Chemistry Mini Quiz
Test your knowledge with these top questions!
What is the most abundant element in the Earth's crust?
Oxygen makes up about 46% of the Earth's crust, followed by silicon. So next time you breathe, thank the ground beneath your feet!
Which element is formed during the explosive death of a massive star in a supernova?
During a supernova, iron is formed due to fusion in the star's core. This process releases an immense amount of energy.
Which sour organic acid gives vinegar its sharp taste?
Acetic acid is produced when bacteria ferment the ethanol in alcoholic liquids. The name vinegar comes from the Old French vin aigre, meaning sour wine.
Developed at the Carlsberg brewery, what scale measures the acidity of a liquid using a range of numbers from 0 to 14?
Søren Sørensen introduced the pH scale in 1909 to monitor beer fermentation at the Carlsberg Laboratory; the notation represents the power of hydrogen ions.

Essential for balancing tartness in a recipe, what term refers to food ingredients like lemon juice with a pH below 7?
The word acid comes from the Latin acidus, meaning sour. These ingredients balance a dish by providing the tartness needed to cut through richness or excessive sweetness.
Which scientist is credited with discovering the double helix structure of DNA?
James Watson and Francis Crick were the scientists credited with discovering the double helix structure of DNA in 1953.
Which organic plastic makes clear furniture like Lucite tables?
Acrylic, or polymethyl methacrylate, is a lightweight polymer that offers better optical clarity and impact resistance than traditional glass.
Commonly tested in swimming pools, what term refers to a substance that sits at the exact middle of a pH scale from 0 to 14?
Neutral substances have a pH of 7.0, but pool water is kept at 7.2 to 7.8 to match human tears. The scale is logarithmic, so a pH of 8 is ten times more basic than pH 7.
