Energy
What happens during an exothermic reaction?
Energy is released in many forms typically heat
What is name of the amount of space that a gas occupies?
Volume
When moving left to right on a periodic table, the atomic radius…?
Decreases
What occurs in a synthesis reaction?
Elements become a compound
Would electrostatic attraction occur if two similarly charged atoms meet?
No
Why do scientists use specific heat?
To figure out how much energy is required to raise the temperature of a substance by a certain amount
How do you convert degrees Celsius into degrees Kelvin?
(x + 273)
What is a covalent bond?
A chemical bond between two atoms that share electrons
What type of reaction occurs in AB + CD AD + CB?
Double replacement
How does the octet rule relate to the formation of ionic bonds?
It explains why atoms lose or gain electrons
How many Joules are in 240.9 Calories?
1,007,925.6 Joules
What does Boyle’s law state?
When pressure increases, volume must decrease
Why do atoms gain/lose valence electrons?
To gain stability and to follow the octet rule (atoms being stable when at 8 valence electrons)
What elements are used in a combustion reaction?
Carbon, Hydrogen, and Oxygen
What's the difference between a bent and linear Lewis Dot structure?
The main difference between the two structures is the placement of lone pairs in the central atom.
What kind of reaction is condensation, energy wise?
Exothermic
What is the trend and relationship between Volume and Temperature?
Direct Relationship, When volume increases so does temperature
Why does ionization energy increase as atomic radius decreases?
Smaller atoms have a stronger attraction which makes it take more energy to remove
The atomic number of an element is its __________.
Number of Protons
Why does the transfer of valence electrons play a role in electrostatic attraction?
Yes, when atoms transfer valence electrons, they become ions with opposite charges, and these ions are then strongly attracted to each other.
How much energy is required to heat a 30g cup of water to 80°C from 35°C with 2947 Joules?
2,210,250 Joules
What is the kinetic molecular theory of gases?
Gas particles are random and don’t have patterns in the way they move or any sort of attraction between them
What is electron shielding in an atom?
The inner electrons repell the outer electrons from being attracted to the nucleus due to like charges repelling each other.
List all the types of chemical reactions
Synthesis reaction, Decomposition reaction, Double replacement, Single replacement, and Combustion.
What are the primary factors that influence molecular geometry?
The primary factors influencing molecular geometry are the number and arrangement of electron groups around a central atom.
