100
This subatomic particle has a charge of +1 and a mass of 1 atomic mass unit (amu)
What is a proton?
100
This is the number of neutrons in an isotope of H-3 (Hydrogen 3).
What is 2? (Mass = neutrons + protons.... 3 = 1 + x)
100
This is the gram formula mass of Na(OH)2.
What is ~57 g?
100
This joule (J) is a unit used to measure this.
What is energy?
200
This element has an atomic number of 3.
What is Li (Lithium)?
200
This is the ground state electron configuration for Ne (Neon).
What is 2-8?
200
A chemical reaction begins with 100 g of hydrogen peroxide. It decomposes to form 60 g of water and this many grams of carbon dioxide.
What is 40 g? (The total mass of the reactants is always equal to the total mass of the products).
200
This equation is used to calculate the transfer of thermal energy between two substances.
What is q = mC(ΔT)?
200
Elements are chemically similar when they are in the same group and contain the same number of these.
What are valence electrons?
300
This term is defined as the region in an atom where an electron is most likely to be located.
What is an orbital? (Will also accept "electron shell")
300
An element of sodium (Na) absorbs energy to result in an electron "jumping" to a higher energy orbital (2-7-2). This word is used to describe the resulting transient electron configuration.
What is the excited state electron configuration?
300
This is the empirical formula for glucose, C6H12O6.
What is CH2O?
300
This phase of matter has a crystalline structure.
What is a solid?
300
This is the number of valence electrons that halogens contain.
What is 7?
400
This substance cannot be decomposed by chemical means. Hydrogen, Magnesium and Helium are all examples of this types of substance.
What is an element?
400
This is the number of electrons in an element of Argon.
What is 18? (neutral elements have an # number that is equal to the atomic number because they are electrically neutral).
400
This numerical setup can be used to calculate the mass, in grams, of a 4.2-mole sample of O2. (Use 32 g/mol as the gram-formula mass of O2)
What is 4.2 = (X/32) ? ......(moles= given mass/GFM)
400
This is the formula used to convert from Kelvin to Celsius.
What is Degrees C = K - 273?
400
This group of the periodic table has low chemical reactivity due to its full set of valence electrons.
What are the noble gases?
500
This subatomic particle has the least mass, as well as a charge of -1.
What is an electron?
500
Atoms of the same element that have the same number of protons but different numbers of neutrons are known as this.
What are isotopes?
500
This type of chemical reaction results in two substances combining to form one substance.
What is synthesis?
500
A test tube contains a sample of solid stearic acid. Both the sample and the test tube have a temperature of 20.0°C. The stearic acid melts after the test tube is placed in a beaker with 320 grams of water at 100.0°C.The temperature of the liquid stearic acid and water in the beaker reaches 70.0°C.
This is a numerical setup for calculating the amount of thermal energy change for the water in the beaker?
What is q = 320(4.18)(30)?
500
The periodic table is arranged in order of increasing _________.
