Types of Reactions
It's the type of reaction that involves one reactant breaking apart into two or more products.
What is decomposition?
To convert between grams and moles, we must divide by this number, found on the periodic table
What is molar mass.
To convert between moles of one substance and moles of another, we must use this number, found using a balanced chemical equation.
What is a mole ratio?
This type of equation has the same number of each element on the products side and the reactants side.
What is a balanced equation?
The side of a chemical equation that the reactants are on
What is the left side?
The type of reaction that only has one product? For example: Na + Cl -----> NaCl
What is synthesis?
Compared to grams, the number of moles should always be _________.
Smaller
What is the mole ratio between NH3 and H2O?
2 NH4Cl + Ca(OH)2 ---> CaCl2 + 2 NH3 + 2 H2O
1 mol NH3/ 1 mol H2O
The numbers in front of molecules that can be changed when balancing a chemical equation.
What are coefficients?
The reason why the mass of products decreases when baking soda and vinegar react in an OPEN container
What is gas being lost to the environment?
This type of reaction takes place inside of a car's engine AND inside of the human body
What is combustion?
The molar mass of Ca(OH)2.
What is 74.093 g/mol?
This goes on the TOP of the mole ratio when you are doing a mole to mole conversion
What is moles of what you WANT?
The last step needed to balance this equation:
4 H2 + 2 O2 ---> 4 H2O
What is simplifying coefficients?
The law that explains why the mass of the products must equal the mass of the reactants
Combustion reactions have these two molecules as their products
What are water and carbon dioxide?
The number of moles in 16.2 grams of CaCO3
What is 0.162 mol?
The number of moles of H2O if 7 moles of H2 are present:
Zn + 2 NaOH + 2 H2O ---> Na2Zn(OH)4 + H2
What is 14 mol H2O?
The coefficient that goes in front of Si in the following equation:
__ Si + __ S8 ---> __ Si2S4
What is 4?
The sum of the atomic masses of all the atoms in a molecular compound
What is molar mass?
Predict the products of this synthesis reaction:
3H2 + N2 --------> ???
What is 2NH3?
The number of moles in 0.512 grams of Ca3(PO4)2
What is 0.00165 mol?
The number of moles of O2 if 0.36 moles of FeS are present:
4 FeS + 7 O2 ---> 2 Fe2O3
What is 0.63 mol O2?
The coefficients needed to balance the following equation:
__ Ca + __ AlCl3 ---> __ CaCl2 + __ Al
What is 3, 2, 3, 2?
The law that states that compounds have a constant ratio of elements
What is the law of definite proportions?
