Data:
Molar Mass of Nickel = 58,7 g/mol
Solving:
58,7 g → 1 mol
y -------→ 2.63 mol
Solving: (They are proportional measures, the rule of three is made (directly proportional)
multiply cross
The noble gas configuration system helps to shorten the total electron configuration by using the symbol for the noble gas that lies before the particular element in the periodic table.
For example:
Na has atomic number 11
Electron configuration of Na: 1s2 2s2 2p6 3s1
Noble gas electron configuration of Na: [Ne] 3s1
Ne has atomic number 10 and lies before Na in the periodic table.
Answer:
4. The rate law expression relates rate and
concentration.
Explanation:
Answer:
51 stars it said i needed 20 characters because my answer was too short
so yeah.
Answer:
The rate of the forward reaction and the rate of the reverse reaction are equal
The concentrations of the reactants and products no longer change.
Explanation:
The equilibrium state is a state of rest or motion of chemical system.
These are some of the condition for dynamic equilibrium of a system:
the systems must be involved in reversible chemical reactions.
the rate of forward reaction is equal to that of the reverse process.
the system offers no resistance to any change in any of the factors.
there is no change in concentration of each of the species in equilibrium with respect to time.
We can see that a system in equilibrium clearly identifies with the chosen options.
