The following exothermic reaction is allowed to reach equilibrium. What

Fe(s) + O2 (g) → Fe3+ O2− What most likely happens during this reaction?

Musya8 [376]

Answer : The most likely happens during this reaction is, Oxidation-reduction

Explanation :

The balanced reaction will be,

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)$

In this reaction, neutral iron loses 3 electrons and oxidizes in (+3) state, $Fe^{3+}$ and neutral oxygen gains 2 electrons and reduces in (-2) state, $O^{2-}$

When iron react with oxygen gas to give iron oxide. This process is known as iron rusting. During the reaction, oxidation-reduction process occurs.

Oxidation : It is a type of chemical reaction in which a substance loses its electrons. Or we can say that in oxidation, the oxidation number increases.

Reduction : It is a type of chemical reaction in which a substance gains its electrons. Or we can say that in reduction, the oxidation number decreases.

Calculates the equivalent mass of calcium chlorate CA (CI03) 2

love history [14]

Answer:

207g

Explanation:

Given compound:

Ca(ClO₃)₂

The equivalent mass can be derived by summing the molar masses of each atom

Molar mass of Ca = 40

Cl = 35.5

O = 16

Now solve;

Molar mass = 40 + 2(35.5 + 3(16)) = 207g

Classify each of these soluble solutes as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. Solutes formula hydroch

matrenka [14]

Compounds which on dissolving in water gets completely dissociates into its ions are known as strong electrolytes whereas compounds which on dissolving in water gets partially dissociates into its ions are known as weak electrolytes.

Substances which gives solution on dissolving in water and do not dissociates into ions also does not conduct electric current are known as nonelectrolyte.

Hydrochloric acid, $HCl$

On adding $HCl$ (strong acid) in water, it will completely dissociates into ions ( $H^{+}$ and $Cl^{-}$ ) and thus, it is a strong electrolyte.

Sodium hydroxide, $NaOH$

On adding $NaOH$ (strong base) in water, it will completely dissociates into ions ( $Na^{+}$ and $OH^{-}$ ) and thus, it is a strong electrolyte.

Formic acid, $HCOOH$

On adding $HCOOH$ (weak acid) in water, it will partially dissociates into ions ( $H^{+}$ and $HCOO^{-}$ ) and thus, it is a weak electrolyte.

Methyl amine, $CH_3NH_2$

On adding $CH_3NH_2$ (weak base) in water, it will partially dissociates into ions ( $CH_3NH_3^{+}$ and $OH^{-}$ ) and thus, it is a weak electrolyte.
