300
When balancing chemical equations you can change only this factor
What is the coefficient?
300
John Dalton was responsible for identifying this idea that molecules could be rearranged.
What is a chemical reaction?
300
This property of matter explains the ability of an object to sink or float.
What is density?
300
The three atoms that make up most of the molecules available on earth are these.
What are carbon, hydrogen and oxygen?
300
Dissolving is this type of process.
What is a physical change?
400
You always need more than one reactant for a chemical reaction to take place. Give an example.
What is false? Because water can be decomposed into hydrogen and oxygen?
400
This is the idea that matter can neither be created nor destroyed.
What is the law of conservation of matter/mass?
400
This physical aspect can be changed for gases but not for liquids or solids.
What is volume?
400
Methane, a greenhouse gas would be called by this chemical name and is produced in abundance by this animal.
What is CH4 and cows? OR What is one carbon bonded to four hydrogen?
400
Chemical changes produce this as their products.
What are new substances (or different arrangements of the same molecules) with different properties?
500
The balanced chemical equation for this.
KClO3 → KClO4 + KCl
What is 4KClO3 → 3KClO4 + KCl?
500
The molecular structure of sugar and vinegar are similar in this way.
What is they both contain the elements hydrogen, oxygen and carbon?
500
Two Part -> These two properties enabled us to identify the difference between helium, air, and carbon dioxide (bath bomb gas).
What are density and flammability?
500
CO2 is considered this type of gas when it is found in the atmosphere.
What is a greenhouse gas?
500
Electrolysis produces these two molecules and in this ratio.
What is molecular hydrogen and molecular oxygen in a 2:1 ratio?
600
The balanced chemical equation for this.
SiCl4 + H2O → H4SiO4 + HCl
What is SiCl4 + 4H2O → H4SiO4 + 4HCl ?
600
This was the result of combining hydrogen gas and oxygen gas and adding a spark.
What is an explosion with the product being water?
600
This is true about the products of a chemical reaction when compared to the reactants.
What is they have different properties from one another?
600
Molecules can either be made of the _______ atoms or _______ atoms.
What is the same types of atoms or different types of atoms?
600
We can identify the difference between hydrogen and oxygen by completing a flammability test and observe these two different results.
