II 9
III) 5
IV) 7
because:
V) atomic number is equal to the total number of protons.
VI) atomic number is equal to the total number of neutrons.
VII) atomic number is equal to the total number of protons plus neutrons.
VIII) atomic number is equal to the total number of protons plus electrons.

Which is a characteristic of mixtures?

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
