How many formula units are there in 2.45 moles potassium chloride?
To determine the number of formula units in 2.45 moles of potassium chloride, you first need to find the molar mass of KCl, which is approximately 74.55 g/mol. Then, divide the number of moles by the molar mass to get the number of formula units. Therefore, 2.45 moles of KCl is equivalent to about 163 formula units.
How cold is negative 163 celsius?
Negative 163 degrees Celsius is extremely cold. It is well below freezing and is even colder than the average temperature of Antarctica during winter. At this temperature, most substances will be frozen solid.
What is unsymmetrical dimethylhydrazine?
Dimethylhydrazine (DMH) has the chemical formula C2H8N2, but that's only part of the story, as you might have guessed. There is a symmetrical and an unsymmetrical "version" of this chemical compound. Let's start with the middle of the compound: N-N That's the pair of nitrogen atoms with a single bond between them. Now we have to deal with the pair of bonds on each nitrogen atom. There is a CH3 and a CH3 and H and H to add to the "mix" here. It's simple from here on out. In UDMH, unsymmetrical dimethylhydrazine (1,1 dimethylhydrazine), the H and the H are bonded to the "end" of one nitrogen atom, and the CH3 and the CH3 are bonded to the "end" of the other nitrogen atom. It's unsymmetrical because the H's are both on one end, and the CH3's are both on the other end. It might look something like this: HH N-N CH3CH3 The unsymmetrical dimethylhydrazine finds use as a component of rocket fuel. But you have to keep this stuff capped to isolate it from air 'cause it likes to take up the moisture in it, and the O2 and CO2 as well. These dilute its effectiveness as a propellant. It's fairly stable, and cannot be set off by shock, but it's volitile, as you might have guessed. In symmetrical dimethylhydrazine (1,2 dimethylhydrazine), H and CH3 are on one outside, and CH3 and H are on the other outside. Note that the H's and the CH3's are on opposite "corners" of the molecule. If you look at the thing, it might look like this: CH3H N-N HCH3 This particularly nasty compound is a powerful carcinogen, and it is used to induce tumors in animals for research purposes. UDMH has roots in hydrazine (N2H4), which has been known for quite a while (since the late 1800's). It was incorporated in the earliest rocket fuels, but UDMH rapidly replaced it for the most part. It is certain that the Natzi war machine used it, and the Me 163 Komet is an example of a user of hydrazine fuel. UDMH might be viewed as at "take off" from hydrazine.

What is the dot diagram for lithium nitride?
Aluminum nitride has the chemical formula of AlN. It is an ionic compound, so the dot structure begins with Al 3+ + [N] 3-. The N atom then has a pair of dots on each side to show the filled outer structure.

Fluorine is 18.99 and atomic number is 9?
The atomic number of fluorine is 9, which indicates the number of protons in its nucleus. The atomic mass of fluorine is approximately 18.99 atomic mass units, which is the average mass of an atom of fluorine taking into account its isotopes.
How many moles of Al(CN)3 are in 163 grams of the compound?
To find the number of moles of Al(CN)3 in 163 grams, you need to first calculate the molar mass of Al(CN)3. The molar mass of Al = 26.98 g/mol, C = 12.01 g/mol, N = 14.01 g/mol. Add these together with the appropriate subscripts for the compound to get the molar mass of Al(CN)3. Then, divide the given mass (163 g) by the molar mass to find the number of moles.
