uniform in its chemical composition and its properties all the way down to the microscopic level.
New cards
5
Element
A pure substance that cannot be broken down chemically into simpler substances
New cards
6
Chemical compound
Any pure material that can be broken down into simpler substances by a chemical change
New cards
7

The ________ unit for reporting temperature, however, is the kelvin (K)
New cards
8
reactants
They consist of ________ and products.
New cards
9
Physical changes
________ alter with the outer condition /state of a substance whereas Chemical changes alter the chemical make up of the substance.
New cards
10
pure material
Any ________ that can be broken down into simpler substances by a chemical change is called a chemical compound.
New cards
11
Chemical composition
________- describes what matter is made of.
New cards
12
mass
But ________ is not the only property that can be used to distinguish between objects.
New cards
13

New cards
22
RULE 1
Zeroes in the middle of a number are like any other digit; they are always significant
New cards
23
RULE 2
Zeroes at the beginning of a number are not significant; they act only to locate the decimal point
New cards
24
RULE 3
Zeroes at the end of a number and after the decimal point are significant
New cards
25
RULE 4
Zeroes at the end of a number and before an implied decimal point may or may not be significant
New cards
26
FACTOR LABEL METHOD → a quantity in one unit is converted into an equivalent quantity in a different unit by using a conversion factor that expresses the relationship between units
Starting quantity * Conversion factor = Equivalent quantity

Celsius to Fahrenheit
°F = ( (1.8°F/ °C) * °C) + 32 °F
New cards
29
specific gravity
the density of the substance divided by the density of water at the same temperature. It is unitless.
New cards
30
specific heat
