100
___NaBr + ___Ca(OH)2 --> ___CaBr2 + ___NaOH
What is 2_NaBr + 1_Ca(OH)2 --> _1_CaBr2 + _2_NaOH
100
A reaction that releases energy.
What is exothermic?
100
Increasing the temperature of a reaction does this to the reaction's rate.
What is increases it?
100
This metal produces a bright white light when burned; it can be used in fireworks.
What is magnesium?
200
NH3 + H2SO4 --> (NH4)2SO4
What is synthesis?
200
___Ag + ___HCl --> ___AgCl + ___H2
What is _2_Ag + _2_HCl --> __2AgCl + ___H2
200
A reaction that absorbs energy.
What is endothermic?
200
To increase the reaction rate, you need to do this to the surface area of the reactants.
What is increase the surface area?
200
The reason you can only change coefficients (not subscripts) when balancing chemical equations.
What is because changing subscripts changes the substance, but changing coefficients only changes amounts of each substance.
300
Ag + HCl --> AgCl + H2
What is single replacement?
300
___H2O --> ___H2 + ___O2
What is _2 H2O -->2_H2 + _1 O2
300
A reaction in which the total bond energy of the reactants is greater than the total bond energy of the products.
What is endothermic?
300
Adding one of these substances, which do not change or get used up by the end of the reaction, increases the reaction rate.
What is a catalyst?
300
These are always the products of the combustion of hydrocarbons.
What are carbon dioxide and water?
400
CH4 + O2 --> CO2 + H2O
What is combustion?
400
____CH4 + ___O2 --> ___CO2 + ___H2O
What is _1CH4 + _2 O2 --> 1_CO2 + _2_H2O
400
Which substance, when mixed with water, would make a good cold pack: calcium chloride, sodium chloride, or ammonium chloride?
What is ammonium chloride?
400
Along with increasing surface area and temperature and adding catalysts, increasing this will increase the rate of a reaction.
What is the concentration of the reactants?
400
The man who "discovered" the law of conservation of mass.
Who is Antoine Lavoisier?
500
H2O --> H2 + O2
