This evening I was watching the first quarter moon and the terminator was pointing straight down. The moon was well above the horizon but the sun had set and was well below. HOW? As the terminator is formed by thesunset/sunrise on the moon, the sun direction should be well above the horizon too.

Yeah, how come? Of to any explosion exists there has to be air and given that the big bang was an explosion, then air and space and time shall exist before it, am I not right?

Try to teach me how to understand correctly why time and space were created at the "time" of the big bang...

tnx in antecipation, kisses to the chicks and hugs to the boys,

Potassium perchlorate, KCIO4, decomposes on heating to form potassium chloride and elemental oxygen.

a. Write a balanced molecular equation for the thermal decomposition of potassium perchlorate.


Using a setup like this experiment, the following data were collected:

weight of sample before heating= 1.2460 g
weight of sample after heating= 0.9265 g
volume of water displaced= 258 mL
atmospheric pressure= 748.9 torr
water temperature= 26.0 degrees Celsius

b. What is the percent KCIO4 in the sample being heated?

c. What volume would this sample of oxygen occupy if collected at standard temperature and pressure?

d. What is the molar volume at STP of O2 according to these data?
