Which of the following statements is correct? In a polar covalent bond, on atom is more electronegative than another and has a stronger hold on the shared electrons.
Atoms bonded ionically have equal electronegativities.
Ο Ο
Non-polar covalent bonds is a common bonding pattern for the noble gases.
Atoms to the right of the periodic chart typically have lower electronegativities than those on the left of the chart.
Chemical bonding involves the sharing of neutrons.

anti-human il13 stable cell line (lebrikizumab) can be provided from creative biolabs.

explanation:

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
