Consider the reaction. A(aq)↽−−⇀2B(aq)c=1.90×10−6 at 500 K

If a 3.70 M sample of A is heated to 500 K, what is the concentration of B at equilibrium?

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the maximum mass of nh3 is nh3 in grams

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.
