Formation of Elements
The process when massive stars explode and produce elements heavier than iron.
What is SUPERNOVA NUCLEOSYNTHESIS?
This type of bond forms between atoms with significant differences in electronegativity. (ΔEN ≥ 1.70)
What is IONIC BOND?
The weakest type of intermolecular force because of its temporary partial polarity.
What is LONDON DISPERSION FORCE?
This type of macromolecule serves as the primary energy source for cells.
What are CARBOHYDRATES?
The minimum energy required for a reaction to occur.
What is ACTIVATION ENERGY?
The reactant that is completely consumed first, limiting the amount of product formed.
What is LIMITING REACTANT?
The process of creating new elements by combining atomic nuclei.
This molecular geometry occurs when a molecule has a central atom with no lone pairs and forms 3 bonds with bond angles of 120°.
What is TRIGONAL PLANAR?
The unusually high boiling point of water is primarily due to this intermolecular force.
What is HYDROGEN BONDING?
DNA and RNA are examples of this group of macromolecules.
What are NUCLEIC ACIDS?
It lowers the activation energy, increasing the reaction rate.
What is CATALYST?
An active ingredient of muriatic acid that is useful as cleaning agent.
What is HYDROCHLORIC ACID?
The first synthetic element discovered, identified by its presence in cyclotron experiments.
What is TECHNETIUM?
Water molecules exhibit this type of polarity due to their bent shape.
What is POLAR?
The elements that bonds with HYDROGEN to form H-Bonding. (Name all)
What is FLUORINE, OXYGEN, NITROGEN?
These biological macromolecules are composed of amino acids.
What are PROTEINS?
According to collision theory, particles must collide with sufficient energy and this to react.
What is CORRECT ORIENTATION?
Product is used to reduce microbial count on surface but not necessarily to clean the surface.
What is SANITIZER?
The heaviest naturally occurring element on Earth. (Atomic Number of 92)
What is URANIUM?
Simplified drawings of how valence electrons are arranged around atoms in a molecule.
What is LEWIS DOT STRUCTURE?
Element that gains electrons due to the sharing of electrons between itself and another element.
What is ANION?
The property of lipids which causes them to not dissolve in water because of their non-polarity.
What is HYDROPHOBIC?
Increasing this condition leads to more frequent and energetic collisions among particles.
What is TEMPERATURE?
Active ingredient of moisturizer that helps soother, soften, and increase moisture levels, especially in the skin.
What is EMOLLIENT?
The device used to accelerate particles to high speeds for element synthesis.
This rule predicts the 3D arrangement of molecules based on electron-pair repulsion.
What is VSEPR THEORY?
Substances with strong intermolecular forces tend to have higher values for these two properties.
What is MELTING POINT, BOILING POINT, SURFACE TENSION?
The bond that links amino acids in a protein is called this.
What is PEPTIDE BOND?
Name 3 out of 4 factors affecting the rate of chemical reaction.
What is ACTIVATION ENERGY, TEMPERATURE, CONCENTRATION, SURFACE AREA?
In the reaction 2Al + 3Cl₂ → 2AlCl₃, if you start with 4 moles of Al and 5 moles of Cl₂, which is the limiting reactant?
What is CHLORINE?
