Answer:

294.87 gm  CaCl_2

Explanation:

The computation of the  mass of calcium chloride is shown below:

But before that following calculations need to be done

Number of moles of chlorine atom is

= 3.20 × 10^24 ÷ 6.022 × 10^23

= 5.314 moles

As we know that

1 mole CaCl_2 have the 2 moles of chlorine atoms

Now 5.341 mole chloride atoms would be

= 1 ÷ 2 × 5.314

= 2.657 moles

Now

Mass of CaCl_2 = Number of moles × molar mass of  CaCl_2

= 2.657 moles × 110.98 g/mol

= 294.87 gm  CaCl_2

Answer:

C. 1.2 x 10^-11

Explanation:

pOH = 14 - pH = 14 - 3.08 = 10.92

[OH-] = 10^-pOH = 10^-10.92 = 1.2 x 10^-11

Answer:

See explanation

Explanation:

Energy of the photon (E) = 328 * 10^3/6.02 * 10^23 = 5.45 * 10^-19 J

Recall that E = hc/λ

h = Plank's constant = 6.36 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = ??

λ = hc/E

λ = 6.36 * 10^-34 * 3 * 10^8/5.45 * 10^-19

λ = 3.5 * 10^-7 m

This falls into the UV region of the spectrum

Answer:

hello the options related to your question is missing attached below is the complete question with the options

answer:

Any visible bands were found in the small area above the wells instead in the expected large bottom area of the gel, because Amanda should have placed the wells into the black (-) end of the chamber for DNA to move towards the opposite red (+) end of the gel.   (  2 )

Explanation:

Why Amanda did not see any bands in the region that she was expecting is because during electrophoresis ( which allows the distinguishing of various lengths of DNA fragments on a gel )  the DNA been negative will migrate to the positively charged  electrodes and  The shorter brands will move faster through the gel, providing DNA fragments arrangements on the gel according to size.

Answer:

The reactionnis known as a decomposition reaction

The equation of the reaction is given below as:

H₂CO₃ -----> H₂O + CO₂

Explanation:

A reaction in which a single compound is split into two or more simpler substances is known as a decomposition reaction.

In the reaction in which when a soda can is opened and left to the environment, the fizz in the soda, carbonic acid, separates into water and carbon dioxide is an example of a decomposition reaction.

The equation of the reaction is given below:

H₂CO₃ -----> H₂O + CO₂

In the reaction above, a larger molecular weight compound, carbonic acid with the molecular, H₂CO₃ is splits into two simpler substances of smaller molecular weight, water, H₂O and carbon dioxide, CO₂.

This reaction rate is made faster by an increase in temperature and by a decrease in pressure of the soda.

Answer:

The temperature is "298.51 K".

Explanation:

The given values are:

Density of ammonia,

d = 0.812 g/L

Pressure,

P = 1.17 atm

Mass:

M = [tex]NH_3[/tex]

   = [tex]14+ 1\times 3[/tex]

   = [tex]17[/tex]

As we know,

⇒ [tex]PV=nRT[/tex]

∴  [tex]T=\frac{PV}{nR}[/tex]

       [tex]=\frac{PV}{\frac{W}{M}\times R }[/tex]

       [tex]=\frac{PVM}{W\times R}[/tex]

By putting the value of "W", get

       [tex]=\frac{PVM}{V\times d\times R}[/tex]

       [tex]=\frac{P\times M}{d\times R}[/tex]

On substituting the values in the above equation, we get

       [tex]=\frac{1.17\times 17}{0.812\times 0.08205}[/tex]

       [tex]=\frac{19.89}{0.06699}[/tex]

The number of moles of silver atoms in the piece of jewelry is 0.08784 moles

Here is the complete question:

Suppose a piece of jewelry contains 5.29 × 10²² atoms of silver  . How many moles of silver atoms are in the piece of jewelry?

From the question,

A piece of jewelry contains 5.29 × 10²² atoms of silver.

To determine number of moles of silver atoms in the piece of jewelry,

We will use the formula

[tex]Number \ of \ moles = \frac{Number \ of \ atoms }{Avogadro's \ number}[/tex]

From the question

Number of atoms of silver = 5.29 × 10²² atoms

and

Avogadro's number = 6.022 × 10²³ atoms/mole

∴ [tex]Number \ of \ moles \ of \ silver \ atoms= \frac{5.29 \times 10^{22} }{ 6.022 \times 10^{23} }[/tex]

Number of moles of silver atoms = 0.08784 moles

Hence, the number of moles of silver atoms in the piece of jewelry is 0.08784 moles

Answer:

The wavelength for the transition from n = 4 to n = 2 is 486nm and the name  name given to the spectroscopic series belongs to The Balmer series.

Explanation

lets calculate -

Rydberg equation-   [tex]\frac{1}{\pi } =R(\frac{1}{n_1^2} -\frac{1}{n_2^2})[/tex]

where ,[tex]\pi[/tex] is wavelength , R is Rydberg constant ( [tex]1.097\times10^7[/tex]), [tex]n_1[/tex] and [tex]n_2[/tex]are the quantum numbers of the energy levels. (where [tex]n_1=2 , n_2=4[/tex])

Now putting the given values in the equation,

                [tex]\frac{1}{\pi }=1.097\times10^7\times(\frac{1}{2^2} -\frac{1}{4^2} )[/tex][tex]=2056875m^-^1[/tex]

    Wavelength [tex]\pi =\frac{1}{2056875}[/tex]

             =[tex]4.86\times10^-^7[/tex] = 486nm

   Therefore , the wavelength is 486nm and it belongs to The Balmer series.

Answer: Scientists use the term bioenergetics to describe the concept of energy flow (Figure 4.2) through living systems, such as cells. Cellular processes such as the building and breaking down of complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Just as living things must continually consume food to replenish their energy supplies, cells must continually produce more energy to replenish that used by the many energy-requiring chemical reactions that constantly take place. Together, all of the chemical reactions that take place inside cells, including those that consume or generate energy, are referred to as the cell’s metabolism.

Answer:

here you go. I took the test :)

Explanation:

Answer:

Explanation:

a) The forward reaction is exothermic, hence when temperature is increased the equilibrium shift towards the reactants side to get rid of the excess energy. This will mean that more reactants are produced decreasing yield

b) There are a fewer number of moles of gas on the right side compared to the left side (Just count the coefficients before each compound) so a higher pressure will mean that the equilibrium will shift towards the products side in order to decrease the pressure. This will mean that more products are formed increasing yield

c) When something is powdered it's surface area to volume ratio increases. A higher surface area means that the particles around it have more area to work on so the frequency of collisions will increase increasing the rate of reaction. This is why iron is powdered.
