Answer:
The answer to your question is: B and C.
Explanation:
Neon atomic number = 10
Electron configuration is not : 1s²2s¹2p⁶ .
This electron configuration is for fluor (9 electrons) because is we sum up the electrons ( 2 + 1 + 6) the result is 9.
A)The 3s orbital should be part of the configuration. This is not the right reason.
B)The total number of electrons is incorrect. This correct, the number of electrons is 9 instead of 10.
C)The 2s orbital does not have enough electrons. This option is correct, 2s must have 2 electrons and it only has 1.
D) The 1s orbital does not have enough electrons. This option is incorrect, 1s orbital can have only 2 electrons.
Answer:
The behaviour of gases is described in terms of kinetic theory , which considers the motion of molecules in the gas . The gas link pressure , volume and temperature .
Explanation:
Zero order are reactions in which concentration of reactant has NO effect on RATE OF REACTION.
2. First order are reactions in which concentration of one reactant is proportionate to the RATE OF REACTION.
Exp: That means when you increase the concentration of the one reactant, then the rate of reaction will increase by the same degree of extent.
3. Second order are reactions in which concentration of two reactant has an effect on the RATE OF REACTION.
Formula:
1. Zero order Rate = k
2. First order Rate = k(A)^m
3. Second order Rate = k(A)^m(B)^n
where () represents concentration
and equation is mA + nB -> Product.
A is the answer.
Ice is solid, however, water is liquid. Yet ice still floats which is less dense than water.
Hope this helps!
Density that is determined by a balance between gravity and pressure
