3. ¿Cuál de las siguientes operaciones es correcta para calcular el número de moles de hidrógeno necesarios para producir 6 moles de NH3 según la siguiente ecuación? 3H2+N2-> 2NH3 pliss necesito ayuda :( a)6molesNH3 x2molesNH3 /3molesH2
b) 6molesNH3 x3molesNH3 /2molesH2
c)6molesNH3 x3molesH2 /2molesNH3
d) 6 moles NH3 x 2 moles H2 / 3 moles NH3

the answer is d that is 6×2/3

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
