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

A property is a characteristic of a substance that can be observed and does not change the identity of the substance. T/F
Murljashka [212]
The correct answer is false. The statement given does not describe a property in general. However, it speaks of a specific type of property which is the physical property.  This property is the one that does not change the identity of a substance. A property can also be a chemical property where the identity of a substance is changed.

A molecule has sp2 hybridization with 1 lone pair.... The electron pair geometry of this molecule is: ... The geometry of this m
MrRa [10]

Answer:

The electron pair geometry is Trigonal planar

Molecular geometry - Bent

Approximate bond angle - <120°

Explanation:

The valence shell electron pair repulsion theory enables us to predict the shapes of molecules based on the number of electron pairs present on the valence shell of the central atom and based on the hybridization state of the central atom.

sp2 hybridization corresponds to trigonal planar geometry. Let us recall that the presence of lone pairs causes a deviation of the molecular geometry from the expected geometry based on the number of electron pairs.

Hence, owing to one lone pair present, the observed molecular geometry is bent.

Which of these solutions are basic at 25 °C? Solution A: [OH−]=3.13×10−7 M Solution C: [H3O+]=0.000747 M Solution B: [H3O+
solong [7]

Answer:

Are basic:

[OH⁻] = 3.13x10⁻⁷M and [H₃O⁺] = 9.55x10⁻⁹M

Explanation:

A solution is basic when pH = - log [H₃O⁺] is higher than 7.

It is possible to convert [OH⁻] to [H₃O⁺] using:

[H₃O⁺] = 1x10⁻¹⁴ / [OH⁻]

a. [OH⁻] = 3.13x10⁻⁷M

[H₃O⁺] = 1x10⁻¹⁴ / [3.13x10⁻⁷M]

[H₃O⁺] = 3.19x10⁻⁸M

pH = - log [H₃O⁺] = 7.50

[OH⁻] = 3.13x10⁻⁷M is basic

b. pH = -log [H₃O⁺] = - log 0.000747M = 3.13.

This solution is not basic

c. [H₃O⁺] = 9.55x10⁻⁹M

pH = 8.02

This solution is also basic.
