Answer:

A. internal arrangement of atoms

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.

Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

Hence, all the physical properties of a mineral result from the mineral's internal arrangement of atoms.

Suppose that the volume of a particular sample of Cl2 is 718 mL at 675 mmHg and 48C at what temperature in C will the volume be
Kryger [21]

Answer:

1900 °C

Step-by-step explanation:

This looks like a case where we can use the <em>Combined Gas Law</em> to calculate the temperature.

p₁V₁/T₁ = p₂V₂/T₂               Multiply both sides by T₂

p₁V₁T₂/T₁ = p₂V₂                 Multiply each side by T₁

p₁V₁T₂ = p₂V₂T₁                   Divide each side by p₁V₁

T₂ = T₁ × p₂/p₁ × V₂/V₁  

=====

Data:

We must convert the pressures to a common unit. I have chosen atmospheres.

p₁ = 675 mmHg × 1atm/760 mmHg = 0.8882 atm

V₁ = 718 mL = 0.718 L

T₁ = 48 °C = 321.15 K

p₂ = 159 kPa × 1 atm/101.325 kPa = 1.569 atm

V₂ = 2.0 L

T₂ = ?

=====

Calculation:

T₂ = 321.15 × 1.569/0.8882 × 2.0/0.718  

T₂ = 321.15 × 1.766 × 2.786  

T₂ = 321.15 × 1.569/0.8882 × 7.786  

T₂ = 1580K  

T₂ = 1580 + 273.15

T₂ = 1900 °C

<em>Note</em>: The answer can have only <em>two</em> significant figures because that is all you gave for the second volume of the gas.

How many moles are in 28g of Fe2O3
nlexa [21]

Find the molar mass of Fe_2O_3

2Fe = 2*56 = 112

3O = 3* 16 =    48

Molar Mass = 160 grams

moles= given mass / molar mass

moles = 28 / 160

moles = 0.175   <<<< answer
