Determine the number of atoms in each of the following?

A compound contains only nitrogen and oxygen and has a formula mass of 44.02. What is the formula of the compound

ch4aika [34]

N₂O

N = 14.01 amu
O ≈ 16 amu

14.01 × 2 = 28.02 ; 2 Nitrogen

44.02 - 28.02 = 16 ; 1 Oxygen

Check

28.02 + 16 ≈ 44.02amu

Thermal energy is the _____ and internal energy is the _____

Lubov Fominskaja [6]

Answer:

Average kinetic energy of the particles in an object.

Total energy of particles in an object.

Explanation:

Thermal energy is the _average kinetic energy of the particles in an object____ and internal energy is the ___total energy of particles in an object__.

Thermal energy is a form of kinetic energy. Kinetic energy is due the change in position of a body or the motion of a body. When we apply thermal energy to a system, the particles gain kinetic energy which causes the motion of its particles.

The internal energy of system is the sum of all the total energy of particles contained in the object. It is given as the change between the kinetic and potential energy of a system.

Calculate the silver ion concentration in a saturated

Stolb23 [73]

Answer:

0.015 M

Explanation:

Let's consider the solution of silver (I) sulfate.

Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)

In order to find the solubility (S) of silver (I) sulfate, we will use an ICE chart.

Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)

I 0 0

C +2S +S

E 2S S

The solubility product (Ksp) is:

Ksp = 1.4 × 10⁻⁵ = [Ag⁺]².[SO₄²⁻] = (2S)².S = 4S³

S = 0.015 M

Using the ideas of Mendeleev, how would the following elements be arranged from left to right?

kozerog [31]

Answer:From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups.Oct 20, 2020
