These bonds occur when ELECTRONS are transferred from one atom two ANOTHER, and are a result of the attraction between the resulting oppositely charged ions.

Chemical bonds are the forces that HOLD atoms TOGETHER in COMPOUNDS.

THANKS❗❗❗

Explanation:

Metallic bonding is a TYPE of chemical bonding that rises from the electrostatic ATTRACTIVE force between conduction electrons and positively CHARGED metal ions. It MAY be described as the sharing of free electrons AMONG a structure of positively charged ions.

Explanation:

The copper(II ions are the oxidizing agent. The IRON oxide undergoes reduction (loses OXYGEN) to form iron while the carbon MONOXIDE is oxidized (gains oxygen) to form carbon dioxide. In this CONTEXT, iron(III) oxide is the oxidizing agent which gives oxygen to another MOLECULE.

Answer:-

Any chemical ELEMENT that is an EFFECTIVE CONDUCTOR of electricity and HEAT can be defined as a METAL.

Explanation:

A chemical BOND is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or ELECTROSTATIC FORCES.

Explanation:

Oxidation number, also called Oxidation STATE, the total number of ELECTRONS that an atom either gains or LOSES in order to FORM a chemical BOND with another atom.

BONE cells such as osteoclasts, osteoblasts, and osteocytes 'talk' to each other THROUGHOUT adult life to maintain bone integrity.

The matrix of bone contains inorganic salts, primarily hydroxyapatite and some calcium carbonate, and collagen fibers. These and a few other salts are deposited in a framework of collagen fibers, by a process called CALCIFICATION.

Explanation:  

When Neha MAKES a soup, she doesn't get the VEGETABLE BACK from the soup.

Soup is made by CHEMICAL CHANGE. Heat and light melt the vegetable which is mainly an irreversible change.

So she can’t get back the vegetables from the soup.

This is a chemical change and it is doing by heat and light. The action that is shown here is irreversible action in which anything cannot get back to their previous stage.

which QUESTION is that ??

Answer:

1. Brass is an alloy

made primarily of copper and zinc. The proportions of the copper and zinc are varied to YIELD many different kinds of brass. Basic modern brass is 67% copper and 33% zinc. However, the AMOUNT of copper may RANGE from 55% to 95% by weight, with the amount of primarily of copper, commonly with about 12-12.5% tin and often with the addition of other metals (such as aluminium, manganese, nickel phosphorus or silicon.

zinc varying from 5% to 40%.

2. Bronze is an alloy consistingor zinc) and sometimes non-metals or metalloids such as arsenic,

3. A higher tin composition gives the solder higher corrosion resistances,

but raises the melting point. Another common composition is 11% tin, for soldering components that are

37% lead, 42% bismuth, and 10% cadmium. This combination has a low melting point and is useful

sensitive to heat

4. In metallurgy, STAINLESS steel, also known as inox steel or inox from French inoxydable (inoxidable), is a steel alloy, with a minimum of 10.5% CHROMIUM content by mass and a maximum of 1.2% carbon by mass.

Answer:

Ideal Gas LAW :  

PV = nRT

No. of moles (n) = N1 + n2

where  

n1 = No. of moles of Helium

n2 = No. of moles of Argon

1 atm x 10 L = (n1 + n2) x 0.0821 x (273+25)

n1 + n2 =  0.4087 ..........................................(1)

No. we know  

No. of moles x Molar mass = given mass

Therefore

(Molar mass x No. of moles of He ) +​(Molar mass x No. of moles of argon ) = Mass of sample

4n1 + 39.9 n2 = 5 .........................................(2)

[SOLVING equation 1 and 2 simultaneously for the value of n1 and n2 as follows :]

4 x (n1 + n2 =  0.4087 ) .............(3)

1 x (​4n1 + 39.9 n2 = 5 )................(4)

[subtracting eq 3 from 4 we get]  

35.9 n2 = 3.3652

n2 = 0.0937 moles of Argon

Mass of argon present = 0.0937 x 39.90 = 3.7386 g

Mass of helium present = 5g - 3.73863g = 1.2613 g

Mass % of He = (1.2613/5) x100 = 25.2274 % Helium

Mass % of Ar = (3.7386/5) x 100 = 74.772 % of Argon
