Please help! Each color of.light has a specific amount of energy. A
hydrogen atom will absorb and emit red, blue-green, blue, and violet light but not
yellow or orange light. Explain this phenomenon

Answers

Answer 1

Answer:

only certain wavelengths of the light can be absorbed.

Answer 2

There are no transitions in the hydrogen atom that corresponds to the wavelength of yellow or orange light.

Each color corresponds to a particular wavelength. The wavelengths that are observed for a given atom depends on the transitions that are possible for electrons of the atom.

In the hydrogen atom, there is no transition whose wavelength corresponds to the wavelength of yellow or orange light. None of the lines in the hydrogen spectrum has such wavelength.

For instance, yellow light corresponds to 590 nm - 560 nm but this wavelength is missing from the spectrum of hydrogen(crosscheck in the image attached).

As such, we do not see yellow or orange lights in the hydrogen spectrum.

What is the final temperature of a 5.0g sample of water at 25C If 832 joules of heat are added?

Answers

Answer:

64.71C

Explanation:

Given

Mass (m) = 5g

Initial Temperature (T1) = 25C

Heat (Q) = 832 joules

Required

Determine the final temperature

This question will be solved using:

Q = mc∆T

Where c = specific heat = 4.19

Substitute values in the above formula, we have:

832 = 5 * 4.19 * (T2 - 25)

832 = 20.95 * (T2 - 25)

Divide both sides by 20.95

39.71 = T2 - 25

Add 25 to both sides

39.71 + 25 = T2

T2 = 64.71C

a. Using this information, draw the structure of the tertiary butyl radical that will form upon removal of a hydrogen atom.
b. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars.

Answers

Answer:

Explanation:

Butane is an alkane with the molecular formula C₄H₁₀.

(a) It has two structural isomers (n-butane and 2-methylpropane) shown below

     H   H   H   H

      |     |     |     |

H - C - C - C - C - H

      |     |     |     |

     H   H   H   H

The structure above is n-butane

     H     CH₃ H

      |       |       |

H - C  -  C  -  C - H

     |       |       |

    H     H     H

The structure above is 2-methylpropane and can also be referred to be a tertiary butane because the central carbon atom has 3 methyl groups attached to it as shown below.

        CH₃

         |

Percent yield of reaction is 75%.

Explanation:

Given data:

Moles of A = 2.0 mol

Moles of B = 4.0 mol

Moles of C formed = 1.8 mol

Percent yield of reaction = ?

Solution:

Chemical equation:

2A + 5B     →      3C +  D

We will compare the moles of A and B with C from balance chemical equation.

                A         :          C

                2         :           3

               B          :         C

                 5         :         3

                 4         :        3/5×4 = 2.4 mol

Number of moles of C formed by 4 moles B are less thus B is limiting reactant and will limit the yield of C.

Percent yield:

Percent yield =  actual yield /theoretical yield × 100

Percent yield = 1.8 mol / 2.4  × 100

Percent yield =75%

Answer:

Zero grams of NaCl & KNO₃  ... The reagents mixed in aqueous solution would not produce products as no driving force is present; i.e., no precipitate, weak electrolyte or gas decomposition product will form.

Explanation:

NaNO₃(aq) + KCl(aq) => (theoritically) NaCl(aq) + KNO₃(aq)

However all chloride salts from metathesis rxns remain soluble and 100% ionized except for halide derivatives of Hg⁺², Ag⁺ & Pb⁺₂.  Further, all NO₃⁻ salt derivatives also remain soluble and 100% ionized.

Technically, metathesis reactions (also known as double replacement rxns) depend upon the formation of a 'driving force' that leaves the reaction system in the form of a precipitate, weak electrolyte (weak acid or weak base) or a gas decomposition product. So, the reaction in this case should be as follows:

NaNO₃(aq) + KCl(aq) => No Reaction

Describe the flow of energy through an ecosystem from the Sun to the plant and ultimately through an animal.

Answers

Answer:

Hope this Helps! :)

Explanation:

The word ecosystem refers to the all of the living species as well as non-living elements in a particular environmental area. For instance, a lake, swamp, coral reef, forest, or a prairie would each be considered an ecosystem. Ecosystems can vary greatly in size and individual characteristics -- for instance, the ecosystem of a puddle differs greatly from that of a swath of tundra.  

Despite these disparities, all ecosystems function similarly in the way in which energy flows into, through, and out of them through the energy cycle

Energy is transferred into and out of ecosystems via a web of complex interactions. Energy enters an ecosystem from external sources and moves throughout its components. For instance, energy from the sun flows through plants, microorganisms, and animals. Energy cycles in an ecosystem end with decomposition, and then the process begins anew    

Essentially, the flow of energy through ecosystems can be explained by who eats what. Keep in mind, however, that energy transfer isn’t perfectly efficient; much of it dissipates as heat at various phases in the cycle.

The energy flows from the sun to the plants by photosynthesis and animal eats plants and energy is transferred from plants to animals.

What is the transfer of energy?

The energy transfer isn't entirely efficient because a significant amount of it evaporates as heat at different points throughout the cycle.

Despite these differences of energy, all ecosystems function similarly in terms of the energy cycle, which governs how energy enters, passes through, and exits them.

Ecosystems receive and expend energy through a network of intricate interconnections. An ecosystem receives energy from outside sources, which circulates among its parts.

Thus, as a result of photosynthesis, energy is transmitted from the sun to plants, which are then consumed by animals.

A reaction of chlorine gas with sodium solid creates 45.6 grams of sodium chloride. The mass of sodium and chlorine gas price for the reaction was ___ grams​

Answers

Answer:

17.94 annd 27.69 respectively.

Explanation:

Na(s) + Cl(g) n` NaCl(s)

mass of NaCl = 45.6 g

Mr of NaCl = 23 + 35.5

= 58.5g/mol

mole of NaCl = mass/Mr

= 45.6/58.5

= 0.78 moles

From the equation;

1 mole of NaCl = 1 mole of Na = 1 mole of Cl

hence 0.78 mol of NaCl = 0.78 mol of Na = 0.78 mol of Cl.

mass of Na = 0.78 × 23

= 17.94 grams

mass of Cl = 0.78 × 35.5

= 27.69 grams

The mass of the sodium and chlorine gas taken for the reaction was  17.92 grams and 27.73 grams​ respectively.

What is sodium chloride?

Sodium chloride is an ionic compound in which the sodium (Na⁺) and chloride (Cl⁻) ions are present in a ratio of 1 : 1. It is commonly known as table salt or halite.

Sodium and chlorine react with each other to generate a substance that is familiar to everybody around the globe which is sodium chloride.

2Na (s)   +   Cl₂ (g)   [tex]\longrightarrow[/tex]    2NaCl (s)

The atomic mass of the sodium (Na) = 23 g/mol

The atomic mass of chlorine,(Cl) = 35.5 g/mol

The molar mass of the sodium chloride (NaCl) = 58.5 g/mol

Given, the mass of the NaCl formed = 45.6 g

If 117 g NaCl formed from sodium = 2× 23 g

Then 45.6 NaCl will be formed from Na = 17.92 g

If 117 g NaCl formed from chlorine = 2× 35.5 g

45.6 NaCl will be formed from chlorine = 2× 35.5 ×45.7/117 = 27.73 g
