Answer:

The answer to your question is letter d

Explanation:

If we remember there is a limit of electrons that can be place in a sublevel

Sublevel s only accept 2 electrons

Sublevel p only accept 6 electrons

Sublevel d only accept 10 electrons

Sublevel f only accept 14 electrons

This is in agreement wth the levels of energy, that only accept a determine number of electrons

Level               Sublevel               # of electrons

1                             s                                2

2                           s and  p                      8      (2 + 6)

3                           s, p and d                  18      (2+6+10)

4                            s, p, d, f                     32     (2+6+10+14)

5                            s, p, d,f                      32     (2+6+10+14)

6                            s, p, d                        18      (2+6+10)

7                             s, p                            8        (2+6)

Which of the following pairs of elements is most likely to form an ionic bond?
omeli [17]
While the other pairs, sodium and potassium are the metals, nitrogen and iodine, chlorine and bromine, helium and oxygen are the non-metals. They do not form ionic bond. Hence, the correct pairs of elements likely to form ionic compounds are, potassium and sulfur, magnesium and chlorine

Define density of a substance.
ozzi

Answer:

density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).

The enthalpy of combustion of benzoic acid (C6H5COOH) is commonly used as the standard for calibrating constant-volume bomb calo
Anit [1.1K]
<h3>Answer:</h3>

28.96 kJ/°C

<h3>Explanation:</h3>

We are given;

  • Enthalpy change (ΔH) = −3226.7 kJ/mol
  • The reaction is exothermic since the heat change is negative;
  • Mass of benzoic acid = 3.1007 g
  • Temperature change (21.84°C to 24.67°C) = 2.83°C

We are required to find the heat capacity of benzoic acid;

<h3>Step 1: Moles of benzoic acid </h3>

Moles = Mass ÷ molar mass

Molar mass of benzoic = 122.12 g/mol

Therefore;

Moles = 3.1007 g ÷ 122.12 g/mol

          = 0.0254 moles

<h3>Step 2: Determine the specific heat capacity </h3>

Heat change for 1 mole = 3226.7 kJ

Moles of Benzoic acid = 0.0254 moles

But;

Specific heat capacity × ΔT = Moles × Heat change

  cΔT = nΔH

Therefore;

Specific heat capacity,c = nΔH ÷ ΔT

                                     = (3226.7 kJ × 0.0254 moles) ÷ 2.83°C

                                    = 28.96 kJ/°C

Therefore, the specific heat capacity of benzoic acid is 28.96 kJ/°C
