yellow gas with choking and irritating smell. The gas is very poisonous. Proper care must be taken when working with this gas.
This is why chlorine gas are harmful in production of fireworks.
I think you were doing it right. Just find something in your kitchen and google the chemical formula. And from that you can see the elements in it. For example:
Salt, NaCl, Sodium and Chlorine.
Baking Soda, NaHCO3, Sodium, Hydrogen, Carbon and Oxygen.
Vinegar, CH3COOH, Carbon, Hydrogen and Oxygen
