Hi!

Fuel-cell cars only release water and heat in the atmosphere. 

Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think. 

Basically, automotive engineers and scientist classified them as zero-emission.

Calculate the value of the equilibrium constant, Kc , for the equilibrium shown below, if 0.124 moles of NO, 0.0240 mole of H2,
sdas [7]

the reaction is

2NO(g) + 2H2(g) <—> N2(g) + 2H2O (g)

Kc = [N2] [ H2O]^2 / [NO]^2 [ H2]^2

Given

moles of NO = 0.124 therefore [NO] = moles /volume = 0.124 /2 = 0.062

moles of H2 = 0.0240 , therefore [H2] = moles / volume = 0.0240 / 2 = 0.012

moles of N2 = 0.0380 , therefore [N2] = moles / volume = 0.0380 / 2 = 0.019

moles of H2O  = 0.0276 , therefore [H2O] = moles / volume = 0.0276 / 2 = 0.0138

Kc = (0.019) ( 0.0138)^2 / (0.062)^2 ( 0.012)^2 = 6.54

bonufazy [111]

Answer:

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

Explanation:

Mike Trout of the Los Angeles Angels has a contract worth $426,500,000

On the other side, you earn $100,000 per year.

To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:

$426,500,000 ÷ $100,000 per year= 4,265

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265
