ICE Princess25 [194]3 years ago
7 0

Explanation:

A bronsted lowry acid is any species that can donate a hydrogen proton (H+) to another molecule.

A bronsted lowry base is any species that can receive a hydrogen proton (H+) from another molecule.

a. hbr h2o --> h30+ br-

The Bronsted-Lowry acid is HBr

It's conjugate base is Br-

The Bronsted-Lowry base is H2O

It's conjugate acid is h30+

b. NO-2 H2o --> HNO2 OH-

The Bronsted-Lowry acid is H2O

It's conjugate base is OH-

The Bronsted-Lowry base is NO-2

It's conjugate acid is HNO2

Which statement is always true of the cathode in an electrochemical cell? Reduction occurs here. It is considered the "negative"
lara31 [8.8K]

Answer:

It Is Considered The "negative" Electrode

Explanation:

An electrochemical cell is an electrolytic cell that drives a non-spontaneous redox reaction through the application of electrical energy. This cell is used to decompose chemical compounds, in a process called electrolysis. An electrode at which reduction take place is called the cathode. In reduction, electrons travel toward the site of reduction such that the negative charge is on the cathode.

The rate constant for a reaction is 4.65 L mol-1s-1. What is the overall order of the reaction? zero
il63 [147K]

Answer:

second order

Explanation:

units of reaction and their order.

Zero order --> M^1 s^-1 = M/s

First order --> M^0 s^-1 = 1/s

Second order --> M^-1 s^-1 = L/mol s

In the question rate constant k =  4.65 L mol-1s-1. = 4.65 L/mol s

Hence, the reaction is a second order reaction

"determine the mass of oxygen" in a 7.9 g sample of al2(so4)3.
jeyben [28]

Answer:

              4.43 g of Oxygen

Explanation:

As shown in Chemical Formula, one mole of Aluminium Sulfate [Al₂(SO₄)₃] contains;

                          2 Moles of Aluminium

                          3 Moles of Sulfur

                          12 Moles of Oxygen

Also, the Molar Mass of Aluminium Sulfate is 342.15 g/mol. It means,

          342.15 g ( 1 mole) of Al₂(SO₄)₃ contains  =  192 g (12 mole) of O

So,

                         7.9 g of Al₂(SO₄)₃ will contain  =  X g of O

Solving for X,

                       X  =  (7.9 g × 192 g) ÷ 342.15 g

                      X =  4.43 g of Oxygen
