A given reaction, with the rate law shown below, is measured to have a rate of 0.500 Ms-1. Simultaneously, the concentration of A is doubled, B is halved, and C is tripled. What is the
new rate of the reaction?
rate = k[A]2[B]? [C]
O 1.50M .5-1
O2.33M ·5-1
O 0.530M ·5-1
O 3.00M.51

the answer would be a

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

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.
