Which equation is balanced?
A. H 2 + O 2 → H 2O
B. 2Na + Cl 2 → 2NaCl
C. KClO 3 → KCl 2 + 3O 2
D. CH 4 + 2O 2 → CO 2 + H 2 O

Answers

B. is the correct answer

Because in both sides (reactant and product) are:
Na= 2. Na=2

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.

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

Answers

Answer:

1

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.

Answers

The coefficient is 2.
Full equation is

The balanced equation is 2Na + 2H[tex]_2[/tex]O [tex]\rightarrow[/tex] 2NaOH + H[tex]_2[/tex] and the coefficient of H[tex]_2[/tex]O is 2. Stoichiometry represents the number of coefficients.

What is balanced equation?

An equation for just a chemical reaction is said to be balanced if both the reactants as well as the products have the same number of atoms and total charge for each component of the reaction. In other words, each sides of both the reaction have an equal balance of mass and charge.

It is typical that balancing chemical formulas for both charge and mass in aqueous solutions. Equal numbers and types of atoms are produced on both aspects of the equation when balancing for mass. When the charge is balanced, there is no net charge on either side of the equation.

The balanced equation can be written as

2Na + 2H[tex]_2[/tex]O = 2NaOH + H[tex]_2[/tex]

The coefficient of H[tex]_2[/tex]O is 2.

Therefore, the balanced equation is 2Na + 2H[tex]_2[/tex]O [tex]\rightarrow[/tex] 2NaOH + H[tex]_2[/tex] and the coefficient of H[tex]_2[/tex]O is 2.

What is a chemical change?

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

a) why is this a redox reaction?

b) identify the oxidizing agent. Give reason for your answer

answer any of them you want please

Answers

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

Kindly check the explanation section.

Explanation:

PS: Note that enough information are not being provided and we do not know the experiment this question is all about. However, some information are provided below which is going to aid in solving when you get access to the main question.

The determination of the heat transferred from one substance to another is one of the important aspect in science. The method in which this heat is being measured is known as calorimetry and the instrument used in this technique is known as the calorimeter.

When the energy content of a snack is needed to be calculated, there is the need use a type of instrument known as bomb calorimeter.

Most of the calorimeters used by students are not so expensive like the used in the industries. Most of these calorimeters operates at a constant pressure while the Bomb Calorimeter operates at constant volume.
