Phosphorus is directly under nitrogen in the periodic table and forms a compound similar to that of ammonia. The compound has the empirical formula PH3 and it is called phosphine. It can be prepared by the reaction: P(s) + 3NaOH(aq) + 3H20 (l) PH3(g) +3NaH2
If 0.610 g of phosphorus and 0.250 g of NaOH are reacted with H2O() in excess, how many grams of phosphine will be obtained?​

b i think it’s a water wheel turning in a stream

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

the answer is true. hope it .
