how many liters of bromine are needed to produce 12 moles of Aluminum bromide? The density of bromine is 3.1 m/gl​

Chemistry

Lorico [155]4 years ago

Answer:

0.94 L

Explanation:

Step 1: Write the balanced reaction

2 Al + 3 Br₂ = 2 AlBr₃

Step 2: Calculate the moles of Br₂ required to produce 12 moles of AlBr₃

The molar ratio of Br₂ to AlBr₃ is 3:2. Then,

12molAlBr_3 \times \frac{3molBr_2}{2molAlBr_3} =18molBr_2

Step 3: Calculate the mass of bromine corresponding to 18 moles

The molar mass of bromine is 159.81 g/mol. Then,

18mol \times \frac{159.81g}{mol} =2.9 \times 10^{3} g

Step 4: Calculate the volume of bromine corresponding to 2.9 × 10³ g

The density of bromine is 3.1 g/mL. The volume of bromine is:

2.9 \times 10^{3} g  \times \frac{1mL}{3.1g}  \times \frac{1L}{1000mL} = 0.94 L

What is the correct equation for the reaction quotient of the following reaction? 2Fe3+(aq) + Zn(s) ⇌ 2Fe2+(aq) + Zn2+(aq)
Ira Lisetskai [31]

Explanation:

A reaction quotient is defined as the ratio of concentration of products over reactants raised to the power of their stoichiometric coefficients.

A reaction quotient is denoted by the symbol Q.

For example, 2Fe^{3+}(aq) + Zn(s) \rightleftharpoons 2Fe^{2+}(aq) + Zn^{2+}(aq)

The reaction quotient for this reaction is as follows.

            Q = \frac{[Fe^{2+}]^{2}[Zn^{2+}]}{[Fe^{3+}]^{2}}

[Zn] will be equal to 1 as it is present in solid state. Therefore, we don't need to write it in the reaction quotient expression.

The solvolysis of t-butyl bromide in methanol yields 2-methylpropene in an E1 reaction (among other products). What is the effec
jolli1 [7]

Answer:

See explanation

Explanation:

For a reaction that proceeds by E1 mechanism, the rate determining step involves the formation of the carbocation.  

The rate of formation of this carbocation depends only on the concentration of the t-butyl bromide since it is the only specie that enters into the rate equation.

Hence, when the concentration of t-butyl bromide is tripled, the rate of reaction is tripled.

Methanol does not enter into the rate equation hence doubling its concentration does not affect the rate of reaction.

Is silver tarnishing a physical change or a chemical change?​
Shalnov [3]

Answer:

chemical

Explanation:

Some bronze objects tarnish to a dark brown color. Chemical properties can be identified by the changes they produce. The change of one substance into another substance is called a A piece of wood burning, an iron fence rusting, and a silver spoon tarnishing are all examples of chemical changes.
