Determine the identity of the daughter nuclide from the electron capture by 3517cl. determine the identity of the daughter nucli
brilliants [131]

Answer:

  •           ^{35}_{16}S

Explanation:

When the nucleus of an <em>atom captures and electron</em>, such electron combines with a proton and forms a neutron. Thus, the mass number remains the same (just a proton has been converted into a neutron) but the atomic number (the number of protons) decrease in one.

Then, the daughter nuclide will have the same mass number and the atomic number reduced in one.

The given parent isotope is    ^{35}_{17}Cl,    which means that it has these features:

  • Chemical symbol: Cl
  • Name of the element: chlorine
  •  Mass number (the superscript to the left): 35
  •  Atomic number (the subscript to the left): 17

And the daughter nuclide after the electron capture will be:

  • Mass number: 35 (the same of the parent nuclide)
  • Atomic number: 17 - 1 = 16
  • Identity: sulfur (search the element with atomic number 16 in a periodic table).
  • Chemical symbol: S

  • Idenity of the daughter nuclide using the isotope notation:

          ^{35}_{16}S

Hence, the answer is the third choice.

Which scenario best exemplifies the way a signal is passed down an axon coated with myelin sheath?
goblinko [34]

Runners sprinting short distances in a relay race and handing off a baton scenario best exemplify the way a signal is passed down an axon coated with a myelin sheath.

Axons are long extensions of neurons (or nerve cells) involved in the transmission of nerve impulses away from the cell body. Each nerve cell has an axon that is over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the ends of the axon.

Each neuron in the brain has long cables that meander from the body of the cell. These cables, several times thinner than human hair, are called axons and are where electrical impulses leave neurons and are received by other neurons.

HNO3 + S --&gt; H2SO4 + NO Now identify the element oxidized and the element reduced. Which element is oxidized? Which element i
OleMash [197]

<u>Answer:</u> S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction

<u>Explanation:</u>

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when oxidation number of a species decreases.

For the given chemical reaction:

HNO_3+S\rightarrow H_2SO_4+NO

<u>On the reactant side:</u>

Oxidation number of H = +1

Oxidation number of N = +5

Oxidation number of O = -2

Oxidation number of S = 0

<u>On the product side:</u>

Oxidation number of H = +1

Oxidation number of N = +2

Oxidation number of O = -2

Oxidation number of S = +6

As the oxidation number of S is increasing from 0 to +6. Thus, it is getting oxidized. Similarly, the oxidation number of N is decreasing from +5 to +2. Thus, it is getting reduced.

The oxidation numbers of O and H remain the same on both sides of the reaction. Thus, they are neither getting oxidized or reduced.

Hence, S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction
