Gives 2 reaction in which benzene ring is retained and 2 reaction in which benzene ring is not retained
Hey dear,
Benzene is a 6-C cyclic structure with alternate double bonds.
● Reactions -
1) Benzene to cyclohexane -
Benzene can be reduced to cyclohexane with
the help of Ni/H2. C6H6 + 3H2 --> C6H12
All 3 double bonds in ring are reduced here.
2) Benzene to benzoquinone - Benzene can be oxidized to benzoquinone with
the help of acidic K2Cr207. C6H6 +3[O] --> C6H4O2 + H2O
Only 1 double bond is lost in this reaction.
Hope this helps you.

You compare the gas generated from a reaction using two antacid tablets with the gas generated from a reaction using four antacid tablets (consider the antacid as the limiting reagent).
At constant pressure and temperature, how do the volumes of the gases compare?
The two reactions produce the same amount of gas.
The gas generated by four antacid tablets has a smaller volume.
The gas generated by two antacid tablets has a smaller volume.
Answer: The gas generated by two antacid tablets has a smaller volume.
Explanation:
Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.
This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.

If 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate, determine the molarity of the lead (II) nitrate solution. Note: First write the balance equation between potassium iodide and lead (II) nitrate.
The molarity of the lead(II) nitrate solution if 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate is 1.2M.
How to calculate molarity?The molarity of a solution can be calculated using the following formula:
CaVa/CbVb = na/nb
Where;
Ca = concentration of acidCb = concentration of baseVa = volume of acidVb = volume of basena = number of moles of acidnb = number of moles of baseThe balanced equation of the reaction is as follows:
Pb(NO3)2 (aq) + 2KI (aq) → 2KNO3 (aq) + PbI2 (s)
22 × 2/18 × Cb = 2/1
44/18Cb = 2
Cb = 44 ÷ 36
Cb = 1.2M
Therefore, the molarity of the lead(II) nitrate solution if 22.00 mL of 2.00 M potassium iodide is needed to reach the equivalence point with 18.00 mL of lead (II) nitrate is 1.2M.

When heated, KClO3 decomposes into KCl and O2. 2KClO3⟶2KCl+3O2 If this reaction produced 17.4 g KCl, how many grams of O2 were produced? maSS
Answer:
12.6 g O2 or
12.60 g O2 (if needed two decimal places)
Explanation:
First convert grams into moles:
17.4 g KCl × 1
74.55
= 0.233 moles of KCl
Next solve for the mole of O2:
= 0.233 × 3 moles of O2
2 moles of KCl
= 0.3495 or
= 0.350 moles of O2
Finally convert the mole to grams:
= 0.350 moles of O2 × 36g
1 mole
= 12.6 g O2 or 12.60 g O2
Answer:
a car traveled 20m &400k/g

Calculate the concentration of Nations in solution.
Taking into account the definition of molarity, the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].
Definition of molarityMolar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]Molarity=\frac{number of moles}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{lliter}[/tex].
Concentration of Na₃PO₄ in solutionBeing the molar mass of Na₃PO₄ 163.94 g/mole, that is, the amount of mass that a substance contains in one mole, the amount of moles that contains 23.6 g sample of Na₃PO₄ is calculated as:
[tex]23.6 gramsx\frac{1 mole}{163.94 grams} = 0.144 moles[/tex]
Then you know:
number of moles= 0.144 molesvolume= 750 mL= 0.750 L (being 1000 mL= 1 L)Replacing in the definition of molarity:
[tex]Molarity=\frac{0.144 moles}{0.750 L}[/tex]
Solving:
Molarity= 0.192[tex]\frac{moles}{lliter}[/tex]
Finally, the concentration of Na₃PO₄ in solution is 0.192[tex]\frac{moles}{lliter}[/tex].

Hydrocarbons are insoluble in water because :-
1)Hydrocarbons are nonpolar whereas water is polar. (like dissolves like).
2) Hydrocarbons and water do not exhibit appropriate solvent-solute interactions. Hydrocarbons only form very weak dispersion forces whereas water produces strong polar hydrogen bonding interactions.

B .They have xylem vessels and phloem vessels
C . They are able to push water and nutrients to each part of the plant.
D . They are found in moist environments.
Answer:
D . They are found in moist environments.
Explanation:
Nonvascular plants do not have a xylem or phloem, roots, stems, or leaves. Because these plants lack water-conducting tissues, they fail to achieve the structural complexity and size of most vascular plants and have evolved in habitats which allow their survival and reproduction.
The plant body that is most obvious in non-vascular plants are the the gametophyte generation. The gametophte gemeration is haploid.
The non-vascular plants grow in moist environments. It is due to lack of vascular tissue that requires to maintain close contact with water to prevent desiccation. Nonvascular plants are plants that do not have any special internal pipelines or channels to carry water and nutrients. Instead, nonvascular plants absorb water and minerals directly through their leaflike scales. Nonvascular plants are usually found growing close to the ground in damp, moist places. Non-vascular plants thrive in damp conditions since they don't need to rely on roots to acquire enough water.
