Answer:
The definition of an absolute reference frame would be that fixed reference frame that every observer would rest at all times in his/her state of motion.
Explanation:
Answer:
A system is in equilibrium when the rate of the forward reaction is equal to the rate of the reverse reaction.
Explanation:
In a system in equilibrium, the rupture and formation of new bonds from the formation and decomposition of substances must have the same reaction rate. Thanks to equal speeds we can say that a system in equilibrium is dynamic and in general every system tends to move spontaneously towards equilibrium. The environment never interferes.
For example.
N2 (g) + 3H2 (g) ---> 2NH3 (g) formation
2NH3 ----> N2 (g) + 3H2 (g) decomposition
N2 (g) + 3H2 (g) <------> 2NH3 (g) In equilibrium

There is 6 non - bonding pairs.
Let me show you one easy method to do this.
o22-, oxygen valence electron = 6 here we have two so total 12, and -2 that means we add electrons so it’s all equal to 14 right.
whenever need to find lone pair, subtract the number you get with the lowest multiple of 8.
here we total 14 valence electron right so lowest multiple of 8 would be 8.
so 14 - 8 = 6 and that is our answer.
Let me know if you have Problem with chemistry.
