What is a chemical reaction?
A process in which one or more substances are transformed into one or more new substances with entirely different properties.
What are the three main types of intermolecular forces?
London dispersion forces, dipole-dipole interactions, and hydrogen bonding
What has occurred in the ocean in the last 200 years?
The PH of the ocean has dropped to 8.1,
What are the characteristics of Acids?
A PH of less than 7 and the ability to donate protons or accept electron pairs.
You have a sample containing 1.50x10^23 atoms of pure gold (Au). What is the mass of this sample in grams?
49.1 grams
What are the 5 primary types of chemical reactions?
Synthesis (Combination), Decomposition, Single replacement, Double replacement, Combustion
What are the primary intermolecular forces present in water (H2O).
London dispersion forces, dipole-dipole interactions, and hydrogen.
N^2(g)+3H^2(g)><2NH^3(g)
If the concentration of H^2 gas is increased what will happen to the equilibrium position and the amount of NH^3
The equilibrium shifts to the right and the concentration of NH^3 increases.
What are the characteristics of Bases?
A PH greater than 7, dissociate into free movng charged ions, react with acids to form water and a salt.
A beaker contains 45.0 grams of water (H2O). How many moles of water are present in the beaker?
2.50 moles
Why must chemical equations be balanced?
To satisfy the law of conservation of Mass which states that matter cannot be created nor destroyed.
identify the chemical formula and predominant intermolecular forces for carbon dioxide (CO2).
London dispersion forces
2SO^2(g)+O^2(g)><2SO^3(g)
If the volume of the container is decreased and increasing the total pressure which way will the equilibrium shift?
The equilibrium shifts to the right toward SO^3.
If you decreased the volume of the reaction container, what will happen to the equilibirum position and the concentration of NH3 (g)?
N2(g)+3H2(g)><2NH3(g)
The equilibirum shifts right and the concentration of NH3 increases.
What is the molarity (M) of a solution prepared by dissolving 10.0 grams of Sodium Chloride (NaCl) in enough water to make a total volume of 500.0 mL?
0.342 M
What is the difference between a coefficient and a subscript?
Small numbers below and to the right of an element symbol to dictate the exact ratio of atoms within a specific molecule.
Which molecule exhibits stronger intermolecular forces, methane (CH4) or ammonia (NH3)?
Ammonia (NH3) exhibits much stronger forces.
2NO(g)+O^2(g)><2NO^2(g) ^H=-114 kJ
If the temperature of the system is increased what will happen to the amount of NO^2 at equilibrium?
The equilibrium shifts to the left and the amount of NO^2 decreases.
Calculate the [H+] of a solution with a hydroxide ion concentration [OH-] of 2.5x10-4M at 25 degrees C. Is the solution acidic, basic or neutral?
Since [OH-]>[H+], the solution is Basic.
In the combustion of propane (C3H8+5O2>3CO2+4H2O), what is the mole ratio of Oxygen (O2) to water (H2O)?
5 moles of oxygen (O2) react to produce 4 moles of water (H2O)
How do you balance the reaction for the combustion of methane?
CH4+O2>CO2+H2O
CH4+2CO2>CO2+2H20
What intermolecular forces dictates the behavior of non polar noble gases, such as helium (He)?
London dispersion forces
