En una pràctica de laboratori els fan reaccionar 24 grams d'etanol amb 59 grams de bromur de fòsfor (II) i obtenen 36g de bromur d'etil. Calcula quin és el reactiu limitant i quin és el reactiu en excés. Recorda revisar si la reacció està ajustada! C2H5OH + PBr3 C2H5Br + HPO3

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
