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.

40. Write a balanced equation and a net ionic equation for combining AgNO3(aq) and Na2CO3(aq)
Kay [80]

we are given the the two reactants: AgNO3 and Na2CO3 and is asked to write a balanced equation and a net ionic equation for the reaction of the two. This is a double-replacement reaction:
2AgNO3 (aq)+ Na2CO3 (aq)= Ag2CO3 + 2NaNo3 (aq)
2 Ag + + 2 N03- + 2Na+ + CO32- = Ag2CO3 + 2 Na+ 2NO3-
cancelling the spectator ions, 2Ag + + CO32- = Ag2CO3
