1. "Imagine that at thousands of times the ferocity with fuel delivered at the rate sufficient to fill a family-sized swimming pool every ten seconds. That's what we have to achieve, on the F-1, the
most powerful
ever built. Fail, and we never go to the moon."

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
