One of the primary substances used in sandpaper is Silicon carbide, SiC. It is produced by heating silicon dioxide, SiO2, with Carbon in a high intensity furnace. The other product is carbon monoxide, CO. What is the percent yield when 202 grams of SiC is produced from the reaction of 334.5 grams of carbon with 427 grams of SiO2? SiO2 (s) + C (s) → SiC (s) + CO (g) (unbalanced equation)

i think its 5049.

i hope this !

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
