A tank of syngas produced by coal gasification contains 60.0% carbon monoxide, 30.0% hydrogen, and 10.0% carbon dioxide. What is the mass of hydrogen (in g) in 1.00 cubic meter of this syngas mixture at 1.00 atm and 25.0 °C? (1 m³ = 1000 L)

Answers

Considering the ideal gas law, the mass of hydrogen is 24.552 grams.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P× V = n× R× T

In this case, you know:

P= 1 atmV= 1 m³= 1000 Ln= ?R= 0.082[tex]\frac{atmL}{molK}[/tex]T= 25 °C= 298 °K

Replacing in the ideal gas law:

1 atm× 1000 L = n× 0.082[tex]\frac{atmL}{molK}[/tex]× 298 K

Solving:

[tex]n=\frac{1 atmx1000 L}{0.082 \frac{atmL}{molK}x298 K}[/tex]

n= 40.92 mol

The mol of syngas mixture is 40.92 mol.

Syngas mixture contains 30.0% hydrogen. So, there is a mol fraction of [tex]x_{hydrogen} =[/tex]0.3 . Thus, the mols of hydrogen in syngas mixture is calculated as:

40.92 moles of syngas mixture× 0.3= 12.276 moles of hydrogen

Finally, being the molar mass of hydrogen H₂ 2 [tex]\frac{g}{mole}[/tex], then the mass is:

[tex]12.276 molesx\frac{2 grams}{1 mole}[/tex]= 24.552 grams

In summary, the mass of hydrogen is 24.552 grams.

I'm pretty sure its just the mass of the sample divided by the molar mass

for example if I had like 7g of carbon and wanted to find the moles, I would divide the mass I have (7g) by the molar mass (the atomic mass value on your periodic table, in this case for carbon it would be 14g)

moles = [tex]\frac{mass}{molarmass} = \frac{7}{14} = 0.5\ moles[/tex]

what describes the pool of electrons in metallic bonding?

Answers

In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal. Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them.

How many atoms are in 80.45g of magnesium

Answers

Answer:

see below

Explanation:

1. 1 mol Mg = 24.31 g = 6.02 *10^23 atoms

     calculate the number of atomsin 80.45g Mg

         Numberof atoms = 6.02*10^23 Mg atoms / 24.31 g * 80.45 g

                                    = 1.99*10^24 atoms

2.1 mol C-12 = 12.01g = 6.02 * 10^23 atoms

    calculate the mass using

                                       = 12.01 g C / 6.02*10^23 atoms * 100 atoms

                                       = 1.99 * 10^-21 g

Answer:

1.9926 * 10 ^24 

Explanation:

Molar Mass - Use Periodic table!

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emiting the excess energy as light which property of metals is explained by this?​

Answers

Answer:

Lustrous

Explanation:

Metals are lustrous which gives them a property of having Shiny surfaces

The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.

What are valence electrons?

Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.

When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.

Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous  property of metals.

A sample of gas occupies 20 mL at -109 degree C. What volume does the sample
occupy at 65 °C?

Answers

Answer: V2= 41.2mL

Explanation:

Givens:

* V1= 20ml

* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K

* V2 = ??

* T2= 338.15 K

Use Charles law V1/T1 = V2/T2

Since we are looking for V2 we can rearrange the formula to

V2= (T2 x V1) /T1

V2= (338.15K x 20mL) / 164.15 K

V2= 41.2mL

NOTE:

Temperature should always be in K not in ⁰C or ⁰F

To convert from C to K use

*K= ⁰C + 273.15

Enter your C value in the ( ⁰C ) and you can get K
