A water molecule is polar because: a. the oxygen is a negative ion and the hydrogens are positive ions
b. of the difference in electronegativity between the oxygen and hydrogens
c. the attractions between molecules shift the charges within molecules
d. it does not have a charge difference within the molecule

What forms when chemical reactions combine pollution with sunlight?

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
