Answer:
- <em><u>The rate that SO₂ (g) reacts equals the rate that SO₃ (g) decomposes</u></em>.
Explanation:
The chemical equation for the reaction of sulfur dioxide and oxygen to produce sulfur trioxide is given:
- SO₂ (g) + O ₂ (g) ⇄ SO₃ (g)
The double arrow is indicating that this is an equilibrium reaction, which means that, once the reactants start to react, two reactions occur simultaneously:
- Direct or forward reaction:
SO₂ (g) + O ₂ (g) → SO₃ (g) . . . [the arrow goes from left to right]
SO₂ (g) + O ₂ (g) ← SO₃ (g) . . . [the arrow goes from right to left]
The chemical equilbrium is a dynamic equilibrium, which means that the species (reactants and products) do not remain static but they continue reacting: the rate of both direct and reverse reactions are equal, so in net terms the concentrations do not change.
A graph of reaction rate versus time shows the concentrations of reactants and products over time. Before reaching the equilibrium, the concentrations of reactants will decrease and the concentrations of products will increase, but when the equilibrium is reached the concentrations will remain constant, because, as explained the rate of both forward and reverse reactions are equal.
For the given equation, that means that SO₂ (g) (reactant in the forward reaction) will be consumed at the same rate that SO₃ (g) (reactant in the reverse reaction) will be decomposing.
Answer:
D.141 g
Explanation:
Given that:-
Mass of ethylene = 45.0 g
Molar mass of ethylene = 28.05 g/mol
The formula for the calculation of moles is shown below:
Thus,
![Moles= 1.60\ mol](https://tex.z-dn.net/?f=Moles%3D%201.60%5C%20mol)
According to the reaction below:-
![C_2H_4+3O_2\rightarrow 2CO_2+2H_2O](https://tex.z-dn.net/?f=C_2H_4%2B3O_2%5Crightarrow%202CO_2%2B2H_2O)
1 mole of ethylene produces 2 moles of carbon dioxide
So,
1.60 mole of ethylene produces 2*1.60 moles of carbon dioxide
Moles of carbon dioxide = 3.2 mol
Molar mass of carbon dioxide = 44.01 g/mol
Mass = Moles*Molar mass = 3.2 mol x 44.01 g/mol = 141 g
<u>D.141 g of carbon dioxide will be produced</u>
The metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.
<h3>What is a compound?</h3>
A compound is made up of two or more atoms that are chemically combined together. In this case, we have the atoms; Potassium and Chlorine.
The electronic configuration of the atoms is not shown here but the metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.

Answer:
8.5 mol H₂SO₄
Explanation:
It seems the balanced reaction the problem is referring to is absent, however the description matches the following balanced reaction:
- 2SO₂ + O₂ + 2H₂O → 2H₂SO₄
Now we <u>can convert 8.5 moles of SO₂ into moles of H₂SO₄</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 8.5 mol SO₂ *
= 8.5 mol H₂SO₄
Answer:
A) Ethanoic acid and ammonium chloride.
Explanation:
Amides go through acid hydrolysis to produce carboxylic acid and ammonia by heating in aqueous acid. The acid hydrolysis reaction is produced through the <u>nucleophilic addition of water to the protonated amide</u>, then comes the transference of a proton from the oxygen to the nitrogen to make nitrogen a better leaving group, and finally, the subsequent elimination (see attachment).
In this case, the products formed with the reaction of ethanamide and aqueous HCl will be <u>ethanoic acid and ammonium chloride</u>.
