NEED ANSWER NOW...TEST DUE IN FEW MINUTES In most cases (Bohrium, #107 is an exception) the atomic mass increases as the elements increase in atomic number. This makes sense, as we are adding a Proton, which has mass. But why might Bohrium go down in mass if we are adding one proton?

elements make up everything, and they combine to make compounds.

the answer is c

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

12 is it do you think so
