<span>Any number that is a multiple of 1.6 is correct, because you can't have a fraction of an electron. Obviously the first one is wrong, because it's charge is smaller than the charge of a single electron, implying that it has a fraction of an electron.
</span>( 1) -3.2x10^-19C 
<span>(2 ) -4.8x10^-19C </span>

diamong [38]
1 mole of gas occupies 22.4 L at STP. Therefore, each gas has 1/22.4 moles and because the number of moles is the same, the number of molecules of each gas is also the same.

The least polar molecules are of N₂ and they will show the most ideal behavior out of all three of the gases.

BF3 + Li2SO3 ---&gt; B2(SO3)3 + LiF. What is the coefficient of lithium fluoride in the balanced chemical reaction? A. 1 B. 2 C.
uranmaximum [27]
The unbalanced equation is BF3 + Li2 SO3 --> B2 (SO3)3 + LiF, where the numbers to the right of the symbols are subscripts. The balanced equation is 2 BF3 + 3 Li2SO3 ---> B2 (SO3)3 + 6LiF. The numbers in front of every formula (compound) are the respective coefficients. You can check that the equation is balanced counting every element: There are 2B in the side of the reactants and 2B in the side of the products; there are 6F in the side of the reactants and 6F in the side of the products; there are 6 Li in the side of the reactants and 6 Li in the side of the products; and there are 3 SO3 in the side of the reactants and 3 SO3 in the side of the products. <span>So, the coefficient of the LiF is 6.</span>

Each of the following names is wrong. Draw structures based on them, and correct the names:(b) 1,1,1-trimethylheptane
devlian [24]

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

<h3>IUPAC NAME:</h3>

It is systematic way of nomenclature of organic compounds.

It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.

The given compound is 1,1,1-trimethylheptane.

The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.

Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.

If the numbering is done according to the question, number of carbon atom in straight chain is 7.

Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
