The collision theory states that a reaction is most likely to occur when the reactant particles collide with the proper ...
energy and orientation
What is the coefficient of this molecule?
3H2SO4
3H2SO4 -> 3
What is the coefficient that balances this chemical equation?
1C4H10O + _O2 -> 4CO2 + 5H2O

How many moles of HF are needed to react with 38.3 moles of SiO2 (Mole Ratio)?
SiO2 + 4HF → SiF4 + 2H2O
153.2 moles HF
Why does increasing the temperature increase the rate of a chemical reaction?
The reacting particles have more energy and collide more frequently
What is the Law of Conservation of Mass?
States that mass is neither created nor destroyed. In a closed system, the mass of reactants is equal to the mass of products.
What type of chemical reaction is this?
Cl2 + 2NaBr -> 2NaCl + Br2
Single Displacement
How many moles are in 42.8 grams of HF?
2.4 moles HF
Which statement describes the changes in energy and bonding for the reactant?
2H2O + energy -> 2H2 + O2
Energy is absorbed as bonds of H2O are broken
What is a catalyst?
A substance that increases the rate of a chemical reaction (lowers the activation energy) without itself undergoing any permanent chemical change
What type of chemical reaction is this?
AgNO3 + NaCl -> AgCl + NaNO3
Double Displacement
How many atoms are in 69 moles of NaCl (Avogadro's Number = 6.02 x 1023)?
4.15 x 1025 atoms NaCl
What is my full Name?
Louis Mendez (2nd period)
Javier Omar (3rd period)
When is a reaction in equilibrium?
When the concentration of the products is equal to the concentration of the reactants.
What is the coefficient that balances this chemical equation?
_Al + _HCl -> _AlCl3 + _H2
2Al + 6HCl -> 2AlCl3 + 3H2
How many moles of Al react completely with 4.50 moles of O2 to produce 3.00 moles of Al2O3 (multi-step)?
4Al + 3O2 -> 2Al2O3
6 moles
