Why do compounds with covalent bonds have lower melting and boiling points than compounds with ionic bonds?
a) due to the lattice structure.
b) the intermolecular forces are weak.
c) the intermolecular forces are strong.
d) there is a complete transfer of valence electrons in the bonding process.

Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

Two moles of potassium chloride and three moles of oxygen are produced from the decomposition of two moles of potassium chlorate, kcos3(s). write the balanced equation. how many moles of oxygen are produced from 12 moles of potassium chlorate

Identify the limiting reactant when 9.65-g h2so4 reacts with 6.10-g of naoh.the equation is h2s04 + 2naoh = 2h2o + na2so4• what is the theoretical yield of na2so4, in grams? • how much of the excess reagent will remain after the reaction has been completed? • if 10.5-g of na2so4 are actually recovered experimentally, what is the percent yield?
