Answer:

The answer is C. A single replacement reaction.

Explanation:

I did quiz.

The reaction is represented by Fe + CuSO4 → Cu + FeSO4 is single-replacement reaction . option C is correct.

A single-replacement reaction sometimes is called single displacement reaction into which a single compound as gets attached to the other compound after the completion of the reaction and we get it as a product.

Examples are Zn + 2HCL will give ZnCl + H2 gas but the condition is that the elements which are replacing must be of same in nature otherwise they will not get replace by any of them.

Therefore, reaction is represented by Fe + CuSO4 → Cu + FeSO4 is single-replacement reaction . option C is correct.

The correct answer is option A: CH3COCH3

Hydrogen bonding occurs when hydrogen is directly bonded to a highly electronegative atom.

Hydrogen bonding is one of the intermolecular interactions. It occurs only when hydrogen is bonded to a very electronegative atom in a molecule. Hydrogen bonding can occur between two molecules of the same type(intermolecular hydrogen bonding) or within the same molecule (intra molecular hydrogen bonding). In either case, the bonding is polar as hydrogen is attached to the electronegative atom via a non-covalent bonding interaction.

Looking at the structures in the question attached, CH3COCH3 does not have any hydrogen atom directly attached to a highly electronegative atom hence CH3COCH3 does not exhibit hydrogen bonding.

Hydrogen bonding in water is shown in the image attached.

Answer:

After two hours, it is observed that Genevieve's Jar has less water than that of Alden.

Explanation:

The water in Genevieve's Jar didn't disappear. It was not drunk by the birds, it simply evaporated. Evaporation is what happens to liquid when they are heated. Water has three states: Solid (that is Ice), Liquid (that is the water which was put in the jar), and gas (vapor).

When water is exposed to heat sources like the sun, its molecules vibrate faster and escape into the atmosphere in form of vapor if the container has an opening.

When this happens for a prolonged period of time, the amount of water in the jar or container becomes less and less in volume.

This is not the case for the jar that was stored in a cool place where the water molecules remained stable.

Answer:

[tex]Cr_2O_7^{2-}(aq)+2Cu^+(aq)\rightarrow Cu_2Cr_2O_7(s)[/tex]

Explanation:

Hello!

In this case, when writing net ionic equations, we first need to identify the complete molecular equation; thus for potassium dichromate reacting with copper (I) bromide, we have:

[tex]K_2Cr_2O_7(aq)+2CuBr(aq)\rightarrow Cu_2Cr_2O_7(s)+2KBr(aq)[/tex]

Thus, since all the species are aqueous except copper (II) dichromate, we can write the complete ionic equation by ionizing the aqueous ones:

[tex]2K^++Cr_2O_7^{2-}+2Cu^++2Br^-\rightarrow Cu_2Cr_2O_7(s)+2K^++2Br^-[/tex]

Finally, for the net ionic equation, we need to cancel out the spectator ions as they are present at both reactants and products sides, thus, we obtain:

[tex]Cr_2O_7^{2-}(aq)+2Cu^+(aq)\rightarrow Cu_2Cr_2O_7(s)[/tex]

Explanation:

The second volume :  V₂= 1472.9 L

Further explanation

Given

980 L at 71 C and 107.2 atm

13 C and 59.3 atm

Required

The second volume

Solution

T₁ = 71 + 273 = 344 K

P₁ = 107.2 atm

V₁ = 980 L

P₂ = 59.3 atm

T₂ = 13 + 273 = 286 K

Use combine gas law :

P₁V₁/T₁ = P₂V₂/T₂

Input the value :

107.2 x 980/344 = 59.3 x V₂/286

V₂= 1472.9 L

Answer:

Empirical formula is C₃H₄O

Explanation:

Empirical formula:

It is the simplest formula gives the ratio of atoms of different elements in small whole number .

Given data:

Percentage of hydrogen = 7.14%

Percentage of carbon = 64.3%

Percentage of oxygen = 28.6%

Empirical formula = ?

Solution:

Number of gram atoms of H = 7.14 / 1.01 = 7.1

Number of gram atoms of O = 28.6 / 16 = 1.8

Number of gram atoms of C = 64.3 / 12 = 5.4

Atomic ratio:

            C                  :         H            :         O

         5.4/1.8             :      7.1/1.8       :       1.8/1.8

            3                   :        4            :        1

C : H : O = 3 : 4 : 1

Empirical formula is C₃H₄O.

Mass of water : 0.45 g

Given

1.5 g ethanoic acid

Required

Mass of water

Solution

Reaction

CH₃COOH + NaOH ⇒H₂O + CH₃COONa

mol CH₃COOH(MW=60 g/mol) :

= mass : MW

= 1.5 : 60

= 0.025

mol H₂O from the equation :

= 0.025(mol ratio CH₃COOH : H₂O= 1 : 1)

Mass of water :

= mol x MW water

= 0.025 x 18 g/mol

= 0.45 g

The area is important for climate science research because they can look at the glaciers and see over the years what is happening with them, are they multiplying or are they decreasing and if so at what rate.

Answer:

Melting glaciers are causing sea levels to rise. It’s important to study natural conditions in the Northern Patagonian Ice Field because the landscape there is dynamic and the effects of climate change can easily be seen. The retreat of the Nef Glacier and the disappearance of icebergs on the lake are evidence of rising temperatures and climate change.

Some of the properties are:

1. Gamma, γ-rays are not deflected by electric and magnetic fields. It shows that they do not have any charge.

2. Gamma, γ-rays are electromagnetic waves like X-rays. The wavelength of γ-ray photon is smaller than that of X-rays.

3. The rest mass of a Gamma, γ-ray photon is zero. (Photon has mass zero but it has momentum, why?)

4. Gamma, γ-rays travel with the speed of light.

5. Gamma, γ-rays have very large penetrating power. They can pass through several centimeter of iron and lead.

6. Gamma, γ-rays can produce fluorescene in a substance like willimite.
