Answer: Decomposition reaction

Explanation: Decomposition is a type of chemical reaction in which a single reactant gives two or more than two products.

Decomposition requires energy for breaking of bonds and thus is always a endothermic process. It may occur in the presence of heat, light or electricity.

$2KClO_3\rightarrow 2KCl+3O_2$

The following reaction is a DECOMPOSITION reaction evident by the fact that instead of multiple reactants reacting to produce products, a single compound breaks up (decompose) to form multiple products.

The product that is formed is shown in the figure , Option A is the correct answer , and the highlighted carbons shown corresponds to the carbons from diethyl malonate.

<h3>What is a Chemical Reaction ?</h3>

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Substances are either chemical elements or compounds.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Chemical reactions are an integral part of technology, of culture, and indeed of life itself.

Calculate the oxidation number of the iodine (I) in each compound: HIO4 = I2 = NaI = HIO3 =

Alisiya [41]

1) in periodic acid (HIO₄), iodine has oxidation number +7, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 4 · (-2) = 0.
x = +7.

2) in molecule of iodine (I₂), iodine has oxidation number 0, because iodine is nonpolar molecule.

3) in sodium iodide (NaI), iodine has oxidation number -1, sodium has oxidation number +1:
+1 + x = 0.
x = -1.

4) in iodic acid (HIO₃), iodine has oxidation number +5, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 3 · (-2) = 0.
x = +5.

Answer:

The sound wave travelled more quickly through the glass of water than the metal pole.

The sound wave travelled the fastest through the helium.

The sound wave travelled the slowest through the metal pole.

These 3 are most likely true.

If you have to pick just one, the sound wave travelled the fastest through the helium.

Why is it important to keep th naoh solution covered at all times?

Ber [7]

It is important to keep the NaOH solution covered at all time because sodium hydroxide is a very good remover of Carbon dioxide from the air means sodium hydroxide absorbs the carbon dioxide from the air react with that so the concentration of your solution will also change if you uncover the NaOH.
The following reaction occurs when sodium hydroxide reacts with carbon dioxide;
2 NaOH(aq) + CO2(g) --> Na3CO3(aq) + H2O(l)
