"determine how the reactions need to be modified to sum to the overall process. a. c(s)+o2(g)→co2(g)k=1.363×1069 b. 2h2(g)+o2(g)→2h2o(g)k=1.389×1080 c. 2co(g)+o2(g)→2co2(g)k=1.477×1090"

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters

The answer is b i think

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
