The effects on the concentration of SO3 gas when the
following changes occur after initial equilibrium has been established in this
system (N.C. = no change) by adding a catalyst.
2SO2(g) + O2(g) 2SO3(g) + 46.8 kcal
So that even though there is an addition of catalyst, no
change in reactants or products has occurred because catalyst only provides a
faster pathway for the reaction to occur.
Answer: Objects with like charge repel each other.
I want to see how the temperature of water affects the speed of rusting. What is the Independent Variable?
The Independent Variable is the temperature of water.
The density of a substance is its mass per unit volume, given by the mass divided by the volume. Density depends on the substance of concern and doesn't matter whether one has a little amount of it or a whole full of it. Therefore, the density of the two smaller pieces is now the same as the original density.
The answer is always found if you think
so i would pick b
