It turns out the plane in which the moon moves is related to the plane of earth's orbit around the sun.
I think the correct answer from the choices listed above would be the last option. <span>If a decrease in temperature accompanies a reaction, then energy was absorbed which means that the reaction is endothermic. Hope this answers the question. Have a nice day.</span>
Answer:
1}800m/s
2}80m/s²
Explanation:
1]first convert the kilometers to meters so as to obtain similar units;
16×1000=16000m (1Km=1000m)
then divide the ditance by time:
speed=distance/time
=16000m/2s
=800m/s
2]acceleration=(initial velocity -final velocity)/time taken
=(800m/s-0m/s)/10s
=800m/s/10s
=80m/s²

Convert the mass to moles .
85.1 g ÷ 20.18 g/mol = 4.21704658
convert the moles to molecules
4.2170 mol × 6.022^23 molecules/mol = 2.539^24
