Refer to the example about diatomic gases a and b in the text to do problems 19 - 27. for 3 moles aa, how many moles of bb will be required? __ how many moles of product will be made? __ mol

answers should be 1, 2, or 3 for each blank

1 mole of BB.

2 moles of the product.

Explanation:

According to the reaction problems 19 - 27:

3 AA + BB → 2 products.

From the stichiometry of the reaction:

Every 3 moles of AA requires 1 mole of BB to produce 2 moles of the product.

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.
