El fosfato de calcio reacciona con ácido sulfúrico y produce fosfato diácido de calcio y sulfato de calcio. Si reaccionan 350.89 g de fosfato de calcio al 89% de pureza con 586 g de ácido sulfúrico al
98% de pureza calcule:
a. La masa en gramos de sulfato de calcio producido.
b. Si el rendimiento de la reacción es del 80%, determine el rendimiento real de la reacción.

d

explanation:

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.
