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.

Which reaction is an example of an acid-base reaction? Which reaction is an example of an acid-base reaction?
oksian1 [2.3K]

Answer:

B) H2SO4 (aq) + Ca(OH)2 (aq) → CaSO4 (aq) + 2 H2O(l)

Explanation:

A is a reaction between a salt FeCl3 and a base KOH

C is a n acid decomposing on it's own to form two products

D is mercury, a metal reacting with oxygen. Two elements reacting. Neither are an acid or a base

E. is an acid reacting with a metal to liberate hydrogen. There is no base

Calculate the number of moles in 7g of nitrogen gas​
Andru [333]

Answer:

<h3>0.2498molN_{2}</h3>

Explanation:

7gN2 x \frac{1 mol}{2(14.01) g}

=0.2498mol N2

Nitrogen gas has the formula N_{2} so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).
