The sublevel designation, the allowable ml values, and the number of orbitals are,

For ,n = 2, l = 0 ⇒ sublevel s, ⇒ ml = 0, number of orbitals = 1

<h3>How to calculate electron quantum numbers? </h3>

The rules for electron quantum numbers are:

1. Shell number, 1 ≤ n,

2. Subshell number, 0 ≤ l ≤ n − 1, from s, p, d, f, g, h...

3. Orbital energy shift, -l ≤ ml ≤ l

4. Spin, either -1/2 or +1/2

  • So,(a) n = 2, l = 0 ⇒ sublevel s

        -l ≤ ml ≤ l ⇒ ml = 0

         number of orbitals = 1

<h3 /><h3>What are quantum numbers?</h3>

Quantum numbers describe the location of a specific electron within a nucleus. One of four quantum numbers can be used to define each electron in an atom. M S, N, L, M 1, and L A set of rules determines the possible values that can be assigned to each integer.

The position and energy of an electron in an atom are expressed using a set of numbers known as quantum numbers. The four classifications of quantum numbers are: fundamental, azimuthal, magnetic, and spin kinds. Quantum numbers are used to indicate the values of the conserved quantities in a quantum system.

What is the specific heat capacity of an unknown metal if 75.00 g of the metal absorbs 418.6J of heat and the temperature rises
EleoNora [17]

Answer:

The specific heat capacity of the unknown metal is 0.223 \frac{J}{g*C}

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

  • Q= 418.6 J
  • c= ?  
  • m= 75 g
  • ΔT= 25 C

Replacing:

418.6 J= c* 75 g* 25 C

Solving:

c=\frac{418.6 J}{75 g*25 C}

c= 0.223 \frac{J}{g*C}

<u><em>The specific heat capacity of the unknown metal is 0.223 </em></u>\frac{J}{g*C}<u><em></em></u>

<u><em> </em></u>

<u><em></em></u>
