flint striker
used to light bunsen burner
bunsen burner
used to heat chemicals in beakers or test tubes
thin stem pipette
used in micro experiment to transfer small amounts of liquid
calorimeter
burns food to count calories
relative atomic mass
the mass of an atom of a chemical element expressed in atomic mass units
avogadro's #
6.02 x 10^23 minus the # of particles in exactly one mole of a pure substance
buret
used to withdraw and measure volumes of solutions in titrations
graduated cylinder
instrument used to measure volume of a liquid
lab coat / apron
protects the scientist and the scientist's clothes from hazardous or hot chemicals
y-axis
the vertical axis on a coordinate plane
ring stand
a support with many uses
goggles / safety glasses
protects your eyes
atomic #
the # of protons in each atom of an element
beaker
used as a container , like a cup ; may be heated
iron ring
fastens to the ring stand for support for apparatus
resulting responsive
responds to another action & is the result
double beret clamp
used to hold berets when titrating
manipulated variable
the one we control (usually time)
neutron
a subatomic particle of about the same mass as a proton but without an electric charge present in all atomic nuclei except those of ordinary hydrogen
electron
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids
atom
the smallest particle of an element that retains the chemical properties of that element
mole
the amount of a substance that contains as many particles as there are atoms in exactly 12 g of carbon-12
constant
something that stays the same
spatula
used to transfer solid chemicals in weighing
florence flask
used to store liquids
crucible & cover
porcelain; used to heat small amounts of solid substances at high temperatures
dalton's atomic theory
1. all matter is composed of extremely small elements called atoms 2. atoms of an element are identical in size , mass , and other properties ; atoms of different elements differ in size , mass , and other properties 3. atoms cannot be sub-divided , created , or destroyed 4. atoms of different elements combine in simple whole-number ratios to form chemical compounds 5. in chemical reactions , atoms are combined , separated , or rearranged
gloves
used to be cleanly & to protect your hands
proton
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
dependent variable
depends on something else modifying it
electrons
atomic # - charge
thermometer
an instrument used to measure temperature
mass #
the total # of protons & neutrons that make up the nucleus of an isotope
tongs
used to pick up and hold apparatus
erlenmeyer flask
used to hold liquids , has narrow neck to prevent splashes , can be heated
molar mass
the mass of one mole of a pure substance
triangle
used to support the crucible
isotope
atoms of the same element that have different masses
nucleus
the positively charged central core of an atom , consisting of protons & neutrons & containing nearly all its mass
buret clamp
used to hold apparatus , may be fastened to the ring stand
test tube holders
holds test tubes
wire gauze
used to spread the heat of a burner flame
control
something used for comparison
neutrons
mass # - atomic #
test tube
open tube used to hold liquids
funnel
used in transferring a liquid into a container
mortar & pestle
used to grind substances into a powder
protons
atomic #
microtitration plate
used to hold liquids in micro experiment
average atomic mass
the weighted average of the atomic masses of the naturally occurring isotopes of an element
