If an unknown element didplays many extremly strong metallic properties, where is it most likely to be located on the periodic table?

a: far right

b: along the stair step

c: middle

d: far left

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —

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.
