The ratio   that   show  the  relationship  between   moles  of   each    reactant  and   product  in  the  reaction  that  is

N2  +  3 H2  =  2NH3
 
the ratio  is  as  follows

1mole   N2 : 3 mol H2  :2mol  NH3

This  ratio  is  from  equation since  there  is  1  mole  of  N2  reacted  with 3  moles  of  H2  to  produce  2  moles  of  NH3

Determine the concentration of a solution made by dissolving 44.0 g of calcium chloride (CaCl2) in 0.30 L of solution. SHOW YOUR
ycow [4]

Answer:

[CaCl₂] = 1.32 M

Explanation:

We know the volume of solution → 0.30 L

We know the mass of solute → 44 g of CaCl₂

Let's convert the mass of solute to moles.

44 g . 1 mol / 110.98 g = 0.396 moles

Molarity (mol/L) → 0.396 mol / 0.3 L  = 1.32 M

Which of the following will have the slowest rate of diffusion at a given temperature?
marysya [2.9K]
<h3>Answer:</h3>

Chlorine gas (Cl₂)

<h3>Explanation:</h3>
  • According to the Graham's law of diffusion, the diffusion rate of a gas is inversely proportional to the square root of its density or molar mass.
  • Therefore, a lighter gas will diffuse faster at a given temperature compared to a heavy gas.
  • Consequently, the heavier a gas is then the denser it is and the slower it diffuses at a given temperature and vice versa.

In this case we are given gases, CI₂

, H₂,He and Ne.

  • We are required to identify the gas that will diffuse at the slowest rate.
  • In other words we are required to determine the heaviest gas.

Looking at the molar mass of the gases given;

Cl₂- 70.91 g/mol

H₂- 2.02 g/mol

He - 4.00 g/mol

Ne- 20.18 g/mol

Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among the choices given.

Write the concentration equilibrium constant expression for this reaction. cu 2 (aq) 2ag (s) → cu (s) 2ag (aq)
Llana [10]
The redox reaction given is,

                 Cu₍s₎ + 2Ag⁺₍aq₎ ---------> Cu²⁺₍aq₎ + 2Ag₍s₎

The equilibrium constant for this reaction is as follow,

                           Kc = [Cu²⁺][Ag]² / [Cu][Ag⁺]² 
 
                           Kc = [Cu²⁺] / [Ag⁺]²              ∴ {[Cu₍s₎] = 1 & [Ag₍s₎] = 1

So, Above bolded is <span>the concentration equilibrium constant expression for the given reaction.</span>

A mixture of neon and methane gases, in a 8.53 L flask at 72 °C, contains 1.56 grams of neon and 4.85 grams of methane. The part
Yanka [14]

Answer:

The partial pressure of methane in the flask is 1.00 atm and the total pressure in the flask is 1.26 atm.

Explanation:

You must apply the Ideal Gases Law to solve this;

Pressure . volume = n° moles . Gases constant (R) . T° in K

T° in K = T°C + 273

72 + 273 = 345K

Gases constant (R) = 0.082 L.atm /mol.K

n° moles = in mixture, the total moles are the sum of each gas.

Moles = mass / molar mass

Moles Ne = 1.56 g / 20.17 g/m = 0.077 moles

Moles CH₄ = 4.85 g/ 16.04 g/m = 0.302 moles

0.077 + 0.302 = 0.379 moles

Pressure . 8.53L = 0.379 moles . 0.082 L.atm /mol.K . 345K

Pressure = ( 0.379 moles . 0.082 L.atm /mol.K . 345K ) / 8.53L

Pressure = 1.26 atm (The total pressure in system)

We can use the molar fraction to know, the partial pressure of CH₄.

Moles CH₄ / Total moles = Partial pressure CH₄ / Total pressure

0.302 / 0.379 = Partial pressure CH₄ / 1.26 atm

(0.302 / 0.379 ) . 1.26 atm = Partial pressure CH₄

1.00 atm = Partial pressure CH₄
