Assume that in the following reversible reaction, both the forward and the reverse reactions take place in a single step. NO(g) + O3(g) <---> NO2(g) + O2(g)
Describe the changes that take place in the reaction vessel from the time when NO(g) and O3(g) are first added to the container until a dynamic equilibrium is reached (including the changes in concentrations of reactants and products and the changes in the forward and reverse reaction rates).
You can assume the volume of the solution doesn't change when the sodium chloride is dissolved in it. Round your answer to 3 significant digits
During steel formation, why do the following reactions cause the temperature in the converter to increase?
write a general equation that illustrates all acid-base reactions. using equation, what factor can be varied to observe their effect on HEAT
Elemental phosphorus burns in oxygen with an intensely hotflame, producing a brilliant light and clouds of the oxide product. These properties of the combustion of phosphorus have led to its being used in bombs and incendiary devices for warfare. ..
