Zinc is listed above copper on the activity series, this means that zinc is more easily oxidized than copper.

In an atom model, the first energy level can hold _____ electrons, the second level can hold _____ electrons, and the third level can hold _____ electrons.

Answers

Answer:

In an atom model, the first energy level can hold 2 electrons, the second level can hold 8 electrons, and the third level can hold 18 electrons.

Explanation:

The Electronic Configuration of the elements is the arrangement of all electrons of an element in energy levels and sub-levels (orbitals).  

There are 7 energy levels, numbered from 1 to 7, and in which electrons are distributed, logically in order according to their energy level. Electrons with less energy will be spinning at level 1. Each level is divided into sub-levels. These sub-levels into which each level is divided can be up to 4. These 4 sub-levels are called: s, p, d, f. In the sub-level s there can only be a maximum of 2 electrons, in p there can be a maximum of 6 electrons, in the sub-level d 10 electrons and finally in the sub-level f there can be a maximum of 14 electrons.

In level 1 there is only one sub-level, which will be the s. In level 2 there are 2 sub-levels, the s and the p. At level 3 there are 3 sub-levels s, p and d. And at level 4 there are 4 sub-levels, the s, the p, the d and the f.

Then, in an atom model, the first energy level can hold 2 electrons, the second level can hold 8 electrons, and the third level can hold 18 electrons.

If there are 5 protons, there should be 5 electrons as well. Boron as an electron configuration of 2-3 or 1s2 2s2 2p.

What is proton ?

The term proton is defined as a subatomic particle found in the nucleus of every atom. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron.

The protons are considered as elementary particles. The protons are called to be composite particles, containing three valence quarks, and together with neutrons are now classified as hadrons.

Boron has an atomic number of 5. In which it has 5 protons. Therefore, the atom also has 5 electrons. Its atomic mass is 10.811. Thus, it has 11 total particles in its nucleus i.e., protons and neutrons.

How many valence electrons do the elements in column 4 have? Are these elements very reactive?

Answers

Answer:

Explanation: Elements in group 14 have 4 valence electrons. Meaning that to achieve a stable octet they need to either gain or lose 4 electrons in total. That would take significantly more energy than other elements, e.g., group 1 (alkaline metals) or group 17 (halogens.)

Explanation:

In the periodic table, the elements in column 4 have four valence electrons and are less reactive compared to s- block elements but more reactive than the p-block elements.

What is periodic table?

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

Calculate the total pressure in a mixture of 8 g of dioxygen and 4 g of dihydrogen confined in a vessel of 1 dm8 at 27 ∘C. (R = 0.083 bar dm8 K−1 mol−1​

Answers

Answer:

Total pressure =  56.77 bar

Explanation:

Given data:

Mass of dioxygen = 8 g

Mass of dihydrogen = 4 g

Volume of vessel = 1 dm³

Temperature = 27°C (27+273 = 300 K)

R = 0.083 bar.dm³ / mol.K

Total pressure = ?

Solution:

Number of moles of dioxygen:

Number of moles = mass/molar mass

Number of moles = 8 g/ 32 g/mol

Number of moles = 0.25 mol

Pressure of dioxygen:

PV = nRT

P = nRT/V

P = 0.25 mol × 0.083 bar.dm³ / mol.K × 300 K / 1 dm³

P = 6.97 bar.dm³  /1 dm³

P = 6.97 bar

Number of moles of dihydrogen:

Number of moles = mass/molar mass

Number of moles = 4 g/ 2 g/mol

Number of moles = 2 mol

Pressure of dihydrogen:

PV = nRT

P = nRT/V

P = 2 mol × 0.083 bar.dm³ / mol.K × 300 K / 1 dm³

P = 49.8 bar.dm³  /1 dm³

P = 49.8 bar

Total pressure of mixture in a vessel:

Total pressure = P (O₂) + P(H₂)

Total pressure =  6.97 bar + 49.8 bar

Total pressure =  56.77 bar

Why does salt sprinkled on icy roads cause the ice to melt?​

Answers

it lowers the melting point

Answer:

The actual reason that the application of salt causes ice to melt is that a solution of water and dissolved salt has a lower freezing point than pure water. When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.

. A certain quantity of electricity is passed through an aqueous

solution of AgNO3 and cupric salt solution connected in series. The

amount of silver deposited is 1.08 g. What is the amount of copper

deposited ? (Atomic wt. of Cu=63.54, Ag=108 g/mole).​

Answers

Answer:

0.32 g

Explanation:

First, we find the number of moles n of silver deposited.

n = m/M where m = mass of silver deposited = 1.08 g and M = Atomic weight of silver = 108 g/mol

n = m/M = 1.08 g/108 g/mol = 0.01 mol

Now, the quantity of electricity Q = nF where n = number of moles of silver = 0.01 mol and F = Faraday's constant = 96500 C/mol

Q= nF = 0.01 mol × 96500 C/mol = 965 C

By the chemical equation for copper,

Cu²⁺ + 2e ⇒ Cu

2 moles of electrons deposits 1 mol of copper, that is

2 × 96500 C deposits 1 mol of copper, then 965 C will deposit x mol

x = 1 mol × 965 C/2 × 96500 C = 1/200 mol = 0.005 mol of copper

So, we find the mass of 0.005 mol of copper using

n = m/M where m = mass of copper deposited = unknown and M = Atomic weight of copper = 63.54 g/mol and n = number of moles of copper = 0.005 mol

m = nM

= 0.005 mol ×  63.54 g/mol

= 0.32 g
