PLEASE HELP "Which of the following substances would have the lower concentration of hydrogen ions ?"

Answers

Answer 1

The lower the pH, the greater the concentration of hydrogen ions (this is one of the definitions of an acid: a substance that increases the hydrogen ion concentration in water). So the answer here would be the one denoting the highest pH value, since that would indicate the smallest concentration of hydrogen ions.

That would be the substance with a pH of 11.2. Thus, the second answer choice here would be correct.

Describe the motion of the water molecules as the vapor pressure increases?

Answers

Answer: As for vapor pressure being higher at higher temperatures, when the temperature of a liquid is raised, the added energy in the liquid gives the molecules more energy and they have greater ability to escape the liquid phase and go into the gaseous phase.

Explanation:

The motion of the water molecules as the vapor pressure increases is:

The water molecules have greater energy

According to the movement of the water molecules in a pressurized environment where the vapor and the temperature are increased, there is an increased ability to change from liquid to gas.

As a result of this, the water molecules has greater energy as they are subjected to increased levels of temperature and vapor pressure which makes them have more energy and to be more unstable.

Explanation:

Since the oxidation state of Mg is changed to +2 from 0, it is oxidized. (as it is increased)

Similarly, oxidation state of Cu is changed to 0 from +2, it is reduced. (as it is decreased)

Since oxidation & reduction occur at the same time, it is redox reaction.

As Mg is being oxidized, other one must be the oxidizing agent.

Cu is the oxidizing agent

Answers

Answer:

the answer is 0.2

Explanation:

we have a formula that mole= reacting mass/ molar Mass and the molar Mass of KNO3 is 101 so since mole is reacting mass/ molar Mass and our reacting mass is 20.5 then divided it by 101 it is equal to 0.2

Explain why the properties of metals, ceramics, semiconductors, polymers, and composites need to be considered before decisions are made about which types of materials are used in a product. Enter your answer in the space provided.

Answers

Answer:

See explanation

Explanation:

In different products, different properties are desired based on the intended use of the final product.

The properties of the final product depends highly on the properties of the materials from which it was made.

For instance, when we desire a light weight product which is corrosion resistant and maintains a high tensile strength, we may consider the use of composite materials since they exhibit such properties.

Hence, the producer must consider the properties of each particular material before it is used in a product.

How to find the final product of Fe (II) + CI ?

Answers

The valency of iron (Fe) in this equation is 2

While, the valency of chlorine is 1

Therefore, we know that iron wants to give away 2 electrons to attain octet configuration, and chlorine wants to get an electron to attain octet configuration.

Also while find the products the number of atoms is similar to the oppostie valency

Fe = 1 atom , Cl = 2 atoms

Which will form FeCl₂

the equation demonstrates a reaction of sodium chloride and fluorine. 2NaCl+F2=2NaF+Cl2. in order for the reaction to proceed, for every two moles of sodium chloride, there must be at least how many mole(s) for fluorine

Answers

Answer: You would need 1 mole of Fluorine

Explanation:The equation is already balanced so just looking at the coefficients in the equation we can see that Sodium Chloride (2NaCl) needs two moles for this equation and fluorine (F2) only needs one.

In order for the reaction to proceed, for every two moles of sodium chloride, there must be at least 1 mole for fluorine.

Balanced chemical reaction:

2NaCl + F₂ → 2NaF + Cl₂

The reaction given above is balanced. When 2 moles of sodium chloride reacts with 1 mole of fluorine produces 2 moles of sodium fluoride and 1 molecule of chlorine.

Thus, two moles of sodium chloride, there must be at least 1 mole for fluorine.

What is the pH of an aqueous solution that has an H+ ion concentration of 0.10 M?
14
10
6
1

Answers

Answer:

Explanation:

pH = -log[H+] = -log(0.10) = log(1.0 x 10^-1) = 1

The pH scale determines how acidic or basic water is. The pH of an aqueous solution that has an H+ ion concentration of 0.10 M is 1. Therefore, option D is correct.

What is pH ?

The pH scale, which previously stood for "potential of hydrogen," is used to describe how acidic or basic an aqueous solution is. The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave.

pH = -log [ H ⁺ ] = -log ( 0.10 )

= log ( 1.0 x 10⁻¹ )

= 1

Thus, The pH of an aqueous solution that has an H+ ion concentration of 0.10 M is 1. Therefore, option D is correct.
