period 2 Flashcards
(32 cards)
What was the first country to
ban PFAS in food packaging?
Denmark
What are the main impacts of
PFAS?
all of the above (Cancer, Immune suppression, Elevated cholesterol levels, Liver damage)
What is a positive void
coefficient, and how does it affect a reactor
A positive void coefficient is when water
boils and evaporates creating a “void”. it
causes reactors to become unstable since
it would not have as much power in slowing
down the reactions, causing a positive
feedback loop
What is the process of the
RBMK reactor and how does it
create energy?
The RBMK reactor uses
nuclear fission on uranium-235
to boil water, where the water
vapour would go through a tube
and spin the turbine, generating
electricity
What caused the hydrogen gas explosions at Fukushima?
Chemical reactions between zirconium fuel rods and water
What new technology is being used to prevent water contamination from the site?
Frozen soil walls or “ice walls.”
What was 1 radioisotope that was released due to the destablization of the
fission reaction?
Iodine-131, or cesium-137
What is the chemistry of a nerve agent?
It inhibits an enzyme in the nervous system that prevents proper transmission between nerve receptors.
How do nerve agents enter your system?
Through the skin and the eyes as liquids, through the lungs if breathed in
What element does white phosphorus react with in order to burn?
Oxygen gas
Name 2 chemical properties of dichlorine that make it a good chemical weapon
Volatile, high melting and
boiling point, gaseous, reactive,
soluble
How do synthetic dyes and iron oxides enhance the color and safety of
lipstick?
Synthetic dyes and iron oxides provide vibrant, long-lasting color to lipstick. Iron
oxides are particularly favored for their stability and safety, as they are non-toxic and
less likely to cause irritation compared to other colorants
How has augmented reality (AR) technology impacted the modern lipstick industry, particularly in terms of customization
Allows users to virtually try on lipstick shades before purchasing, enhancing the
shopping experience.
Leading cause of death in the world?
Heart disease/cardiovascular disease
What happens in phase 2 of decomposition?
Bacteria produces gasses
Which is responsible for bloating after death
gas release from bacterial activity
What causes rigor mortis after death
Lack of ATP
What two chemicals are most commonly used in basic spherification?
Sodium alginate and calcium chloride
What makes liquid nitrogen a great choice when making ice cream?
Liquid nitrogen’s rapid freezing, due to its extremely low boiling point, produces smaller ice crystals for a smoother, creamier ice cream
What are the products of the reaction which
occurs when chlorine gas is inhaled?
Hypochlorous acid + Hydrochloric acid
What type of organism produces cyanide in the
form of toxic microcystins?
Blue-green algae
Who was the first person to synthesize LSD (lysergic acid diethylamide)?
Albert Hoffman
What is the neurotransmitter that psychedelics mimic in the brain?
Serotonin
Which psychedelic was originally developed as
an anesthetic?
Ketamine
