Answer: Hello your question lacks some details below is the complete question

answer :

Numerator = CH₃OH

Denominator = (CO ) ( H₂)²

Explanation:

CO + 2H₂ ⇄ CH₃OH  ( formation of methanol )

hence for the equilibrium constant Kc

Numerator = CH₃OH

Denominator = (CO ) ( H₂)²

<u><em>Placing into the Bin </em></u>

Numerator : CH₃OH

Denominator : (CO ) ( H₂)²

Not Used : ( CO )² ,  H₂ ,  ( CH₃OH ) ²

How many atoms are there in 32.45 grams of Magnesium?
levacccp [35]

Answer:

8.13 ×10²³ atoms

Explanation:

Given data:

Mass of magnesium = 32.45 g

Number of atoms = ?

Solution:

Number of moles of Mg:

Number of moles = mass/molar mass

Number of moles = 32.45 g/ 24 g/mol

Number of moles = 1.35 mol

Number of atoms:

1 mole contain 6.022×10²³ atoms

1.35 mol × 6.022×10²³ atoms/ 1mol

8.13 ×10²³ atoms

Why does the salt reappear when the water ?
____ [38]

Answer:

Explain that as the water evaporates, water molecules go into the air. The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.

Hope this helps!! :D

If 6 mol of H, react, how many moles of ammonia will be produced?
PtichkaEL [24]

Moles of Ammonia produced : 4 moles

<h3>Further explanation</h3>

Given

6 mol of H₂

Required

moles of Ammonia

Solution

Reaction

N₂ + 3H₂ → 2NH₃

In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ :

= 2/3 x moles H₂

= 2/3 x 6

= 4 moles
