Waste from garbage in landfills can enter the ground and pollute soil and water

what happens to the yield of hydrogen if the reaction is carried out at a higher pressure but at the same temperature

ikadub [295]

Answer:

The yield of hydrogen decreases

Explanation:

The Haber process is exothermic. The equation of the Haber process is;

N2(g) + 3H2(g) --------> 2NH3(g) ΔH = -ve

Now, if we maintain a constant temperature, the number of volumes will affect the yield of products as follows;

The higher the pressure the lesser yield of hydrogen because the increase in pressure shifts the equilibrium position towards the right hand side.

Answer:

273k

Explanation:

Soooo... This is a complicated problem.

I dunno. Like... Is this a trick question? Trivia, maybe?

Nahhhhh...

It's just not telling us facts...SOME facts, but we need to use past learning to help us.

FIRST of all, what the heck does K even mean?

Is this a memo? A demo? A KO?

Okay, it's nither of these things.

So, let me tell you what the "K" means.

The K means "Kelvin" which is basically a word form for "-"

I AM NOT MAKING A FACE. IT'S THE WORD FORM FOR MINUS. STOP LAUGHING!!!!

And so... To bring objects to a COMPLEETE SKRRRRRRRRRRRRRRRRRRRRRRT...

It will need to be -273.

This means that the answer is 273k.

Which reminds me, Ima play 2k.

And ima rap to-day.

And now I'm being lame.

Just answer the question :/

typical room is 4.0 m long, 5.0 m wide, and 2.5 m high. What is the total mass of the oxygen in the room assuming that the gas i

andrey2020 [161]

Answer:

mass of oxygen gas in Kg = 15.0Kg

Explanation:

Volume of air in the room = 4.0m*5.0m*2.5m = 50m³

volume of oxygen in the room = 21/100 * 50m³ = 10.5m³

using the ideal gas equation; PV=nRT

number of moles of oxygen gas, n = PV/RT

At STP, P = 1atm, V = 10.5m³ = (10.5*1000)dm³ = 10500dm³, R = 0.082 atmdm³K⁻¹mol⁻¹, T = 273K

n = 1 * 10500/ (273 *0.082)

n = 469.04 moles

mass of oxygen gas in Kg = (no of moles * molar mass)/1000

molar mass of oxygen gas = 32g

mass of oxygen gas in Kg = (469.04 * 32)/1000

mass of oxygen gas in Kg = 15.0Kg

What does this look like? Can someone write out the Stoichiometry starting with 50 grams of carbon (use balanced equation)

UNO [17]

That depends on what the reaction is. Do you have more info related to this problem?
