Silver bromide (AgBr) has a solubility of 7.07 × 10^-7 mol/L
kirill115 [55]

a. AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b.  Ksp AgBr = s²

c. 5 x 10⁻¹³  mol/L

<h3>Further explanation</h3>

Given

solubility AgBr = 7.07 x 10⁻⁷ mol/L

Required

The dissolution reaction

Ksp

The solubility product constant

Solution

a. dissolution reaction of AgBr

AgBr(s)⇒ Ag⁺(aq) + Br⁻(aq)

b. Ksp

Ksp AgBr  = [Ag⁺]  [Br⁻]

Ksp AgBr = (s) (s)

Ksp AgBr = s²

c. Ksp AgBr = (7.07 x 10⁻⁷)² = 5 x 10⁻¹³  mol/L

A galvanic cell generates a cell potential of 0.32V when operated under standard conditions according to the reaction above. Whi
Ugo [173]

The complete question is shown in the image attached to this answer.

Answer:

C

Explanation:

Let us quickly remember that the EMF of a cell under non standard conditions in given by the Nernst equation.

This equation states that;

E = E°cell - 0.592/n log Q

Where

E = EMF under non standard conditions

E°cell= standard EMF of the cell

n = number of electrons transferred

Q = reaction quotient

If the reaction quotient is greater than 1 then cell potential is less than the standard cell potential.

The cell that generates the lowest cell potential is the cell depicted in option C because Q has the greatest positive value(Q<1).

Read the following chemical equation. Mg(s) + H+ Cl− → Mg2+ Cl− + H2 What most likely happens during this reaction?
spin [16.1K]

Answer:

Magnesium loses two electrons.

Explanation:

  • As clear from the reaction Mg converted from <em>Mg(s) to Mg²⁺</em>, so Mg converted from the oxidation state (0) to (2+).

<em>∴ Mg losses two electrons.</em>

  • Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.

<em>So, the correct choice is Magnesium loses two electrons.</em>

What is technology?
ella [17]

Something created for using science for use by society. Hence, option A is correct.

<h3>What is science?</h3>

Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

Technology is the use of science to provide human problem. It can be in the form of a machine, tool or equipment. As long as it involves applying a scientific process, it's technology.

Example of technology is a computer. It's used to store and process data in a faster way. Old technology also included Hammer, Saw, Grinding Machines etc.

Hence, option A is correct.
