Answer:
Explanation:
I got you....so equilibrium constant is written as products/reactants with raising the products and reactants to appropriate powers based on leading coefficients.
For eg: A+2B------->2C+3D
Keq for this is products/reactions i.e. [(C)^2 (D)^3]/[(A) (B)^2] you see we raised each product or reactant for leading coefficient (the number in balanced equation) power.
In the question above.....
The keq would thus be ![\frac{[H2O] [CO]}{[H2][CO2]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH2O%5D%20%5BCO%5D%7D%7B%5BH2%5D%5BCO2%5D%7D)
therefore answer is B
This has to be more specific..........but the name of the cell is called a galvanic cell and cations react at the cathode. Hope this helps.
Explanation:
the answer can be in liquid, solid and gas
Answer:
12.9 m³ is the new volume
Explanation:
As the temperature keeps on constant, and the moles of the gas remains constant too, if we decrease the pressure, the volume will increase. If the volume is decreased, pressure will be higher.
The relation is this: P₁ . V₁ = P₂ . V₂
1 atm . 0.93m³ = 0.072 atm . V₂
0.93m³ .atm / 0.072 atm = V₂
V₂ = 12.9 m³
In conclusion and as we said, pressure has highly decreased so volume has highly increased.
Answer:
The ancient Greeks were the first to use the word atom,which means indivisible,to describe the smallest particle of any substance. Its actual existence was not established until yhe nineteenth century when John Dalton, an English chemist,put forward a theory to describe the nature of the atom.The atom is now considered to be the basic unit of simple substances or elements.An atom is the smallest particle of an element which can take part in a chemical reaction or an atom is the smallest part of an element that can ever exist and still possess the chemical properties of that element.
