B because inner core has metal and it’s solid
Answer:
So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.
Answer:
CH3CH=NH2+>CH3CH2NH3+
Explanation:
If we look at the both species under review, we will realize that they are both amines hence they possess the polar N-H bond.
Electrons are ordinarily attracted towards the nitrogen atom hence making both compounds acidic. It is worthy of note that certain features of a compound may make it more acidic than another of close structural proximity. 'More acidic' simply means that the proton is more easily lost.
CH3CH=NH2+ contains an sp2 hybridized carbon atom which is highly electronegative and further withdraws electron density from the N-H bond thereby leading to a greater acidity of CH3CH=NH2+ compared to CH3CH2NH3+
A. The cup will sink
Additionally, the water level will rise.
<span>The attraction between the shared electrons
and the nuclei that holds the molecules together in the second energy level of
phosphorus atom is a covalent bond. Electrons are kept in the orbit around the
nucleus by the electromagnetic force and the protons in the nucleus are held in
place by the strong nuclear force, which overcomes the electromagnetic
repulsion.</span>
