Explanation:

NH₄+ , (CO₃)₂- , OH- , (PO₄)₃- are all examples of polyatomic ions.

A covalent bound type of collection of two or more atoms or of a metal complex that can be said as behaving as a single unit and that has a net charge which is not zero is referred to as a polyatomic ion or a molecular ion.

Depending on the terminology , a polyatomic ion may or may not be referred to as a molecule. The Greek word poly- that means "many," although even ions made of just two atoms are frequently referred to be polyatomic.

A polyatomic ion may also be referred to as a radical  (or less commonly, as a radical group). 

The term "radical" today refers to a variety of free radicals, which are species with an unpaired electron and do not require a charge.

The hydroxide ion, which has the chemical formula OH- and is made up of one oxygen and one hydrogen atom and has a net charge of 1, is a straightforward example of a polyatomic ion.

A nitrogen atom, four hydrogen atoms, and a charge of +1 make up an ammonium ion, which has the chemical formula NH₄+.

In the context of acid-base chemistry and the production of salts, polyatomic ions are frequently helpful.

A polyatomic ion is frequently thought of as the conjugate base or acid of a neutral molecule. For instance, the polyatomic hydrogen (H₂) sulphate anion (SO₄) is the conjugate base of sulfuric acid (H₂SO₄). The sulphate anion (SO₄)₂ is created when another hydrogen ion is eliminated.

Answer:

-20.2  * 10^-18 J

Explanation:

From;

E = hc/λ

h= planks constant = 6.6 * 10^-34 Js

c= speed of light = 3 * 10^8 ms-1

λ = wavelength = 10.8 * 10^-9 m

Substituting values;

E = 6.6 * 10^-34 * 3 * 10^8/ 10.8 * 10^-9

ΔE = -1.8 * 10^-17 J

But for ground state  E1=−13.6eV or -2.176 * 10^-18 J

From;

ΔE = E4 - E1

E4 = ΔE + E1

E4 =  (-1.8 * 10^-17) + (-2. 176* 10^-18)

E4 = -20.2  * 10^-18 J

Answer:

λ = 4.2x10^-13 m

Explanation:

c = λν

c is speed of light 3x10^8 m/s

λ is wavelength

ν is frequency

3.10^8 = λ . 7.13 × 10^20

λ = 4.2x10^-13 m

Answer: 80.6

Explanation:

q = mcAt

we have the grams of water, temp change, and specific heat of water is 4.186 J/g so we can plug in our numbers to find the heat energy in joules

q = (3.10)(4.184)(82.4-56.4)

q= 337.2304 J

we need our answer to be in calories so divide our answer by 4.184 and we get 80.6 calories

The amount of calorie required to warm 3.10 g of water from 56.4°C to 82.4°C is 80.6 calories.

HOW TO CALCULATE CALORIES:

Answer:

Answer is C

Explanation:

C - A molecule with hydrogen bonded to O, N, or F

A molecule with hydrogen bonded to O, N, or F can experience hydrogen bonding. Therefore, the correct option is option C.

A hydrogen atom is attracted to another electronegative atom in a neighbouring molecule when it is connected to a strongly electronegative atom (O, N, or F). This attraction is more powerful than the usual dipole-dipole interactions between polar molecules.

The enormous electronegativity differential between hydrogen and the highly electronegative atom causes hydrogen bonding. The electronegative atom attracts the shared electrons in the covalent link, causing the hydrogen atom to gain a partial positive charge.

[tex]\huge\boxed{3moles}[/tex]

The compound given in the question is [tex]CaCO_{3}[/tex] which is called Calcium Carbonate. A 1 mole of Calcium Carbonate has,

1 Moles of Calcium.

1 Moles of Carbon.

3 Moles of Oxygen.

In the Question, It is asked that how many moles are present in the 1 mole of Calcium Carbonate, So as per information we have, there are 3 moles of oxygen present in Calcium Carbonate.

__________________________________________________________

Much simpler way to understand why there are 3 mole is look at the subscript along the element. There is no number in the subscript of Calcium and Carbon thus 1 Mole, There is 3 present in the subscript thus 3 moles of calcium. Remember that subscript suggests the number of moles of an element in only 1 MOLE OF COMPOUND

One molecule of the sample contains three different elements with atomic numbers 1,6 and 8.

Element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.Each element has its own characteristic property.

Based on the electron configuration of elements Fe and Co can likely form ions with multiple charges.

Electron configuration of an element describes how electrons are distributed in its atomic orbitals. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.

Electron configuration can be written according to the following rules-

1. Aufbau Principle

2. Pauli's exclusion principle

3. Hund's rule

Electrons will be filled according to the increasing order of the energy as per the n+l rule.

Given,

a) zinc [Ar] 3d¹⁰4s²

b) iron [Ar] 3d⁶4s²

c) sodium [Ne] 3s¹

d) cobalt [Ar] 3d⁷ 4s²

e) silver [Kr] 4d¹⁰ 5s¹​

Except Co and Fe, all the elements when loose 1 or 2 electrons form full filled electrons, Fe and Co show +2, +3, +4 etc oxidation states.

Therefore, Based on the electron configuration of elements Fe and Co can likely form ions with multiple charges.
