That law of mass conservation.
What is matter cannot be created or destroyed?
What are compounds?
The difference between a scientific theory and a scientific law.
What is a scientific theory describes how or why something happens, whereas a scientific law describes what is happening?
The rules for significant figures.
What is:
1. All non-zero digits are significant.
2. All zeros in front of the first 1-9 digits are not significant.
3. All zeros between 2 significant figures are significant.
4. All zeros at the end of a number and to the right of the decimal point are significant.
The formula to convert from ℃ to ℉?
What is ℃ = -5/9 (℉ - 32°)?
The law of definite proportions.
What is the proprtion of elements in any compound is always the same.
Anything that has mass and takes up space.
What is matter?
The difference bewteen accuracy and precision.
What is accuracy is an indication of how close a measurement is to the true value, whereas precision is the indication of how the scale on the measuring device that was used?
The basic rules for scientific notation.
What are:
1. Place only 1 digit (not a 0) in front of the decimal point.
2. Only significant figures go in front of the multiplication sign.
The formula used to convert from ℉ to ℃.
What is ℉ = 9/5 (℃)+ 32?
The law of multiple proportions.
What is if 2 elements combine to form different compounds, the ratio of masses of the second element that react with a fixed mass of the first element will be a simple, whole-number ratio.

The difference between a pure substance and a mixture.
What is a pure substance contains only one element or compound, whereas, a mixture contains different compounds and/or elements.
The rules for adding and subtracting significant numbers.
What is: When adding and subtracting measurements, round the answer so that it has the same precision as the least precise measurement in the calculation?
The formula used to convert Kelvin to ℉?
What is [(K-273.15) * 9]/5 +32 = ℉
A hypothesis that has been confimed with numerous experiments.
What is a scientific law?
The total number of neutrons and protons in an atom?
What is mass number?
The difference between a homogeneous and a heterogeneous mixture.
What is a homogeneous mixture has a composition that is always the same no matter what part of the sample is observed, whereas, a heterogeneous mixture has a composition that is different depending on what part of the saple is observed.
The rules for multiplying and dividing significant numbers.
What is: When multiplying and dividing measurements, round the answer so that it has the same number of significant figures as the measurements with the fewest significant figures?
The volume of box with a length, height, and width of 3.2 in, 2.4 in, and 5.5 in, respectively in liters.
What is 0.69218958336 L?
Dalton's atomic theory.
What is:
1. All elements are composed of small, indivisible particles called atoms.
2. All atoms of the same element have exactly the same properties.
3. Atoms of different elements have different properties.
4. Compounds are formed when atoms are joined together. Since atoms are indivisible, they can be joined together only in simple, whole-number ratios. ?
A substance that cannot be broken down (decomposed) into simpler components.
What is an element?
Atoms with the same number of electrons and protons but different numbers of neutrons.
What are isotopes?
