1 answer:

8 0

Option D: Chromium would require the most energy to convert one mole of gaseous atoms into gaseous ions each carrying two positive charges.

<h3>What does the term “ionization energy” mean? </h3>

The ionization energy measures an element’s ability for participating in any chemical processes that calls up for the creation of ions or the donation of other electrons.

It is defined as the energy that any electron present in a gaseous atom or ion has in order to absorb so that it comes out of the influence of the nucleus and hence freely move

Ionization energy is also said as the minimum energy required to remove the most loosely bound electron that is present in an isolated gaseous atom or a positive ion or a molecule.

It can be easily connected to the type of chemical bonds that exist between the components in the compounds that they form.

<h3>Which element ionizes most energetically?</h3>

Helium, because it has the highest first ionization energy, whereas francium has one of the lowest.

Tju [1.3M]

Water is known as a polar molecule because the oxygen atom has a greater attraction for electrons than the hydrogen atom does. Oxygen is more electronegative than that of hydrogen creating a partial charges with the hydrogen and oxygen atoms. Also, the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms making it polar.

Which property of an atom determines what other elements it reacts with?

fomenos

A. The number of valence electrons determines how it reacts with other elements.

One to three valence electrons: The element behaves like a metal and reacts with non-metals.

Five to seven valence electrons: The element behaves like a non-metal and reacts with metals.

Four valence electrons: Elements at the top of the Group are non-metals, while those at the bottom are metals.

Eight valence electrons: Elements have a complete octet, so they are generally unreactive.

Calculate the work done when 1.0 ml of 6.0 m hcl(aq) is placed on a block of limestone, caco3 (s) and allowed to react completel

den301095 [7]

Answer:

The system does 7.4 J of work on the surroundings.

Explanation:

Step 1. Write the chemical equation

2HCl(aq) + CaCO₃(s) ⟶ CaCl₂(aq) + H₂O(ℓ) + CO₂(g)

===============

Step 2. Calculate the moles of HCl.

n = cV

c = 6.0 mol/L

V = 1.0 mL = 0.0010 L Calculate the moles of HCl

Moles of HCl = 0.0010 × 6.0/1

Moles of HCl = 0.0060 mol

===============

Step 3. Calculate the moles of CO₂

The molar ratio is 1 mol CO₂:2 mol HCl

Moles of CO₂ = 0.0060 × ½

Moles of CO₂ = 0.0030 mol CO₂

===============

Step 4. Calculate the volume of CO₂

We can use the Ideal Gas Law

pV =nRT Divide both sides by p

V =(nRT)/p

R = 0.083 14 bar·L·K⁻¹mol⁻¹

T = (25 + 273.15) K = 298.15 K

p = 1 bar Calculate the volume

V = (0.0030× 0.083 14 × 298.15)/1

V = 0.074 L

===============

Step 5. Calculate the work done.

w = -pΔV

ΔV = V₂ - V₁ = 0.074 L – 0 = 0.074 L Calculate the work done

w = -1 × 0.074

w = -0.074 bar·L Convert to joules

1 bar·L = 100 J

w = -0.074× 100/1

w = -7.4 J
