Introduction to Chemistry
It is the study of matter - its properties, how it behaves, how it is put together, and how it can changed or rearranged.
What is Chemistry?
The definition of matter.
What is anything that has mass and takes up space?
Another name for particulate.
What is particle?
The three primary states of matter
What is solid, liquid, and gas?
It is defined as the movement of particles from a region of higher to lower concentration until evenly distributed.
What is diffusion?
Give 2 examples of chemistry in everyday life.
Food, cleansing agents, cosmetics, elements in human body
The basic building blocks of matter.
What are atoms?
Pressure, volume, and temperature are examples of what kind of observable properties?
Hint: it can be seen without the use of a microscope
What are observable macroscopic properties?
Its particles vibrate or jiggle in a fixed position but do not move from place to place because of its rigid nature
What are solids?
Often referred to as the fourth state of matter.
What is plasma?
This branch of chemistry is responsible for studying compounds such as salts and minerals.
What is inorganic chemistry?
Which of the following are examples of matter?
Air, gravity, time, energy, rocks, water, neon, sound
What are air, rocks, water, neon?
What the particulate theory of matter also is known as.
What is the particle molecular theory of matter?
Its rate of diffusion and kinetic energy is higher than the other two states of matter.
What are gases?
It is the movement of water particles or molecules from a region of higher to lower concentration through a semi-permeable membrane.
What is osmosis?
The definition for computational chemistry.
What is the use of computer simulation to solve chemical problems?
The definition of a molecule.
What is a group of two or more atoms linked together by sharing electrons in a chemical bond?
The experiment that is popular to help bring evidence in support of the particulate nature of matter.
What is the analysis of the reaction between ammonia and hydrochloric acid?
Its kinetic energy and intermolecular force is intermediate.
What are liquids?
What IMF stands for and its definition.
Intermolecular force
- The force of attraction between molecules
True or False: water, nitrogen, and helium ion are examples of molecules.
What is False?
Helium ion is not an example of a molecule
These three particles make up an atom.
What are electrons, neutrons, and protons?
Give 3 of 5 assumptions made by the particulate theory of matter.
What are:
- All matter is made up of small particles known as atoms - pure substances have unique or specific particles - particles attract each other and have spaces between them - particles are constantly in motion - as temperature increases, particles of matter move faster
It is a function of the temperature of a substance and keeps the molecules apart and moving around.
What is the kinetic energy?
The physical property that DOES depend on how much matter a sample contains.
Give 2 examples as well.
What is the extensive property?
- weight, length, volume, mass, density, shape
