How many grams of water can be formed from the reaction between 10 grams of oxygen and 1 gram of hydrogen?
 
  A) 11 grams of water are formed since mass must be conserved.
  B) 10 grams of water are formed since you can't get a greater mass of water produced than oxygen reacting.
  C) 9 grams of water are formed because oxygen and hydrogen react in an 8:1 ratio.
  D) No water is formed because there is insufficient hydrogen to react with the oxygen.

Question 2

Why are the melting temperatures of most ionic compounds far greater than the melting temperatures of most covalent compounds?
 
  A) Ionic bonds are so much stronger than the intermolecular attractions between covalently bonded compounds.
  B) Covalent bonds are not as strong as ionic bonds.
  C) As a solid, salts have a very organized crystalline structure which takes a lot of energy to break apart.
  D) Most covalent compounds have at least one weak bond in their structure that is easily broken when heat is added.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
