Answer:

Fluorescent luminaire is the assembly that forms a lamp, called a fluorescent tube, and an armature, which contains the accessories necessary for operation. In certain places, only the lamp is known as a luminaire. The lamp is low pressure mercury vapor discharge and is normally used for domestic or industrial lighting. Its advantage over other types of lamps, such as incandescent lamps, is their energy efficiency.

The lamp consists of a thin glass tube lined internally with various compound chemicals called phosphors, although they generally do not contain the chemical element phosphorus and should not be confused with it. Those chemical compounds emit visible light when receiving ultraviolet radiation. The tube also contains a small amount of mercury vapor and an inert gas, usually argon or neon, at a pressure lower than atmospheric pressure. At each end of the tube is a filament ...

What is the correct formula for the compound formed between sodium and iodine based on their positions in the periodic table?
Naddika [18.5K]
Sodium (Na) has a +1 charge and Iodine ( I ) has a -1 charge. To create a molecule of sodium iodide the charges will need to balance.

Because the charges on anion and cation are the same; the molecular formula will be NaI

Boron has two naturally-ocurring isotopes. Boron-10 has an abundance of 19.8% and actual mass of 10.013 amu, and boron-11 has an
aniked [119]

Answer:

Average atomic mass = 10.812 amu

Explanation:

The formula for the calculation of the average atomic mass is:

Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})

Given that:

<u>For first isotope, Boron-10: </u>

% = 19.8 %

Mass = 10.013 amu

<u>For second isotope, Boron-11: </u>

% = 80.2 %

Mass = 11.009 amu

Thus,  

Average\ atomic\ mass=\frac{19.8}{100}\times {10.013}+\frac{80.2}{100}\times {11.009}=1.982574+8.829218=10.811792

<u>Average atomic mass = 10.812 amu</u>

Model 1-How is a cell like a factory
anastassius [24]

A cell is like a factory in many ways.

For one, the cell typically contains many organelles that have several varying functions. In a factory, you have many workers who perform different tasks, just as the organelles in the cell do.

Another reason is that cells contain a nucleus or the boss/brain of the cell. In factories, this could be considered the boss of the workplace that tells each and every worker, or organelle, what to do.

The selectively permeable membrane of a cell also resembles a factory as it only lets in workers or special guests. The cell's membrane only lets in specific materials, hence the selectively permeable membrane.

These are just a few ways as to how the cell is like a factory.

Hope this helps!

What is the electron configuration of an electrically neutral alkaline earth metal? please explain​
vlabodo [156]

Answer:

The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns
