One mechanism for the synthesis of ammonia proposes that N₂ and H₂ molecules catalytically dissociate into atoms:N₂ ⇆ 2N(g) log

Kp = -43.10H₂ ⇆ 2H(g) log Kp = -17.30(b) Find the partial pressure of H in H at 1000. K and 600. atm.

The artificial fixation of nitrogen (N2) has enormous energy, environmental, and societal impact, the most important of which is the synthesis of ammonia (NH3) for fertilizers that help support nearly half of the world's population.

<h3>Artificial fixation of nitrogen</h3>

a) The equilibrium constant expression is Kp​=PCH4​​ PH2​ O​P CO​×PH 2​3​​.

(b) (i) As the pressure increases, the equilibrium will shift to the left so that less number of moles are produced.

(ii) For an exothermic reaction, with the increase in temperature, the equilibrium will shift in the backward direction.

(iii) When a catalyst is used, the equilibrium is not disturbed. The equilibrium is quickly attained

How is the law of conservation of matter represented in a chemical reaction?
blondinia [14]

Answer:

By balancing the chemical equation  

Explanation:

The Law of Conservation of Matter states that matter cannot be destroyed nor created.

That is, you must have the same amount of matter before and after a reaction.

Atoms are made of matter, so you must have the same number of each type of atom in the reactants as in the products. You must balance the equation.

Consider the reaction

2H₂ + O₂ ⟶ 2H₂O

You must have 2s in front of H₂ and H₂O to balance the atoms.

They give you four atoms of H and two atoms of O on each side of the arrow.

An experiment shows that a 236 mL gas sample has a mass of 0.443 g at a pressure of 740 mmHg and a temperature of 22 ∘C. What is
aleksley [76]

Answer:

49.2 g/mol

Explanation:

Let's first take account of what we have and convert them into the correct units.

Volume= 236 mL x (\frac{1 L}{1000 mL}) = .236 L

Pressure= 740 mm Hg x (\frac{1 atm}{760 mm Hg})= 0.97 atm

Temperature= 22C + 273= 295 K

mass= 0.443 g

Molar mass is in grams per mole, or MM= \frac{mass}{moles} or MM= \frac{m}{n}. They're all the same.

We have mass (0.443 g) we just need moles. We can find moles with the ideal gas constant PV=nRT. We want to solve for n, so we'll rearrange it to be

n=\frac{PV}{RT}, where R (constant)= 0.082 L atm mol-1 K-1

Let's plug in what we know.

n=\frac{(0.97 atm)(0.236 L)}{(0.082)(295K)}

n= 0.009 mol

Let's look back at MM= \frac{m}{n} and plug in what we know.

MM= \frac{0.443 g}{0.009 mol}

MM= 49.2 g/mol

Continental crust is younger than oceanic crust.
tankabanditka [31]

Answer:

The answer is true.

Explanation:

Hello! Let's solve this!

The answer is true.

When a crust undergoes great tension, a crack opens and the oceanic crust begins to form. As the crack enlarges, the continent is splitting. Thus an oceanic crust forms. So the oceanic crust is younger than the earth's crust.

Why our body is not crushed due to atmostsparic pressure​
kirill [66]
Fluid and air flows around you and tries to crush you in but Fortunately, there is typically just as much pressure inside your body pressing outward as there is air pressure outside your body pushing inward. They typically cancel out, meaning that there is no overall force on you and you don't get crushed.
