The oxygen atom in a water molecule A is electrically neutral. B carries a negative electrical charge. C carries a positive elec
Klio2033 [76]

Answer: The oxygen atom in a water molecule carries a negative electrical charge.

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).

In , H_2O , O is a highly electronegative atom attached to a H atom through a covalent bond. Therefore O atom gets partial negative charge and H atoms get partial positive charge.

Neon is an inert gas and has the atomic number of 10. Which of the following correctly depicts its electron configuration? 1s22d
weeeeeb [17]
I think the answer is 1s²2s²2p⁶.  Since neon has an atomic number of 10, we know that it needs to have 10 electrons and since it is in the second row it cannot have any d electrons which makes the first option incorrect.  The second option is incorrect because the 2s⁴ can't exist since s orbitals can only hold 2 electrons.  The fourth option cannot be right because it again neon cannot have d electrons due to it being in the second row.

I hope this helps.  Let me know if anything is unclear.

The color change of an indicator is used to determine ​
lisov135 [29]

Answer:

Whether a solution is acidic or basic can be measured on the pH scale. When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause universal indicator solution to change from green toward red. ... Acidic solutions have a pH below 7 on the pH scale.
