Answer:

negative, positive, increase

Explanation:

From the given question,

During the formation of bond, between two atoms with difference between their electronegativity-

The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,

And,

The less electronegative atom, will acquire a partial positive charge.

The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.

And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.

Which of the following substances is most likely to be a liquid at room temperature?

FromTheMoon [43]

The answer is: hydrogen peroxide, H2O2.

H₂O₂(hydrogen peroxide) is pale blue, clear, inorganic liquid.

It is liquid because hydrogen bonds between molecules.

Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.

Because of hydrogen bonds, hydrogen peroxide has higher melting and boiling temperatures than other molecules.

mihalych1998 [28]

Answer:

The answer is C. The partial pressure of hydrogen will be unchanged.

Explanation:

$CO_{(g)} + 2H_{2(g)}$ ⇒ $CH_{3}OH$

Argon with electronic configuration $1s^{2}$ $2s^{2}$ $2p^{6}$ $3s^{2}$ $3p^{6}$ (that is atomic number 18) is an inert gas making it unreactive and it's addition to the reaction has no effect on the partial pressure of either the reactant or production or the state of the system.
