For 1 mole of any substance, there are 6.02214086 × 10^<span>23 particles (atoms, molecules, ions, etc. depending on the substance)
So, for 1 mole of water, there are </span>6.02214086 × 10^23 water particles, and so on
So, in 1 mole of Lithium, there are 6.02214086 × 10^23 Lithium atoms
In reaction 2 moles of SO2 reacts with 5 moles of C...
So for 0.5 mole of SO2 we should have the same ratio ...
C/SO2 = 5/2
Is that clear?
Answer: 1.79 x 10^-5
Explanation: The equilibrium constant of a reaction can be calculated from the quotient of the concentrations of the products over the concentrations of the reactants, with each termed raised to their respective stoichometric coefficients.
For acetic acid, this equilibrium expression is:
![Kc=\frac{[H+] [CH3COO-]}{[CH3COOH]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BH%2B%5D%20%5BCH3COO-%5D%7D%7B%5BCH3COOH%5D%7D)
Replacing the equilibrium concentrations given by the exercise into the expression above, the equilibrium constant, Kc will be obtained and it is found to be equal to 1.79 x 10^-5.
Answer : The correct option for blank 1 is, Forward and Backward direction
.
The correct option for blank 2 is, Reach equilibrium
.
Explanation :
- Reversible reaction : It is a reaction in which two or more reactants react together to give products and these products react with other product to form reactants.
It occurs in both the directions at the same time, forward and backward direction.
- Irreversible reaction : It is a reaction in which reactants react together to give a product but it can not revert back into the reactants.
It occurs in forward direction only.
- Equilibrium reaction : It is a reaction in which the rate of forward reaction is equal to the rate of backward reaction.
- Completion reaction : It is a reaction in which the reactants react together to give products. when the reaction goes to completion theta means all the reactants are used up and you have only products in the reaction.
Answer:
El enlace iónico se da entre dos átomos diferentes (metálico y no. metálico), mientras que el enlace covalente se produce entre dos átomos iguales (no-metálicos). En el enlace covalente hay un compartimiento de electrones, mientras que en el enlace iónico hay una transferencia de electrones
Explanation:
