Classify each example of molecular art as a pure element, a pure compound, or a mixture.
(a)
Interpretation:
The molecular art has to be classified as a pure element, a pure compound or a mixture.
The given molecular art is,
Figure 1
Concept Introduction:
Matter can be classified into two type’s namely pure substance and mixture.
Pure substance: A single component that has a constant composition, irrespective of the sample size and the sample origin is called as pure substance. A pure substance could not be broken down to other pure substances by any physical change.
Example: Water, sugar etc.
Element: A pure substance, which cannot be broken down into smaller substances by a chemical reaction is called as an element.
Example: Hydrogen gas, Magnesium ribbon and copper wire etc.
Mixture: A mixture consists of more than one substance and the composition of a mixture is dependent on the sample. The separation of mixture into its components can be done by physical changes.
Compound: A pure substance that is formed by combination of two or more elements by chemical process is called as a compound. Example: Sodium chloride is a compound because it is formed from elements sodium and chlorine.
Answer to Problem 1.31UKC
The given molecular art is a pure element.
Explanation of Solution
The given molecular art is,
Figure 1
The molecular art shown above is a pure element because it comprises of only single entity.
(b)
Interpretation:

(c)
Interpretation:
The molecular art has to be classified as a pure element, a pure compound or a mixture.
The given molecular art is,
Figure 3
Concept Introduction:
Refer to part (a).
Answer to Problem 1.31UKC
The given molecular is a mixture.
Explanation of Solution
The given molecular art is,
Figure 3
The molecular art shown above is a mixture because it comprises of more than one component (different types of molecules).
(d)
Interpretation:
The molecular art has to be classified as a pure element, a pure compound or a mixture.
The given molecular art is,
Figure 4
Concept Introduction:
Refer to part (a).
Answer to Problem 1.31UKC
The given molecular art is a mixture.
Explanation of Solution
The given molecular art is,
Figure 4
The molecular art shown above is a mixture because it consists of more than a single component (different types of atoms).

If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.arrow_forward

To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard with the new method returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Does the new method produce a result that is significantly different from the standard value at the 95% confidence level?arrow_forward
