Chemistry Basics
This number tells you how many protons are in an atom, which also determines its element identity.
atomic number
This foundational law states that matter cannot be created or destroyed, requiring us to always balance chemical equations.
Response: What is the Law of Conservation of Mass
This acronym is used in optics to describe the four characteristics of an image: ____. It stands for ____.
SALT. Size, Attitude, Location and Type
This term describes the bending or change in direction of light as it passes obliquely from one optical medium into another.
Refraction
These abnormal cells differ from healthy cells because they ignore chemical signals and divide rapidly and uncontrollably, forming tumors.
Cancer
Unlike ionic bonds, these types of compounds are formed when non-metal atoms share valence electrons.
molecular (or covalent) compounds
A fast chemical reaction where a substance reacts rapidly with oxygen, releasing heat and light, often producing CO2 and H2O
combustion
On the electromagnetic spectrum, light waves with the highest energy always have this corresponding trait regarding their wavelength.
Response: What is the shortest wavelength? (Or high frequency).
This natural optical phenomenon occurs when sunlight undergoes both refraction and total internal reflection inside falling raindrops.
Rainbow
While animal and plant cells are eukaryotic, bacteria belong to this cellular category, which lacks a nucleus and membrane-bound organelles.
prokaryotes
This acronym helps students remember the seven diatomic elements that naturally exist as pairs, such as Hydrogen and Oxygen.
HOFBrINCl
A chemical reaction that yields a salt and water when an acid and a base are mixed together.
neutralization
According to the Law of Reflection, the angle of incidence is always equal to this other angle.
angle of reflection
Light travels from air into a diamond ($n = 2.42$). Describe whether the light bends toward or away from the normal line.
towards
This is the precise sequence of the 4 main stages of Mitosis where a cell divides its copied DNA.
Prophase, Metaphase, Anaphase, and Telophase? (PMAT)
What is the chemical formula for Aluminum Oxide
Al 2 O3
Balance the following chemical equation: H2+ O2=H2O
2H2 + O2 = 2H2O
This specific type of curved mirror converges light rays to a single focal point and can create both real and virtual images
concave
This phenomenon happens when light travels from a slower medium to a faster medium at an angle greater than the critical angle, causing 100% of the light to reflect back.
Total internal reflection
This is the correct biological hierarchy representing the structural levels of organization in a complex multicellular organism, starting from the smallest unit.
Response: What is cell $\rightarrow$ tissue $\rightarrow$ organ $\rightarrow$ organ system $\rightarrow$ organism?
Describe or draw the Electron Dot (Lewis) structure for a stable Magnesium ion after it has achieved a full valence shell.
Mg enclosed in square brackets with a superscript of 2+ outside the brackets, showing zero valence electrons remaining in its original outer shell
If a solution has a pH of 3, it is classified as this, and it possesses a high concentration of these specific ions.
Response: What is an acid / hydrogen ions (H+
This type of light emission occurs when an object is heated to such a high temperature that it begins to glow, like an old incandescent lightbulb.
incandesence
Calculate the index of refraction (n) for a substance where the speed of light is 2.0 x 10^8m/s.
1.5
his organ system interacts directly with the respiratory system to pick up oxygen from the alveoli and drop off carbon dioxide via the blood.
