Please help me with this question please..

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?
