If you were asked to covert 1.3 mol al to atoms which of the following should you use for the concersion

How many of the following molecules are polar? Pcl5 cos xeo3 sebr2

klasskru [66]

Answer:

Three (3) of the molecules are polar: $CoS,$ $XeO_{3},$ $SeBr_{2}$ .

Explanation:

Polar substances have their elements held together by a covalent bond that contain partially positive and negative charges, which results in a difference in the charges' electronegativity difference (usually ranging between 0.4 and 0.7).

PCl5 is non-polar with a symmetric geometry
CoS is polar
XeO3 is polar, with a trigonal pyramidal molecular geometric
SeBr2 is polar as the difference their electronegativity is about ).5

The difference between diffusion and osmosis is that osmosis deals only with ________.

Nat2105 [25]

Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 3.001 g sample of B

loris [4]

I believe here is the right question, so will just ignore the rest of the junk information from the previous message

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 3.001 g sample of BHT was combusted in an oxygen rich environment to produce 8.990 g of CO2(g) and 2.944 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT

Answer:

$C_{15}H_{24}0$

Explanation:

A 3.001 g sample of BHT was combusted in an oxygen rich environment to produce 8.990 g of CO2(g) and 2.994 g of H2O(g).

If all the carbon in BHT is present in $CO_2$ and also, all the hydrogen in BHT is present in $H_2O$ , Then we can determine for the corresponding numbers of moles of Carbon(C) and Hydrogen (H) respectively as:
