Answer:
Hey there!
The volume of the box would be 45(7)(15), or 4725 cm^3.
The density of any object is the mass divided by volume. Thus, the density of the water would be 14/2, or 7 g/cm^3.
Let me know if this helps :)
A hydrocarbon has only hydrogen and carbon in it. the 1st, 3rd and 4th option all include Oxygen so the only hydrocarbon is option 2
At l = 3, ml =+3,+2,+1,0,-1,-2,-3
What are quantum numbers?
- Quantum numbers are used to describe where around a nucleus a particular electron can be found.
- In any given atom, each electron can be described by four quantum numbers.
- These are n,l,m1,ms
- The values that each number can be are based on a set of rules.
What is a magnetic quantum number ?
- It describes the orientation of the orbitals.
- It is represented as ml.
- The value of this quantum number ranges from (-l to +l).
- When l = 2, the value of will be -2, -1, 0, +1, +2.

Answer:
D). Much lower than
Explanation:
When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is <u>Much lower than</u> the concentration of the ketone
because :
Carbon- oxygen bond is more stable(stronger) than Carbon-Carbon Bond
Keto - enol tautomerism is :
Ketone has C=O and enol has C=C
C=O bond energy is 745 kJ/mol
C=C bond energy is 614 kJ/mol
