I don't EXACTLY know but hopefully the description below helps you find the answer!

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.

We cooleda water bottle so the volume was lowered to .050 L, then we heated it to 373 K and thevolume increased to .10 L. What was the initial temperature?

Answers

Answer:

[tex]186.5\ \text{K}[/tex]

Explanation:

[tex]V_1[/tex] = Initial volume = 0.05 L

[tex]V_2[/tex] = Final volume = 0.1 L

[tex]T_1[/tex] = Initial temperature

[tex]T_2[/tex] = Final temperature = 373 K

From the ideal gas law we have

[tex]PV=nRT[/tex]

[tex]V\propto T[/tex]

[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\Rightarrow T_1=\dfrac{V_1}{V_2}\times T_2\\\Rightarrow T_1=\dfrac{0.05}{0.1}\times 373\\\Rightarrow T_1=186.5\ \text{K}[/tex]

The intial temperature is [tex]186.5\ \text{K}[/tex].

Answer:

decomposition of water

Explanation:

The reaction will represent the decomposition of water. It usually carried by an electrolytic process in the laboratory.

Water molecule is broken down into its constituent hydrogen gas and oxygen gas components. The breaking down of one compound to give other compounds is decomposition. This is not a replacement reaction. In decomposition, we often start with a single reactant and results in one or more products.
