Hello there.

How many is an octet of electron

Referring to the octet rule, atoms attempt to get a noble gas electron configuration, which is eight<span> valence electrons. Sodium has one valence electron, so giving it up would result in the same electron configuration as neon. Chlorine has seven valence electrons, so if it takes one it will have </span>eight<span> (an octet).</span>

To get this it helps to know the electronegativity numbers of the elements but it isn't required. You just need to know that Fluorine is the most electronegative element and that the farther away from Fluorine you are on the periodic table, the less electronegative you get.  The one exception to this rule is hydrogen with actually has an electronegativity of 2.1 while lithium has one of 1.0.  Also the higher difference in electronegativity between two atoms the more polar the bond is.  

Now to start the question.  H-Br could be a contender since H has an electronegativity number of 2.1 and Br is relatively close to Fluorine so we'll put that one aside for now.  H-Cl knocks out A because both bonds have H but one bond has Br and the other has Cl.  Cl is closer to Fluorine than Br so answer B is the contender now.  For answer C, I and Br are too close to have a higher electronegativity difference than H-Cl so that one isn't it.  Finally for answer D, I is much closer to Cl than H is so the electronegativity difference is much less, making your answer B.

The correct equation for the overall reaction can simply be obtained by adding the two separate equations together. Now when you add the two equations together, the overall K can be calculated by multiplying the individual K values. Therefore:<span>

K(overall) = K1 * K2 </span>

K(overall) = (1.6 x 10^-10) * (1.5 x 10^7)

<span>K(overall) = 2.4 x 10^-3</span>

What will you observe if you add cuso4 to a solution containing glucose?
arsen [322]
The blue color of copper (ii) sulfate will change to green, yellow, orange ,red and then a dark red or brown.
Glucose is a reducing sugar; reducing sugars are sugar that forms an aldehyde or ketone in the presence of an alkaline solution. Reducing sugars reduce the blue copper sulfate from the Benedict's solution to a red brown copper sulfide; which is seen as the precipitate and is responsible for the color change.
