When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.

<h3>What is the clolur of flame?</h3>

When a burner is properly adjusted the flame should have an outer violet oxidizing flame and an inner blue reducing flame. The temperature of blue colour is 15000 degree Celsius whereas the cool region outside the blue has 3000C temperature.

So we can conclude that When a bunsen burner is properly adjusted, the flame look like outer violet and inner blue colour.

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

Determine the number of valence electrons for magnesium

12345 [234]

Answer:

Magnesium has 2 valence electrons.

Explanation:

The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.
