A sample of solid ammonium chloride decomposes on heating
solid ammonium chloride = ammonia gas + hydrogen chloride gas
A total of 2.4 * 10^21 molecules of gas is formed
How many hydrogen atoms are present in the gaseous products

Answers

Answer 1

The atoms of hydrogen in the products is 2.4 * 10^21  atoms of hydrogen

What is decomposition?

The term decomposition has to do with a type of reaction in which a substance is broken down into into its components.

The decomposition of ammonium chloride occurs as follows;

NH4Cl → NH3 + HCl

If 6.02 * 10^23 hydrogen atoms are present in  6.02 * 10^23  molecules

x hydrogen atoms are present in 2.4 * 10^21 molecules

x = 2.4 * 10^21  atoms of hydrogen

The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:

15 moles of Cu10 moles of P40 moles of O

Description of Cu₃(PO₄)₂1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu2 moles of P(2×4) = 8 moles of O

How to determine the mole of each atom

The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow

For Cu

As consumption of a synthetic material increases, the associated negative impacts to Earth required to produce the material increase.

Answers

Is this a true or false question? If so, then this would be a true statement. Synthetic materials are made in factories, and the usage of factories increases the risks of harmful gases and chemicals that negatively impacts Earth.

It is generally true that as consumption of a synthetic material increases, the associated negative impacts to Earth needed to produce the material also increase.

Why the given sentence is true?

This is because the production of synthetic materials often requires the extraction and processing of non-renewable resources, such as petroleum, which can have a range of negative environmental impacts, including habitat destruction, air and water pollution, and greenhouse gas emissions.

Additionally, the disposal of synthetic materials can also lead to environmental problems, such as the accumulation of non-biodegradable waste in landfills and oceans.

However, it is important to note that not all synthetic materials have the same environmental impacts, and some materials may be more sustainable than others depending on their production methods and intended use. Hence, the given sentence is true.

A soft drink contains 12.1% sucrose (C12H22O11) by mass. What volume of the soft drink solution in milliliters contains 102.5 g of sucrose? (Assume a density of 1.04 g/mL)

Answers

The volume of the soft drink solution in milliliters that contains 102.5 g of sucrose is 11.93mL.

How to calculate volume?

The volume of a solution can be calculated by dividing the mass by the density. That is;

Volume = mass/density

According to this question, a soft drink contains 12.1% sucrose (C12H22O11) by mass. This means that the mass of the sucrose is

12.1/100 × 102.5 = 12.40g of sucrose

Volume = 12.40g ÷ 1.04g/mL

Volume = 11.93mL

Therefore, the volume of the soft drink solution in milliliters that contains 102.5 g of sucrose is 11.93mL.

Use Lewis symbols to predict the formula for the
compound that forms between magnesium and
nitrogen

Answers

The lewis structure of Magnesium nitride places eight electrons around N. 3 of these electrons are provided by Mg to get a stable conformation.

What is the Lewis structure?

The Lewis structure is a representation of electron pairs in bonds between the atoms that compose the molecule. It can also show the solitary electron pairs that remain for each atom.

Electrons

When adding the valence electrons of each atom, we get the total number of electrons in the molecule.

The valence value is the number of electrons placed in the last energetic level of the atom.

The compound that forms between magnesium and nitrogen is magnesium nitride, Mg₃N₂. This is a simple salt with an ionic bond between a metal and a non-metal element.

What are the Metalic atoms?

They are elements that express a tendency to lose valence electrons to get a stable electronic configuration. When they lose electrons, they remain positively charged. These are cations with positive charges and lose the valence electrons of their last level.

Mg has 2 electrons in its last level, so to get a complete stable configuration (2e-), it needs to lose 2 electrons.

Mg has two positive charges Mg ²⁺

What are the non-metalic atoms?

They are elements that gain electrons to complete their last level. These are the anions. When they get electrons, they remain negatively charged.

Because Nitrogen has 5 electrons in its last level, it needs to add 3 electrons. In this way, it gets to the complete stable configuration (8e-).

N has three negative charges N³⁻

So, to complete the Lewis structure, we need to add Mg ²⁺ and N³⁻.

We know that

Mg loses two electrons,N needs to add three electrons.

According to this, N needs more than one Mg to complete its last level.

So, in our calculations, we need to have three Mg and two N.

Two N need six electrons (-3e- x 2 = -6e-) to complete their last levelThree Mg can provide six electrons (+2e- x 3 = +6e-)

You will find the final Lewis structure in the attached files.

175 ml of a 1.6 m solution of kcl is diluted to a new volume of 1.0 l. what is the new concentration of the solution?

Answers

The new concentration of the KCl solution after mixing 1 L new volume is 0.28 M.

How do we calculate the concentration?

Concentration in terms of molarity will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

M₁ = molarity of old KCl solution = 1.6 M

V₁ = volume of old KCl solution = 175 mL = 0.175 L

M₂ = molarity of new KCl solution = ?

V₂ = volume of new KCl solution = 1 L

On putting all these values on the above equation, we get

M₂ = (1.6)(0.175) / (1) = 0.28 M

Hence resultant concentration is 0.28 M.
