Answer: Chemistry is the study of change. Various reasons why to study Chemistry is to appreciate the fundamentals of the world such as the composition of all living thing. We are made up of matter. The interaction of sub atomic particles in an atom to form a single being. Also to understand how certain chemicals are beneficial and harmful in our lives just by reading product labels.

What descriptive term is applied to the type of diene represented by 2,4-hexadiene?.
Varvara68 [4.7K]

The descriptive term applied to the type of diene represented by 2,4-hexadiene is conjugated diene.

Dienes are compounds which contains two double bonds. These dienes can be non conjugated or conjugated.

Conjugated diene are those compound which have two double bonds  joined by a single σ bond. Conjugated dienes can also be called 1,3-diene. To know if diene is conjugated or non conjugated, sp³ hybridization is to b checked and the number of double bonds and single sigma bond is checked.

Conjugated dienes are found in many different molecules. 2,4-hexadiene is a conjugated diene with two carbon-carbon double bonds that are separated by one sigma bond.

The stabilization of dienes by conjugation is better than the aromatic stabilization. Conjugated dienes are more stable than non conjugated or cumulative diene because it has higher electron density of molecules delocalized.

To learn more about conjugated dienes,

What is the mass in 6.34x10^23 molecules of calcium chloride
Liono4ka [1.6K]

Answer : The mass of calcium chloride is, 116.84 grams

Solution : Given,

Molar mass of calcium chloride, CaCl_2 = 110.98 g/mole

Number of molecules of calcium chloride = 6.34\times 10^{23}

As we know that,

1 mole of calcium chloride contains 6.022\times 10^{23} molecules of calcium chloride

or,

1 mole of calcium chloride contains 110.98 grams of calcium chloride

Or, we can say that

As, 6.022\times 10^{23} molecules of calcium chloride present in 110.98 grams of calcium chloride

So, 6.34\times 10^{23} molecules of calcium chloride present in \frac{6.34\times 10^{23}}{6.022\times 10^{23}}\times 110.98=116.84grams of calcium chloride

Therefore, the mass of calcium chloride is, 116.84 grams

The reaction between zinc (Zn) and hydrogen chloride (HCl) produces zinc chloride (ZnCl), hydrogen (H2) gas, and heat. If more h
andrew-mc [135]

 If more   heat  is removed from the reaction the rate of reaction change as below to counter the action

The rate of the  <em>forward reaction increase</em> and produces more   <em>zinc chloride</em>


<u><em>      explanation</em></u>

  • <u><em> </em></u>The reaction of  zinc and HCl  to produce ZnCl and H2 <u><em>is </em></u> exothermic reaction,  heat  is produced as one product   and by  removing  heat  it favor   forward reaction
  • The position  of equilibrium  moves to the right since  removing  heat led to decrease of temperature  and more  zinc chloride   is produced.
