AveGali [126]

Answer:An iodide ion is the ion I−. Compounds with iodine in formal oxidation state −1 are called iodides. This page is for the iodide ion and its salts, not organo iodine compounds. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.

Under the same conditions of temperature and pressure, which of the following gases would behave most like an ideal gas?Ne, N₂,
malfutka [58]

Answer:

Ne

Explanation:

Atomic number of Ne is 10.

Electronic configuration of Ne:

1s^2 2s^2 2p^6

Octet of Ne is complete . Element having complete octet are stable and behave ideal gas.

N_2 and CH_4 are reactive and hence, does not behave as ideal gas.

2. When carbohydrates are oxidized, the C-H bonds of the carbohydrate become C=O bonds of carbon dioxide. Oxidation is defined a
Flauer [41]

Answer:

A) The shared electrons in C-O bonds spend less time close to the carbon nucleus than the shared electrons in C-H bonds.

Explanation:

The electronegativity from H is 2.2, from C is 2.55 and from O is 3.44. This property is the measure of the attractive force between an atom and a pair of electrons.

So, the difference of electronegativity of H and C is smaller than the difference between O and C. Because oxygen is more electronegative, the electrons stay close to it in the bond C=O. So carbon has a partial positive charge in that bond. For the bond C-H, the shared electrons stay closes to carbon.

One of the pieces of evidence supporting energy quantization was the line spectra of elements. Why does this demonstrate energy
bezimeni [28]

Answer:

c) There are sharp emission lines demonstrating discrete energy levels.

Explanation:

When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.

On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.

The correct option is:

<u>c) There are sharp emission lines demonstrating discrete energy levels.</u>
