There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane​

Answers

Answer:

C. the carbons in ethene are linked by double bonds

Explanation:

The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.

In single bonds afforded with the ethane compound, there is free rotation.

The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity

Answers

Answer:

The final velocity of the motorcycle is 64.7 m/s

Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation

Explanation:

Using the equation of motion that contains all the given values in the question: v² = u² + 2as

where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance

v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m

v² = 0² + 2 * 4.55 * 460

v² = 4186

take square root of both sides

v = 64.7 m/s

Therefore, the final velocity of the motorcycle is 64.7 m/s

A student cut out a spiral shape from a piece of tissue paper and hung it from a string over a light bulb. Nothing happened. Next the student turned on the light. After a few seconds, the spiral began to turn above the light. Which of these best explains what happened?​

Answers

Answer:

See explanation

Explanation:

Initially, when the paper is hung over the light bulb, we observe that nothing happens at all.

As time goes on, air surrounding the lamp begins to heat up. Remember that hot air is lighter and less dense than cold air.  Air surrounding the lamp which has now become hotter and less dense rises and pushes on the spiral. This causes the spiral to begin to spin.

A. The element on the left would have more atomic mass.

B. The element on the left would have less malleability.

C. The element on the left would have a lower melting point.

D. The element on the left would have no metallic properties.

Answers

Answer:

C

Explanation:

An element on the left side of row 2 of the periodic table differ from the middle element of the same row because they have a lower melting point.

What is melting point?

It is that point where solid state of a substance changes to liquid state.

In the second row of period table as we move towards right from the left side i.e. from Lithium (Li) to Neon (Ne) atomic mass of the elements increases simultaneously melting point of that elements also increases, due to bulkiness.

Hence option (c) is correct .i.e. elements on the left would have a lower melting point.

Examine the layers of rock. How does layering provide evidence for determining geologic age?

Answers

Well I can’t see the rocks but, to determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones.



Hope this helped! <3

Answer:

the deeper you go down in to the rock the older the fossils get.

Explanation:

layering can provide evidence because the deeper you go down in to the rock the older the fossils get. So when the scientists go in to the rock they can say what animals lived in that time and what animal was the oldest.

Explanation:

The sedimentary rocks that are formed from physical/chemical process within the earth are given the general name of chemical precipitation.

What do you mean by the chemical precipitation ?

Chemical precipitation is the process of turning a liquid into a solid by either making the liquid insoluble or making it very saturated.

Chemical precipitation, which starts when water moving through rock dissolves part of the minerals, creates chemical sedimentary rocks. When the water evaporates, the minerals are finally redeposited or precipitated after being moved away from their source.

A chemical compound that develops when the solution it was dissolved in, often water, evaporates and leaves the compound behind is known as a chemical precipitate.

Thus,Chemical precipitation is the process that gives rise to chemical sedimentary rocks including limestone, halite, and flint.

Calcium carbonate (limestone) decomposes when heated.
Caco, + CaO + CO2

b) Calculate the volume of carbon dioxide produced if 10 grames were decomposed.​

Answers

Explanation:

Equation -

CaCO₃ → CaO + CO₂

molecular masses of -

CaCO₃ = 40+12+16×3 = 100 g/mol

CaO = 40+16 = 56 g/mol

CO₂ = 12+16×2 = 44 g/mol

Now,

If 100 g of CaCO₃ is decomposed then it produces 56 g of CaO and 44g of CO₂

Then,

If 1 g of CaCO₃ is decomposed then it produces 56/100g of CaO and 44/100g of CO₂

Now,

Here in question, 10g of CaCO₃ is decomposed

It means, It produces

56/100 × 10 = 56/10 = 5.6 g of CaO and

44/100 × 10 = 44/10 = 4.4 g of CO₂

Now,

we get that 10 g of CaCO₃ on burning produces 4.4 g of CO₂

we need to calculate volume of 4.4 g of CO₂

mole = mass/Gram molecular mass

Then,

mole = 4.4/44 = 0.1

Now,

volume = mole × 22.4 (in Litres)

= 0.1 × 22.4 = 2.24 L

Hence,

2.24 L of CO₂ will be produced when 10g of CaCO₃ decomposed.

157

Answers

Answer:

A)  0.0499

Explanation:

According to the mole concept, 2.80 g of calcium oxide sample  has 0.0499 moles.

What is mole concept?

According to the mole concept,mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

As per the formula for number of moles, which is mass/molar mass

number of moles of calcium oxide is:2.80/56.08=0.0499 moles.

Hence, 2.80 g sample of calcium oxide has 0.0499 moles.

Now Napoleon's France followed in the footsteps of the English.Napoleon's 35,000-man army was led by his brother-in-law and soon scored an amazing success: They captured Toussaint in 1802 and brought him to France, where he died in prison in 1803. But the former slaves fought on. In two years of fighting, nearly 50,000 French soldiers died. And on January 1, 1804, the victorious Republic of Haiti was born. Fighting for freedom, the former slaves defeated the armies of first England, then France: Europe's two most powerful nations.Haiti was born free; human rights won over property rights.In 1807 a bill to ban all English involvement in slave trading passed the House of Commons, then the House of Lords. At precisely noon on March 25, King George III signed the law. We should mark that date, honor it, to this day. For while no slaves were freed by the bill, it marked a great change in the world. More slaves from Africa had been shipped by the British than by any other nation. That part of the grim history of sugar and slavery was over. Indeed, that very same year Congress passed a law forbidding Americans from being involved in importing slaves. In the great contest over whether a human, any human, could ever be property; the tide was turning.How do the authors develop the claim in the two passages?Both passages help the reader understand how the end of involuntary servitude in Haiti led to the end of involuntary servitude in Britain.Both passages illustrate how property rights were more important to the British than to Americans.Both passages support the claim that human rights became more important than property rights in the early 1800s.Both passages support the claim that the end of the slave trade eventually led to the end of the sugar industry.
