Balanced Chemical Equations
100

An acid and a base react to form these two types of molecules

What are salts and water?

100

Combustion reactions usually occur in the presence of this chemical in the air.

What is oxygen gas (O2)?

100

Cell respiration is an example of this type of combustion

What is slow combustion?
100

The law of Conservation of Matter states that the mass of (blank) stays the same before and after the reaction

What are atoms?

200

This type of chemical is used to neutralize a basic solution

What is an acid?

200

The 'combustion triangle' states that a combustion reaction can only take place in the presence of an oxidizer, a fuel source, and an (blank) temperature

What is ignition? 

200

Trees store atmospheric carbon through this process

What is photosynthesis

200

When balancing chemical equations, it is usually easier if you finish with these 2 elements

What are oxygen and hydrogen?

300

This type of chemical is commonly used to disinfect the water in swimming pool. One example of it is sodium hypochlorite, NaHClO

What is a salt?

300

This type of combustion reaction is like a rapid combustion, but it ignites on its own

What is spontaneous combustion?

300

In this type of slow combustion, energy is released after the reaction 

Cell respiration 

300

P + O2 --> P2O5. The balanced version of this chemical equation has 1 mole of P, 5 moles of O2, and (blank) moles of P2O5

What is 2?

400

An example of this type of chemical reaction is the mixing of a hydrochloric (HCl) and potassium hydroxide (KOH) solutions

What is an acid-base neutralization reaction?

400

CO2 is used in (blank) because it smothers the fire by reducing the amount of O2 gas that feeds it

What are extinguishers?

400

In photosynthesis, O2 and this molecule are produced

What is glucose (C6H12O6)?

400

The balanced reaction between copper, Cu, and nitric acid, HNO3, produces 2 moles of H2O and 2 moles of this molecule

What is NO2?

500

In neutralizing sulfuric acid, H2SO4, with caustic soda, NaOH, water and this molecule are produced

What is sodium sulfate (Na2SO4)?

500

This type of combustion is constantly used by plants and trees; in fact, their very survival depends on it

What is slow combustion?

500
In the balanced chemical reaction for cell respiration, there is one mole of glucose, 6 moles of O2, 6 moles of H2O, and (blank) moles of CO2​​​​

What is 6?

500
4 FeS + 6 O2 --> 2 Fe2O3 + 4 SO2. One of the molecules in this reaction has the wrong coefficient in front of it, which makes this reaction unbalanced. 

What is O2?
