The answer is the telephase.<span />
Answer:
One valence electrons and are the most reactive.
Explanation:they are the alkali metals.
Answer:
NO = 0.0265 mol
Br₂ = 0.0133 mol
NOBr = 0.0389 mol
Explanation:
Let's consider the following reaction.
2 NO(g) + Br₂(g) ⇄ 2 NOBr(g)
We can find the composition at equilibrium using an ICE chart. Let x be an unknow amount.
2 NO(g) + Br₂(g) ⇄ 2 NOBr(g)
I 0.0655 0.0328 0
C -2x -x +2x
E 0.0655 - 2x 0.0328 - x 2x
At equilibrium, the mixture contains 0.0389 mol NOBr. Then,
0.0389 mol = 2x
x = 0.0195 mol
The composition of the equilibrium mixture is:
NO = 0.0655 - 2x = 0.0265 mol
Br₂ = 0.0328 - x = 0.0133 mol
NOBr = 0.0389 mol
Answer:
Number of moles = 0.05 mol
Explanation:
Given data:
Mass of Pb = 10.5 g
Number of moles of Pb = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of Pb is 207.2 g/mol.
Now we will put the values in formula.
Number of moles = 10.5 g/207.2 g/mol
Number of moles = 0.05 mol
We can achieve equilibrium state, when the concentration of product and reactants are equal to each other.
<h3>Describe this system when it reaches phase equilibrium?</h3>
In this type of system, when the same amount of liquid water is converted into gaseous form of water and the gaseous form of water into liquid form of water. This phase is known as equilibrium phase or state because same amount of reactants and products are produced .
So we can conclude that we can achieve equilibrium state, when the concentration of product and reactants are equal to each other.
