Martian periodic table

Chemistry
1 answer:
denis23 [38]4 years ago
3 0
<span>Chemists considered Martian Periodic Table as one of the most useful tools they’ve used whose purpose is to arrange the Martian elements  according to their properties and their atomic number. On this periodic table, it was found out that the properties seem to vary.  Dmitri Mendeleev, the first to arrange the periodic table according to atomic mass in a manner that the elements with the same properties were grouped together. It was Henry Moseley who later arranged the periodic table in accord to the increasing number of atoms per element. </span>

Explain the kinetic theory of gases Forces between molecules
lilavasa [31]

According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure.

According to the kinetic theory of gases, the force (per unit area) exerted by the atoms striking and rebounding from the surface of the gas container is assumed to be equal to the pressure. The assumption that matter is made up of microscopic particles that are always in motion forms the foundation of the kinetic-molecular theory, which explains the states of matter.

The observable characteristics and behaviours of solids, liquids, and gases are explained by this theory. The kinetic theory of gases has three primary parts, which are as follows: 1) Neither energy is gained nor lost when molecules collide. 2) In a container, the space occupied by gas molecules is extremely minimal. 3) These molecules move in a straight line at all times.

Which type of bond is present in hydrogen sulfide (H2S)? The table of electronegativities is given
LuckyWell [14K]

Bonds formed between atoms can be classified as ionic and covalent

Ionic bonds are formed between atoms that have a high difference in the electronegativity values.

In contrast, bonds formed between atoms that have a difference in electronegativity lower than the ionic counterparts are polar covalent bonds.  If the atoms have very similar electronegativities, they form non-polar covalent bonds.

In H2S, the S atom is bonded to 2 H atoms. The electronegativity of H = 2.2 and S= 2.56. Since the difference is not high the bond formed will be covalent (polar covalent).

Material of density of 762 kg/m3 occupies a container
konstantin123 [22]

Answer:

The answer is

<h2>0.075 kg</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density = 762 kg/m³

We must first convert the volume from cm³ to m³

1 \:  {cm}^{3}  = 1 \times  {10}^{ - 6}  {m}^{3}

So 99 cm³ will be

9.9 \times  {10 }^{ - 5}  \:  \:  {m}^{3}

So the mass of the material is

mass = 762 \times 9.9 \times  {10}^{ - 5}  \\  = 0.075438

We have the final answer as

<h3>0.075 kg</h3>

Hope this helps you

A cylinder with a moveable piston contains 0.552 mol of gas and has a volume of 259 mL . Part A What will its volume be if an ad
Naddik [55]

Answer:

The new volume will be 367mL

Explanation:

Using PV = nRT

V1 = 259mL = 0.000259L

n1 = 0.552moles

At constant temperature and pressure, the value is

P * 0.000259 = 0.552 * RT ------equation 1

= 0.552 / 0.000259

= 2131.274

V2 = ?

n2 = 0.552 + 0.232

n2 = 0.784mole

Using ideal gas equation,

PV = nRT

P * V2 = 0.784 * RT ---------- equation 2

Combining equations 1 and 2 we have;

V2 = 0.784 / 2131.274

V2 = 0.000367L

V2 = 367mL
