When ammonium nitrate is added to a suspension of magnesium hydroxide in water, the Mg(OH)2 dissolves. Write a net ionic equatio
Viefleur [7K]

Answer:

Net ionic: Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O

Explanation:

OH^{-} in Mg(OH)_{2} reacts with NH_{4}^{+} to form NH_{3} and H_{2}O.

Due to this acid-base reaction, Mg(OH)_{2} become soluble whenever NH_{4}NO_{3} is added to suspension of Mg(OH)_{2}.

In this reaction, NH_{4}NO_{3} acts as an acid and Mg(OH)_{2} acts as a base.

Molecular equation: Mg(OH)_{2}+2NH_{4}NO_{3}\rightarrow Mg(NO_{3})_{2}+2NH_{3}+2H_{2}O

Total ionic: Mg(OH)_{2}+2NH_{4}^{+}+2NO_{3}^{-}\rightarrow Mg^{2+}+2NO_{3}^{-}+2NH_{3}+2H_{2}O

Net ionic: Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O

Isopropanol major species present when dissolved in water
timofeeve [1]

Answer : Isopropanol molecules ( C₃H₈O) are the major species present when dissolved in water.

Explanation :

Compounds are of 2 types.

1) Ionic compounds : These are formed by the transfer of electrons from a metal to a non metal.

When ionic compounds are dissolved in water, they get separated into ions.

Therefore the major species present in case of an ionic compound are ions.

2) Molecular (Covalent) compounds: These are formed by sharing of electrons among 2 or more non metals.

Covalent compounds are further categorized as

a) Polar covalent : Polar covalent compounds partially dissociate to form ions.

Therefore the major species in case of polar covalent compounds are the undissociated molecules and ions.

b) Non polar covalent : Non polar covalent compounds are unable to dissociate and they remain in molecular form when dissolved. So the major species in case of a non polar compound are undissociated molecules only.

Isopropanol is a non polar covalent compound. As discussed above it will have undissociated isopropanol molecules as major species.

Hence Isopropanol molecules ( C₃H₈O) are the major species present when dissolved in water.

Yeah, I think you just need to get permission from the school itself. I have seen people do it before at my old school. I would ask your friend and see if they could talk to someone about it.

Which Lewis electron-dot diagram is correct for CO2?
Effectus [21]

Answer:

see explanation

Explanation:

The Lewis structure of a substance is otherwise known as its dot electron structure. It gives an immediate picture of the bonding and number of electron pairs in the molecule. The diagram shows only the valence electrons on each of the bonding atoms in the molecule and how they combine to form the molecule under consideration.

The correct Lewis structure for CO2  is shown in the image attached. CO2 has 16 valence electrons. This can be verified by counting the number of dots in the image attached.
