whats the difference between a bonding electron domain and a nonbonding electron domain?​

Answer:

yes true

Explanation:

both are heterogeneous

Answer:

(6.3x10^23)/(6.02x10^23) = 1.047 mol Cl

The number of moles of the chlorine atoms in the 6.022 × 10²³ molecules of chlorine is equal to 2.10 mol.

Avogadro’s number can be used to express the number of entities in one mole of any substance and these units can be atoms, molecules, ions, electrons, or protons, depending upon the kind of chemical reaction or reactant and product.

The Avogadro’s constant has a numerical value approximately equal to 6.022× 10²³ mol⁻¹.

Given, the number of molecules of chlorine = 6.3× 10²³

As the one chlorine mole has chlorine atoms = 2

The number of moles of chlorine molecules in 6.3× 10²³ will be :

= 6.3× 10²³/ 6.022× 10²³ = 1.05 moles

One mole of chlorine molecules has Cl atoms = 2 moles

1.05 moles of chlorine molecules have Cl atoms = 2 × 1.05 = 2.10 mol

Therefore, the number of moles of Chlorine atoms is equal to 2.10.

Answer:

Neutrons and Protons, Electrons

Explanation:

Neutrons and protons are in the inside as electrons orbit around it in a circular pattern

Answer:

the rate of heat transfer is directly proportional to the mass flow rate.

Explanation:

There is an elementary equation from basic thermodynamics that states that the rate of heat transfer (Q) equals the mass flow rate (M) times a Constant (the specific heat of water) times the Delta T (fluid temp out minus fluid temp in): Q = M x C x Delta T In other words, the rate of heat transfer is directly proportional to the mass flow rate.

Answer:  There are many properties of a metal which is taken into consideration when it is used for construction

Explanation:

The properties can be physical, chemical, et cetera. The physical properties that is considered are:

1. Durability:  It can be defined as the property of the material to withstand the atmospheric pressure and other factors.

2. Density: The ratio of mass by volume of a material (homogeneous material) is called as density.

3. Fire resistance: The ability of the material to withstand in fire without changing its size or shape.

4. Weather resistance: The ability of the material to withstand the weather which could be variable round the year.

5.Water absorption: The ability of the material to absorb water and retain it.

Which statement about photosynthesis is FALSE?

Answer:

b. Oxygen is needed as a reactant to produce

glucose is the incorrect statement here

Explanation:

plants uses simple raw materials to prepare their food , which includes water ( H2O ) and Carbon dioxide ( CO2 ).

and traps sunlight by Green pigments known as chlorophyll and stores these energy in bonds of glucose molecules

so ,

after this reaction glucose and oxygen is formed as products

● hence we conclude that Oxygen is not needed as a reactant to produce glucose , oxygen is the bi product formed during photosynthesis.

Answer:

Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full.

Elements: Argon

Total moles of gas = 0.1225

Volume of gas produced : 6.7375 L

mass of Nitrogen : 0.588 g

Given

2 ml of Nitroglycerin(ρ=1.592 g/ml)

Required

Total moles of gas

Solution

Nitroglycerin detonated ⇒ decomposition reaction

4C₃H₅N₃O₉(s)⇒ 6N₂(g)+12CO(g)+10H₂O(g)+7O₂(g)

mass of Nitroglycerin :

Answer:

Beautiftul, begging under F

honest, beginning in thrid line under A

hopeful, fifth line under F

Explanation:

Answer:

The main difference between an atom and a molecule lies in the size: while the atom is the smallest unit into which matter can be divided into any of its states, a molecule is the union of a group of atoms, that is, this composed of several atoms. Thus, for example, a water molecule is composed of two hydrogen atoms and one oxygen atom (H2O). Therefore, it can be said that atoms are the smallest unit in which the chemical elements of the world can be divided, while molecules are the particles of matter that are formed through the combination of these elements.

Answer:

C) Electrons will reside closer to chlorine, and the bond will be polar

Explanation:

Electrons tend to be closer or attracted to high electronegativity and sulfur has less electronegativity than chlorine. Therefore, electrons will reside closer to chlorine. To find out if it is polar or nonpolar, according to the electronegativity chart you can find online, you can see that the electronegativity of sulfur is 2.5 while the electronegativity of chlorine is 3.0. Because the difference between these two is a slight change, it would be slightly polar. So, the bond will be polar.

Answer:

Electrons will reside closer to chlorine, and the bond will be polar.

Answer:

replacement

Explanation:

There are two types of replacement reactions.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

The given reaction is double replacement reaction because anion and cation of both reactants exchanged with each other.

Other options are incorrect because,

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Elements which composed of an equal amount of three components protons, neutrons and electrons are considered neutral elements. example of neutral elements are hydrogen, helium, lithium and beryllium...

Answer:

Well, acutally it shouldnt..but why it should be recycled is because 1. you can use it for many nessactities such as cars and blades, and bikes

You should also recycle it for, scrap parts! so just in  case if you need recycled steel ya know where to get it

Lastly, you should recycle steel because of its value. If you recycle steel then melt it, and make well i dont know, a blade out it, you might have just made something, and then think, "Well that was fun and easy, i wanna use more recycled items to build or forge things

Explanation:

Hope this helps and pls mark brainlest!

Answer:

i think because its cause pollution

Explanation:

when making steel a lot of pollution goes in the atmosphere so if you recyle the the steel we may less pollution [ im only 12 so im sorry if this was wrong]

Explanation:

when magnesium metal reacts with oxygen present in air it burns with a white dazzling flame

to form white powder of magnesium oxide (MgO)

here's the balanced chemical reaction for it

2Mg+O2->2MgO

Answer: [tex]2Al(OH)_3+3H_2CO_3\rightarrow Al_2(CO_3)_3+6H_2O[/tex]

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants.

The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation will be :

[tex]2Al(OH)_3+3H_2CO_3\rightarrow Al_2(CO_3)_3+6H_2O[/tex]
