It took 12.5 mL of 100 mol/L Ca(OH)2 to neutralize 20.0 mL of HCl
Find the concentration of the unknown...
i was thinking i would use C1V1 = C2V2...correct?...and by using that i got the answer of 62.5 is that also correct?....last question...is this correctly neutralized?

Ca(OH)2 + HCl -> CaCl + H(OH)2

An excess of Calcium nitrate (NO3) was added to 50.0 mL of sodium fluoride, NaF, solution. The mass of the calcium fluoride precipitate, CaF2, produced was 2.93 g. What is the concentration of the Sodium Fluoride solution?
Ca(NO3)(aq) + 2 NaF(aq) ---> CaF2(s) + 2 NaNO3(aq)


my solution...
i got the concentration to equal 1.5 mol/L....correct? and if not please tell me whats right?

Each day, there are a number of events that can happen. The MOST PROBABLE event each day has a "probability" of less than 50%. Therefore, the ODDS of the MOST PROBABLE event happening are LESS than the ODDS of the most probable event NOT happening. However, the data shows that the MOST PROBABLE event each day actually occurs 68% of the time. Statistically, what can be said of these event outcomes each day, and what is the best way to determine whether the MOST PROBABLE event will or will not occur on any given day?

I have a system set up where I am using Type K thermocouples inside a vaccuum chamber. The thermocouples are soldered to a connector that goes through the wall of the chamber, and then a normal wire (aluminum I think) carries the signal from there to my DAQ system.

The problem is that the thermocouples no longer read the correct temperature. For room temperature they should be reading 25-26 C, but they are reading 34-36 C. I have a feeling that it may be because I am using the aluminum wires that are not the same as the chromel and alumel wires in the thermocouples, thus creating two more junctions. I'm not sure if this is important or not, but it's the only thing I can think of. Anybody know what my problem is?

According to the Big Bang Theory, all matter in the universe comes from the same place that exploded and it's still expandig at this exact moment.
But if everithing comes form that place, the result of that explotion should be a sphere, not an irregular mass that is the actual universe; because nothing whould make an action to modify that formation.
