The tetrachloride of carbon (
[url=http://en.wikipedia.org/wiki/Tetrachloromethane]Tetrachloromethane[/url]) is a colorless liquid with tetrahedral molecules, CCl4. Unlike most other non-metal chlorides, it is not hydrolysed by water or by alkalis. There are two explanations for this:
Explanation 1:
There are no d-orbitals in the second shell of the C atom. As a result, when a water molecule attacks a CCl4 molecule, the carbon atom does not have an empty orbital to accept the incoming electron pair.
The problem with this explanation is that it suggests that the hydrolysis of halogenoalkanes by a similar mechanism, should also be impossible.
Explanation 2:
The difference in behavior of CCl4 and SiCl4 with water is a result of the much smaller size of a carbon atom compared to a silicon atom. As a result, it is impossible for water molecules to attack a carbon atom when it is surrounded by four relatively large chlorine atoms in CCl4 and is strongly bonded to them.
Sodium chloride (NaCl) is definitely an inorganic compound. NB Organic compounds are the chemistry of CARBON compounds. Inorganic compounds is any other compound NOT containing carbon.
k,
I'm not a chemist, but I rather feel that you'd only be able to combine the Al and the Si. But on a little research, indeed a few of the silicides exist, including a Mg variant, which when mixed with HCl, produces a gas Silane, SiH4, the Si analog of Methane. But more reactive. Given that He is a noble gas, it may not combine.

analog
A synthetic analog is a: synthetically created compound that differs from the Natural compound Both in it's structure and function. Although probably very similar to the original compound.
Among other reasons, the Si-Si double bond is much more unfavorable in terms of energy compared to the Si-Si single bond than is the case with carbon.
Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
As compared to what? Are you talking analog cable or digital cable? Are you comparing it to an analog signal over the air or a satellite receiver?
A: An ADC will convert the analog to a digital value compared to a known analogue reference. Each digital output will represent a value in BCD form as bits to analog input

Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.

An agonist causes action while an analog just mimics another chemical compound. Agonist bind to and activate receptors and cause a biological response.
