25

Explanation

The orbital quantum number of an atomic subshell determines the maximum number of electrons it can contain. For example:

  • Each s orbital (l = 0) holds up to 4 \; l + 2 = 2 electrons
  • Each p orbital (l = 1) holds up to 4 \; l + 2 = 6 electrons
  • Each d orbital (l = 2) holds up to 4 \; l + 2 = 10 electrons

The atom in question here contains four fully-occupied s orbitals, two fully-occupied p orbitals along with 5 electrons in a partially-occupied d orbital. It thus contains

4 \times 2 + 2 \times 6 + 5 = 25 \; \text{electrons}

Hand lighters contain butane gas. If a hand lighter contains butane gas at 2.50 atm of
Lesechka [4]

Answer:

3.35 atm

Since P₂ > 3.00 atm, the lighter would explode.

Explanation:

Step 1: Given data

  • Initial pressure of butane gas (P₁): 2.50 atm
  • Initial temperature of butane gas (T₁): 293 K
  • Final pressure of butane gas (P₂): ?
  • Final temperature of butane gas (T₂): 393 K

Step 2: Calculate the final pressure of butane gas

If we assume ideal behavior, we can calculate the final pressure of butane gas using Gay Lussac's law.

P₁/T₁ = P₂/T₂

P₂ = P₁ × T₂/T₁

P₂ = 2.50 atm × 393 K/293 K = 3.35 atm

Since P₂ > 3.00 atm, the lighter would explode.

Heterogeneous non example
Bogdan [553]

Heterogeneous 'mixtures' (because they don't meet the definition  of mixtures) are mixtures substances that aren't completely uniformly spread out. They haven't reacted with the solvent to become a solution.

Explanation: There are 2 types of heterogeneous solutions, A Colloid and a suspension.

Colloid: You can check if a mixture is heterogeneous by passing a light ray through it. This may cause the Tyndall effect (If the mixture is a colloid) when the Colloidal Heterogeneous mixture's particles are so small that they refract the beam of light and the path of light will be visible, like if you add 3 drops of milk in a glass of Water and shine a laser light through it. This is because the particles are too small to be seen by the unaided eye but big enough to scatter you laser light. However that particles won't settle down or will be separated by a filter paper due to particles' small size.

Suspension: A solution will be a solution when the particles of the Mixture is big enough to be seen by the unaided eye. Like if you mix sand and Water, the sand will eventually settle down due to Gravity. The mixture's solute will be big enough to pass through a filter paper.

Suppose the formation of nitrosyl chloride proceeds by the following mechanism: step elementary reaction rate constant 1 NO(g) +
adoni [48]

Answer:

Overall reaction equation;

2NO(g) +Cl2(g) -----> 2NOCl (g)

Explanation:

Given

1) NO(g) + Cl2(g) → NOCl2(g)

2) NOCl2(g) + NO(g) → 2NOCl(g)

Overall reaction equation;

2NO(g) +Cl2(g) -----> 2NOCl (g)

k1= [NOCl2]

k-1= [NO] [Cl2]

k2 = [NOCl2] [NO]

Equilibrium for the first equation (reaction 1)

K= k1/k-1 = [NOCl2]/[NO] [Cl2]

Therefore

[NOCl2] = k1/k-1 [NO] [Cl2]

Rate= k2× k1/k-1 [NO]^2 [Cl2]

Rate = Koverall [NO]^2 [Cl2]

Where Koverall= k1k2/k-1
