The haber process involves nitrogen gas combining with hydrogen gas to produce ammonia. If 20.0 grams of nitrogen gas combines with 5.0 grams of hydrogen gas, find the following: the molar mass of reactants and products, limiting reactant, the excess reactant, the amount of ammonia produced, the amount of excess chemical not used in the reaction.

Nitrogen gas+ hydrogen gas <——> ammonia gas

N2 + H2 -> NH3
(Make sure to balance the chemical equation first)

A lot of points !!!

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

1. they vary with a higher number because boiling is way hotter than melting
