Answer:

False

Explanation:

''A mixture is the chemical bonding of two or more substances in any proportion'' is false statement because a mixture don't include bonding of chemical substances.  

Mixtures in chemistry are including <u>blending</u> of substances and we have two tipes of mixture:

  1. Heterogeneous
  2. Homogeneous

Some of the chemical mixtures are: mixture of water and sand, mixture of sand and iron filings and more...

If we are talking about bonding in chemistry there are Covalent bonds and Ionic bonds.

<u>Answer:</u>

<em>The statement is False. </em>

<u>Explanation:</u>

A mixture contains two or more elements present in it.

The elements are not in chemical combination with each other.

A compound too contains two or more elements but they are in chemical combination.

For example NaCl  is a compound which contains 1 part of Sodium and 1 part of Chlorine.

H_2 O is a compound 2g of hydrogen is chemically combined with 16g of Oxygen.

Chemical bonding is the attractive forces  which holds the atoms together in a molecule.

NaCl - the attractive force is called as Ionic bond.

H_2 O - the bond present is a covalent bond

A mixture has two or more elements but there is no chemical bonding present in it. The components of a mixture can be easily separated from it.

You have 4.72x10^25 atoms of a substance with MW of 136.94 g/mol How many moles do you have
slega [8]

Number of moles = 78.41

<h3>Further explanation  </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

4.72 x 10²⁵ atoms of a substance, then moles :

\tt n=\dfrac{N}{No}\\\\n=\dfrac{4.72\times 10^{25}}{6.02\times 10^{23}}\\\\n=78.41

Which of the following shows both the correct formula and correct name of an acid?
Dimas [21]

Answer is: C. H3PO4, phosphoric acid.

A) HClO₂ is chlorous acid.

Chlorous acid is weak inorganic acid. In this acid, chlorine has oxidation number +3.

B) HNO₂ is nitrous acid.

Nitrous acid is a weak monobasic acid.  In this acid, nitrogen has oxidation number +3.

D) HI is hydroiodic acid.

Hydroiodic acid is a highly acidic aqueous solution of hydrogen iodide. In this acid, iodine has oxidation number -1.

Physical reactions of carbonyl group​
docker41 [41]

Answer:

The polarity of the carbonyl group notably affects the physical properties of melting point and boiling point, solubility, and dipole moment. Hydrocarbons, compounds consisting of only the elements hydrogen and carbon, are essentially nonpolar and thus have low melting and boiling points.

Question 1: Which of the following statement is false about conjugated systems?
valkas [14]

Answer:

A conjugated system can only contain two alkenes: False

B. A cumulated diene is less stable than an isolated diene.

False

Explanation:

A. A conjugated system is more stable than an unconjugated system.: True

Due to resonance a conjugated system is more stable.

B. The s-trans isomer is favored over the s-cis isomer.: True

Due to repulsion in s-cis isomer they are less stable.

C. A conjugated system has multiple resonance structures. True

This is the reason they are stable.

D. A conjugated system can only contain two alkenes: False

A conjugated system may have may alternate double and triple bonds.

2) A trans alkene releases less heat upon hydrogenation than a cis alkene.

True

Trans alkenes are more stable than cis alkene. Thus heat of hydrogenation of trans alkene is less than cis alkene.

B. A cumulated diene is less stable than an isolated diene.

False

C. Multiple products can always form when treated a conjugated diene with HBr.  True

There can be 1,2 or 1,4 addition

D. Conjugated systems arise only between sp2-hybridized atoms.

True

Conjugation allows resonance which is possible in sp2 systems

E. Conjugated double bonds involve unhybridized p-orbitals aligned with each other

True

The double bond is formed as pi bond due to side ways overlapping of unhybridized p orbitals
