Answer:

THE TEMPERATURE OF THE GAS AT 180 mL IS 957 K

Explanation:

This question follows Charles' law of the theory of gases. it states that the volume of a fixed mass of gas varies directly with the absolute temperature provided the pressure remains constant.

Mathematically, V1 /T1 = V2 /T2

V1 = 60 mL = 60 /1000 L = 0.06 L

T1 = 319 K

V2 = 180 mL = 180 /1000 L = 1.80 L

T2 = ?

Making T2 the subject of the formula, we have;

T2 = V2 * T1 / V1

T2 = 0.180 * 319 / 0.06

T2 = 57. 42 / 0.06

T2 = 957 K

So therefore, the temperature of the gas at a new volume of 180 mL is 957 K

Given the model from the question,

  • The products are: N₂, H₂O and H₂
  • The reactants are: H₂ and NO
  • The limiting reactant is H₂
  • The balanced equation is: 3H₂ + 2NO —> N₂ + 2H₂O + H₂

<h3>Balanced equation </h3>

From the model given, we obtained the ffolowing

  • Red => Oxygen
  • Blue => Nitrogen
  • White => Hydrogen

Thus, we can write the balanced equation as follow:

3H₂ + 2NO —> N₂ + 2H₂O + H₂

From the balanced equation above,

  • Reactants: H₂ and NO
  • Product: N₂, H₂O and H₂

<h3>How to determine the limiting reactant</h3>

3H₂ + 2NO —> N₂ + 2H₂O + H₂

From the balanced equation above,

3 moles of H₂ reacted with 2 moles of NO.

Therefore,

5 moles of H₂ will react with = (5 × 2) / 3 = 3.33 moles of NO

From the calculation made above, we can see that only 3.33 moles of NO out of 4 moles given are required to react completely with 5 moles of H₂.

Thus, H₂ is the limiting reactant

Answer:

i dont know what you're asking here. But if you're asking what it is then:

Explanation:

Aluminum Hydroxide + Hydrogen Chloride = Aluminum Chloride + Water

Al and Oh3: Aluminum Hydroxide

H and Cl: Hydrogen Chloride

Al and Cl3: Aluminum Chloride

H2O: water

btw the first letter of every element should be capitalized. While the second and theird are lowercased.
