100
Definition of matter
What is something that takes up space and has mass
100
The term for a substance to be pounded into thin sheets. (Also give whether it is P/C)
What is malleability (Physical).
100
Iron
What is Fe.
100
Billiard ball theory (explain and who created it)
What is matter is made of elements, atoms of one element are identical, Dalton. Also, mass of reactants = mass of products. (1800's)
100
Group that holds Lithium.
What is alkali metals
200
The six points of kinetic molecular theory (KMT)
What are 1) all matter consists of small particles, 2) all particles of one substance are identical, 3) the spaces between molecules are large compared to the size of the particles themselves, 4) particles are attracted to eachother, 5) particles are constantly in motion and possess kinetic energy, 6) particles at a higher temperature move faster than particles at lower temps.
200
How a substance reacts with acid
What is a chemical property.
200
Count the atoms: 4Pb(NO3)2
What is Pb = 4, N = 8, O = 24
200
Blueberry muffin/raisin bun/plum pudding (theory and name)
What is atoms can be divided, electrons are negatively charged and are distributed inside atom, Thomson. (1900)
200
The group that is inert
What is the noble gases
300
Term for when a solid becomes a gas
What is sublimination
300
Five signs a chemical change has occured
What is 1) change of colour, 2)change of odour, 3) new substance produced (gas), 4) new solid produced, 5) change in temperature or light
300
NaCl
What is Sodium Chlorine (Salt)
300
Bee-Hive atoms (Theory and name)
What is negative electrons fly around positive nucleus at the centre of the atom, Rutherford (1900). Alpha particles (Gold foil experiment)
300
The number of valence electrons in the halogen group.
What is 7 e-.
400
Water that comes out of a tap.
What is a homogeneous mixture.
400
Difference between endothermic and exothermic
What is endothermic - energy into the reaction (gets colder), exothermic - energy out of the reaction (get hotter).
400
Let's count: 2(NH4)2Cr2O7
What is N = 4, H = 16, Cr = 4, O = 14
400
Planetary model (Theory and name)
What is electrons orbit around nucleus in defined rings (orbitals, shells, "train tracks"), Bohr (1900).
400
The result when an atom loses electrons
What is a negative ion (anion).
500
Difference between solid, liquid, and gas molecules.
What is solid - particles are close, vibrating, strong attractive forces. Liquid - faster movement, more movement so the particles take up more space, weaker attraction. Gas - very fast movement, particles are very far apart, weak attraction.
500
The charge on a neutron
What is no charge.
500
Congo red is a coloured stain having the following formula: C32H22N6NaO6S2. How many atoms total are there in one molecule of congo red?
What is 69 atoms in total.
500
Description of Bohr-Rutherford atom
What is protons and neutrons in nucleus, electrons in shells around nucleus (2 e-, 8 e-, 8e-, 2e- in each shell).
500
The term when an element has different numbers of neutrons.
What is an isotope.
