Answer:

Explain both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigon planar; the carbon atom exhibits sp2 hybridization. Two of the sp2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule. The remaining sp2 hybrid orbital forms a σ bond to the oxygen atom. The hybridized p orbital on the carbon atom in the carbonyl group overlaps a p orbital on the oxygen atom to form the π bond in the double bond.ation .

Answer:

Knowing how elements and compounds react together is essential in everyday life is essential to people like a scientist and someday you might become a scientist no matter what you become you will have to learn all that you can.

UwU Hope I helped

Answer:

it is very important to know how elements and compounds react together because everything that surrounds us is made out of elements and compounds. Therefore, understanding how these work can allow us to have a better understanding of the world that surrounds us. Moreover, it can avoid accidents when we deal with dangerous compounds, such as when we cook or clean

Explanation:

Answer:

C4H2O6

Explanation:

Answer:

Molecular formula = SF₆

Empirical formula is SF₆

Explanation:

Percentage of sulfur = 21.95%

Percentage of fluorine = 78.03%

Molar mass of compound = 146.1 g/mol

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of S = 21.95 / 32= 0.69

Number of gram atoms of F = 78.03 / 19 =  4.107

Atomic ratio:

                                  S                  :         F

                                0.69/0.69      :       4.107/0.69

                                     1                :         6

S : F =  1:6

Empirical formula is SF₆

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass :

32 + 19×6 = 146

n = 146.1 / 146

n = 1

Molecular formula = n (empirical formula)

Molecular formula = 1 (SF₆)

Molecular formula = SF₆

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.

Answer:

V = 29.3 inch³

Explanation:

Given data:

Diameter of cone = 4 inch

Height of cone = 7 inch

Volume of cone = ?

Solution:

Formula:

V = πr²h/3

we calculate the radius from diameter,

r = 4 inch/2 = 2 inch

Volume:

V = 3.14 ×(2 inch)²  × 7 inch/3

V = 3.14 × 4 inch² × 7 inch/3

V = 29.3 inch³

Answer:

because the minerals in the rock can't be used until they are separated

Answer:

Oxygen

Explanation:

Cellular respiration is the metabolic process that involves the breakdown of glucose molecule in order to synthesize energy in form of ATP. However, this cellular respiration can either be aerobic or anaerobic depending on whether oxygen is used or not.

Aerobic cellular respiration is the respiration that involves the use of OXYGEN. It occurs in the mitochondria of the cell, where oxygen is used as the final electron acceptor. Hence, according to the question, OXYGEN is used up during cellular respiration.

Answer:

100 milliliter

Explanation:

Initial Pressure P1 = 60 kPa

Final Pressure P2 =   120 kPa

Initial Volume V1 = 200mL

Final Volume V2 = ?

These parameters are related by the following boyle's law which is mathematically given as;

V1P1 = V2P2

Making V2 subject of interest;

V2 = V1P1  / P2

inserting the values;

V2 = 200 * 60  /  120

V2 = 100ml

Answer:

Energy is neither created nor destroyed.

Explanation:

The law of conservation of energy states that energy can neither be created nor be destroyed. The total energy of an isolated system remains conserved. It never gets 0. It changes from one form of energy to other but never vanishes.

Hence, the correct option is (d) "Energy is neither created nor destroyed"

Answer:

Absorbs, Releases

Explanation:

The formation of an ionic compound involves the transfer of electrons. The removal of one or more electrons from a metal is a process that absorbs energy, whereas the addition of one or more electrons to a nonmetal releases energy.

Answer:

Absorbs

Release

Explanation:

The formation of ionic compounds occurs between two kinds of atoms having a large electronegativity difference (Δx ≥ 0.7) e.g metals (like those in group IA and IIA) and non-metals(like those in groups VIA and VIIA). The formation of an ionic bond involves the transfer of electron(s) from the less electronegative atom (metal) to the more electronegative atom (non-metal) such that the two kinds of atoms now have a completely filled outer shell like the noble gas.

Answer:

Whether the forces of attraction is strong or weak is explained below in details.

Explanation:

There are three distinct kinds of intermolecular forces in expressions of energy. They are (strongest to weakest) dipole-dipole, hydrogen bonding, and Van der Waals' strengths. Intermolecular forces are weak related to intramolecular forces – the energies which endure a molecule collectively. For instance, the covalent bond, including distributing electron sets among atoms, is much more powerful than the forces impersonate among neighboring molecules.

Answer:

Mass of NaBr produced  = 23.67 g

Explanation:

Given data:

Mass of AgBr = 42.7 g

Mass of NaBr produced = ?

Solution:

Chemical equation:

2Na₂S₂O₃ + AgBr    →    NaBr + Na₃(Ag(S₂O₃)₂

Number of moles of AgBr:

Number of moles = mass/molar mass

Number of moles = 42.7 g/ 187.7 g/mol

Number of moles = 0.23 mol

now we will compare the moles of AgBr with NaBr.

             AgBr        :         NaBr

                1            :           1

              0.23       :         0.23

Mass of NaBr:

Mass = number of moles × molar mass

Mass = 0.23 mol × 102.89 g/mol

Mass = 23.67 g

Answer:

Mass of zinc react with oxygen = 156.91 g

Explanation:

Given data:

Volume of oxygen = 18.9 L

Temperature = 15°C

Pressure = 1.50 atm

Mass of zinc react with oxygen = ?

Solution:

Chemical equation:

2Zn + O₂     →       2ZnO

Number of moles of oxygen:

PV = nRT

1.50atm ×18.9 L = n× 0.0821 atm.L / mol.K × 288 K

28.35 atm.L =  n× 23.64atm.L / mol

n = 28.35 atm.L  / 23.64atm.L / mol

n = 1.2 mol

Now we will compare the moles of oxygen and Zn.

             O₂          :           Zn

               1            :            2

              1.2          :        2/1×1.2 = 2.4 mol

Mass of zinc required:

Mass = number of moles × molar mass

Mass = 2.4 mol × 65.38 g/mol

Mass = 156.91 g

Answer:

The correct symbol for Nitrogen is N.

Answer:

 2Fe +  3CuSO₄  →  Fe₂(SO₄)₃   +  3Cu

Explanation:

The reactants are:

   Iron  = Fe

  Copper (II) sulfate solution = CuSO₄

The reaction is given as:

            Fe +  CuSO₄  →  Fe₂(SO₄)₃   +  Cu

This is a single displacement reaction;

  Now let us balance the equation;

             aFe +  bCuSO₄  →  cFe₂(SO₄)₃   +  dCu

Conserving Fe;

                       a  = 2c

  Conserving  Cu;

                      b  = d

  Conserving S;

                      b  = 3c

  Conserving O;

                    4b  = 12c  

let b  = 1;

    c = [tex]\frac{1}{3}[/tex]  

     d  = 1

     a  = [tex]\frac{2}{3}[/tex]

Multiply through by 3 to get whole numbers;

  a  = 2, b = 3, c  = 1 and d  = 3

           2Fe +  3CuSO₄  →  Fe₂(SO₄)₃   +  3Cu

EASY ITS BUILT DIFERENT

Explanation:

Answer:

Explanation:

Given data:

Mass of alcohol = 400 g

Specific heat capacity of alcohol = 2.43 J/g°C

Initial temperature of alcohol = 16°C

Mass of water = 400 g

Specific heat capacity of water = 4.19 J/g°C

Initial temperature of water = 85°C

Final temperature of mixture = ?

Solution:

Equation:

m₁c₁ (T₂-T₁ ) = m₂c₂(T₂-T₁)

by putting values,

400 × 4.19  × (T₂ -  85°C) = 400 × 2.43  × (T₂ - 16°C)

1676  × (T₂ -  85°C) = 972 × (T₂ - 16°C)
