Fe(s)+ 2 HC2H3O2(aq) → Fe(C2H3O2)2(aq) + H2(g) Which substance is reduced and which subject is oxidized?
Vlada [557]

Answer:

- Iron is oxidized from 0 to +2.

- Hydrogen is reduced from +1 to 0.

Explanation:

Hello,

In this case, for the given reaction, we must first indicate the oxidation state of each element (notice that HC2H3O is acetic acid)

Fe ^0(s)+ 2 H^+(C_2H_3O_2)^-(aq) \rightarrow  Fe^{2+}(C_2H_3O_2)_2^-(aq) + H_2^0(g)

Thereby, notcing that iron is alone at the beginning, it has zero as its oxidation state, but once the reaction is undergone, it changes to +2, moreover, the displaced hydrogen in the acetic acid is with +1 but after the chemical reaction it becomes alone for which its oxidation state is 0, thereby, we find that:

- Iron is oxidized from 0 to +2.

- Hydrogen is reduced from +1 to 0.

Best regards,

Be sure to answer all parts. Consider the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g)ΔH = −198.2 kJ/mol How would the concentrations of S
andrew-mc [135]

Answer:

a)

[SO2]: The concentration increases

[O2]: The concentration increases.

[SO3]: The concentration decreases.

b)

[SO2]: The concentration decreases.

[O2]: The concentration decreases.

[SO3]: The concentration increases.

c)

[SO2]:There is no change.

[O2]: There is no change.

[SO3]: There is no change

Explanation:

For an exothermic reaction, increase in temperature decreases the concentration of products and increases the concentration of reactants since increase in temperature shifts the equilibrium position to the left hand side.

Increase in pressure and decrease in volume will shift the equilibrium position towards the right hand side which means more SO3 in the system.

Catalyst increases the rate of forward and reverse reaction simultaneously hence at equilibrium, the concentration of reactants and products remain unchanged.

1. What is the theory that is accepted as a true<br> called? I
Harlamova29_29 [7]

Answer: Scientific Theory

Explanation:

A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. People commonly use the word theory to describe a guess about how or why something happens.
