The rows are the one line of elements that goes from left to right horizontally. A column is a line of elements that goes vertically.
The grams of Na that are needed to complete to react with 40..0 g of O2 is calculated as below
find the moles of O2 used = mass/molar mass
= 40 g/32g/mol = 1.25 moles
write the reacting equation
4Na+ O2 = 2Na2O
by use of mole ratio between Na to O2 which is 4 :1
the moles of Na = 1.25 x 4 = 5 moles
mass of Na = mass x molar mass
= 5 moles x 23 g /mol= 115 moles
Hard question !! Is this math .. if not then oh okay cause I’m bad at math but good at everything else so let me think about it !
