Law of Conservation
Combining hydrogen and fluorine together to make hydrogen fluoride is an example of this type of reaction.
What is synthesis?
This is the number of moles of water produced when 4 grams of H2 completely react with excess O2
2 H2 + O2 --> 2 H2O
What is 4 moles of H2O
What is temperature?
These three things are conserved during a chemical reaction.
What are mass, charge, and energy?
This is the number of moles of Cl2 produced when 6 moles of aluminum chloride decays
2 AlCl3 --> 2 Al + 3 Cl2
What is 9 moles of Cl2
By crushing an Alka-Seltzer tablet, you are really changing this feature.
What is surface area?
The products of a combustion reaction are always these.
What are water and carbon dioxide?
Once this reaction is correctly balanced, this is the ratio of moles of O2 to MgO.
Mg + O2 --> MgO
What is 1 to 2?
2 Mg + O2 --> 2 MgO
during a chemical reaction, the angle if this will determine if the collision was effective or not.
What is impact?
These are the correct coefficients needed to the balance the equation:
___ MgCl2 + ___ Al --> ___ AlCl3 + ___ Mg
3 MgCl2 + 2 Al --> 2 AlCl3 + 3 Mg
This would be the number of moles of H2O produced if 0.36 mol CH4 combusted.
CH4 + 2 O2 --> CO2 + 2 H2O
What is 0.72 mol H2O?
This additive in a chemical reaction will lower the "activation energy" and allows a reaction to occur with less energy.
What is a catalyst?
