What mass of sodium hydroxide should be used to yield a 100 mL solution with a pH of 12.28?

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

i think   the answer is c hope i'm right

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

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
