Answer: The formula of the compound formed between rubidium and fluorine is RbF

Explanation:

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Rubidium is the 37th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^1$

This will loose 1 electron to form $Rb^+$ ion

Fluoride is the 9th element of the periodic table having electronic configuration of $1s^22s^22p^5$

This will gain 1 electron to form $F^-$ ion

To form $RbF$ compound, 1 rubidium ion is needed to neutralize the charge on fluoride ion

The formation of the given compounds is shown in the image below.

Which compound would produce an acidic aqueous solution? Which compound would produce an acidic aqueous solution? RbH C2H2 PH3 C

Anvisha [2.4K]

Answer: Option (e) is the correct answer.

Explanation:

A compound that will dissociate in water or an aqueous solution to give hydrogen ions( $H^{+}$ ) is known as an acidic substance.

When RbH is dissolved in aqueous solution then it dissociates as follows.

$RbH \rightarrow Rb^{+} + H^{-}$ .

$C_{2}H_{2}$ is non-polar in nature. So, it will not dissociate into ions when dissolved in an aqueous solution.

$PH_{3}$ will also remain neutral and does not dissociate into ions.

$CaH_{2}$ when dissolved in water then it dissociates as follows.

$CaH_{2} \rightarrow Ca^{2+} + 2H^{-}$

Whereas when HF is dissolved in aqueous solution then the reaction will be as follows.

$HF \rightarrow H^{+} + F^{-}$

Thus, we can conclude that out of the given options HF is the compound which will produce an acidic aqueous solution.

Bad White [126]

Answer:

-1043,8 KJ

Explanation:

Hello!

It is necessary to accommodate the reactions to get the reaction of my interest.

Reaction A reverses what modifies its energy in its sign (+72.6 KJ).

Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).

Reaction C reverses what modifies its energy in its sign (-87.6 KJ).

By sum of the energies I get the energy of the global reaction.
