Explanation:
Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.
While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.
As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
Answer:
Explanation:
Some data in the problem are missing.
Missing values:
Radius of the cylinder: 13 cm
Height of the cylinder: 4 cm
The volume of a cylinder is given by
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem, we have:
r = 13 cm (radius)
h = 4 cm (height)
Therefore, the volume of the cylinder is:
Answer:
I don't know but you got this!!
Answer:
Enhanced Green house effect
Explanation:
The paradox describes the inconsistency between the faint young Sun and the temperate climate on the early Earth. Despite low radiation by the sun of the early year, the Earth still maintained a temperate climate.
This paradox can be resolved by instigating changes in the atmospheric concentrations of greenhouse gases like ammonia (NH3), CH4, or CO2. This is referred to as enhanced green house effect.
