Answer: 1) 
Equilibrium constant is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to their stochiometric coefficients.
![K_{eq}=\frac{[H_2S]^2}{H_2]^2\times [S_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BH_2S%5D%5E2%7D%7BH_2%5D%5E2%5Ctimes%20%5BS_2%5D%7D)
where [] = concentration in Molarity=
Thus ![[H_2S]=\frac{68.5}{1.0}=68.5M](https://tex.z-dn.net/?f=%5BH_2S%5D%3D%5Cfrac%7B68.5%7D%7B1.0%7D%3D68.5M)
![[H_2]=\frac{0.50}{1.0}=0.50M](https://tex.z-dn.net/?f=%5BH_2%5D%3D%5Cfrac%7B0.50%7D%7B1.0%7D%3D0.50M)
![[S_2]=\frac{0.020}{1.0}=0.020M](https://tex.z-dn.net/?f=%5BS_2%5D%3D%5Cfrac%7B0.020%7D%7B1.0%7D%3D0.020M)
![K_{eq}=\frac{[68.5]^2}{0.50]^2\times [0.020]}=938450](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5B68.5%5D%5E2%7D%7B0.50%5D%5E2%5Ctimes%20%5B0.020%5D%7D%3D938450)
As the value of K is greater than 1, the reaction is product favored.
2) 
![K_{eq}=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)
![K_{eq}=\frac{[0.500]^2}{[0.0250]}=10](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5B0.500%5D%5E2%7D%7B%5B0.0250%5D%7D%3D10)
3) 
![K_{eq}=\frac{[NH_3]^2}{[N_2]\times [H_2]^3}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5Ctimes%20%5BH_2%5D%5E3%7D)
4) Reactions which do not continue to completion are called equilibrium reactions as the rate of forward reaction is equal to the rate of backward direction.
Answer:
Benzene will form a solution with hexane. c6h14
Answer:
A chemical reaction produces formaldehyde, with a chemical formula of CH2O. Carbon is in Group 4A, oxygen is in Group 6A, and hydrogen is in Group 1A on the periodic table. In one to two sentences, can you describe the bonds in a molecule of formaldehyde in terms of valence electrons?
Explanation:
Answer:
Carbon Monoxide is a polar covalent bond.
Explanation:
A): The closest orbital to the nucleus, called the 1s orbital, can hold up to two electrons. This orbital is equivalent to the innermost electron shell of the Bohr model of the atom. It is called the 1s orbital because it is spherical around the nucleus. The 1s orbital is always filled before any other orbital.
