The concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

We'll begin by calculating the number of mole in 20.5 g of Zn(C₂H₃O₂)₂

Mass of Zn(C₂H₃O₂)₂ = 20.5 g

Molar mass of Zn(C₂H₃O₂)₂ = 65 + 2[(12×2) + (3×1) + (16×2)]

= 65 + 2[59]

= 183 g/mol

Mole = mass / molar mass

Mole of Zn(C₂H₃O₂)₂ = 20.5 / 183

Finally, we shall determine concentration of Zn(C₂H₃O₂). This can be obtained as follow:

Mole of Zn(C₂H₃O₂)₂ = 0.112 mole

Volume = 105 mL = 105 / 1000 = 0.105 L

<h3>Concentration of Zn(C₂H₃O₂)₂ =? </h3>

Concentration = mole / Volume

Concentration of Zn(C₂H₃O₂)₂ = 0.112 / 0.105

<h3>Concentration of Zn(C₂H₃O₂)₂ = 1.067 M</h3>

Therefore, the concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

Elias could be standing on the transform boundary.

Answer: Option 1.

<u>Explanation:</u>

Transform boundaries are places where plates slide sideways past one another. At change limits lithosphere is neither made nor devastated. Many change limits are found on the ocean bottom, where they associate fragments of veering mid-sea edges. California's San Andreas issue is a transform boundary.

Transform boundaries are regions where the Earth's plates move past one another, scouring along the edges. Every one of these three sorts of plate limit has its own specific kind of flaw (or break) along which movement happens. Transforms are strike-slip issues. There is no vertical movement—just horizontal.

The temperature at which the reaction is occurring is increased

svetlana [45]

The addition of heat energy to a system always causes the temperature of that system to increase. This is always true because you are adding heat of a substance to increase its temperature. For example, you are going to drink a cup of coffee. And you wanted it hot to boost your attention. So you have to use hot water. In order for your water to become hot or warm, you need boil it in a kettle. Note that you are going to use an electric stove. The electric stove gets it energy from the source giving it a hotter temperature to the water in the kettle. You are applying heat energy to warm the water. So, the statement is true.

Which statement correctly relates two substances from this reaction?

Marta_Voda [28]

We have to know which two substances are related correctly.

The correct answer is: (C) H₃O⁺ is the conjugate acid of H₂O.

In an acid-base reaction, an acid reacts with a base and gives a conjugate base and conjugate acid. The reaction is shown below:

Acid₁ + Base₂ ⇄ Conjugate Base₁ + Conjugate Acid₂

In the reaction H₂CO₃ + H₂O ⇌ H₃O⁺ + HCO₃⁻, H₂CO₃ is an acid because it releases H⁺ ion and converts to HCO₃⁻. Here HCO₃⁻ is the conjugate base of H₂CO₃ ( according Arrhenius theory).

H₂O accepts H⁺ ion and is converted to H₃O⁺ , thus H₂O behaves as Bronsted base. So, H₃O⁺ is the conjugate acid of Bronsted base H₂O.

Hence, the correct answer is: (C) H₃O⁺ is the conjugate acid of H₂O.
