Answer:

The compound will be cyclohexane, the structure is attached.

Explanation:

Let us calculate the double bond equivalent of the given molecule, which will give us the number of double bonds or rings in the molecule.

DBE = C - (H/2) + (N/2) +1

C = 6

H = 12

N = 0

DBE = 6-6+1 = 1

So there must be a double bond or a ring

As mentioned there is not double bond then there must be a ring with no branching.

So the structure will be as shown in figure.

what volume (ml) of 3.0M NaOH is required to react with 0.8024-g copper ii nitrate?what mass of copper ii hydroxide will form as

Ksivusya [100]

The reaction between NaOH and Cu(NO₃)₂ is as follows

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂

Q1) stoichiometry of NaOH to Cu(NO₃)₂ is 2:1

this means that 2 mol of NaOH reacts with 1 mol of Cu(NO₃)₂

the mass of Cu(NO₃)₂ reacted - 0.8024 g

molar mass of Cu(NO₃)₂ is 187.56 g/mol

therefore the number of Cu(NO₃)₂ moles that have reacted

- 0.8024 g/ 187.56 g/mol = 0.00427 mol

according to the stoichiometry , number of NaOH moles - 0.00427 mol x 2

then number of NaOH moles that have reacted - 0.00855 mol

In a 3.0 M NaOH solution, 3 moles are in 1000 mL of solution

Then volume required for 0.00855 mol - 1000 x 0.00855 /3 = 2.85 mL

2.85 mL of 3.0 M NaOH is required for this reaction

Q2) Assuming that there's 100 % yield of Cu(OH)₂ , we can directly calculate the mass of Cu(OH)₂ formed from the number of moles of reactants that were used up.

Stoichiometry of Cu(NO₃)₂ to Cu(OH)₂ is 1:1

this means that 1 mole of Cu(NO₃)₂ gives a yield of 1 mole of Cu(OH)₂

the number of Cu(NO₃)₂ moles that reacted - 0.00427 mole

Therefore an equal amount of moles of Cu(OH)₂ were formed

Then amount of Cu(OH)₂ moles produced - 0.00427 mol

Mass of Cu(OH)₂ formed - 0.00427 mol x 97.56 g/mol = 0.42 g

A mass of 0.42 g of Cu(OH)₂ was formed in this reaction.

A student decides to dissolve crackers in their soup as fast as possible. They must first increase the surface area of the crack

Thepotemich [5.8K]

Answer: The correct option is A ( Break the crackers into pieces.)

Explanation:

The rate of reaction between two substances can be affected by the following factors:

--> surface area of reacting substances

--> concentration

--> reaction mechanism

--> temperature

--> the presence of a catalyst and

--> pressure ( if gaseous)

Reagents in solution tend to react faster than reagents in solid form. This is because molecules are freer to move about and collide more effectively in solutions. For example, a lump of zinc will not react as fast as powdered zinc with dilute hydrochloric acid to produce hydrogen. This is the same with the reaction between the crackers and soup. To increase the reaction of the substances, the crackers needs to be broken into pieces(thus,increased surface area)

Can some help me plz.

tankabanditka [31]

Answer:

Pythagoras was the first ancient astronomer to suggest that there was a harmony of the spheres, and that the movement of the planets, sun, moon and stars could be described by whole numbers and mathematical precision. His other discovery was that the morning and evening star are the same thing, the planet Venus.

How many resonance structures are possible for hydroxide ion?<br> A. 3<br> B. none<br> C. 2

m_a_m_a [10]

First, how many valence electrons does hydroxide ion have? If it has something like 6 it would need 2 to get the max total of 8. Or perhaps it's 7. Then only one is needed. But if the number is 8 then 0 is required

Help ASAP Please!!! What is Function chloroplast

tiny-mole [99]

Answer:

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
