Basics of Chemistry
This is the systematic study of the materials of the universe and their changes.
What is chemistry?
This is the possible solution to a problem. It must be testable, and it must be rejected or corrected when it conflicts with experiment.
What is a hypothesis?
This is the representation of a number in the form of A x 10^n
What is scientific notation?
This is any zero that comes after the last non-zero digit in a numerical value.
What is a trailing zero?
This is the SI unit for length.
What is a meter?
This is the level at which atoms and molecules are described.
What is the microscopic level?
This is an operation conducted under controlled conditions that is intended to test a hypothesis. It must be repeatable and reproducible.
What is an experiment?
This is the prefix that means one millionth.
What is micro?
This is the type of zero that appears before the first non-zero digit in a numerical value. You do not count these zeros when counting significant figures.
What is a leading zero?
This is the SI unit for weight.
What is a gram?
This is a written account intended for professionals. An example of this would be the Journal of Organic Chemistry.
What is a primary source?
This is the foundation of the scientific method. It can be qualitative or quantitative. It is also known as data.
What are observations?
This is the range of values that "A" represents in scientific notation, which is represented by the general form A x 10^n.
What is between 1 and 9.99?
This type of number has an infinite number of significant figures.
What is an exact number?
This is the prefix that means one billionth.
What is nano?
Solve this problem:
(3.54 x 10^-12)(2.8+7.56)/(6.994 x 10^-7)
5.2 x 10^-5
This is the discipline of science that studies the structure, properties, and reactions of compounds and materials that contain carbon and hydrogen.
What is organic chemistry?
This is a statement that scientists can demonstrate to be true. It cannot be disproven.
This is the state of the exponent in scientific notation that represents a very large number. When you see the exponent's power, you move the decimal place to the right.
What is a positive exponent?
This is the rule for significant figures when you multiply or divide numbers.
What is keeping the lowest number of significant figures?
This is the prefix that means one thousandth.
What is milli?
What is alchemy?
This is a well-tested and validated explanation for data based on a set of hypotheses and an accumulation of data. It embodies predictions on what will happen.
What is a theory?
This is the state of the exponent in scientific notation that represents a very small number. When you see the exponent's power, you move the decimal place to the left.
What is a negative exponent?
This is the rule for significant figures when you add or subtract numbers.
What is keeping the lowest amount of decimal places?
This is the amount of certainty you have for exact numbers or when you define certain units. An example of this would be that there is exactly 1.61 km in one mile, exactly 3 feet in one yard, or exactly 12 inches in one foot.
What is completely certain/no uncertainty?
