Answer: Na-F has the highest electronegativity difference.

Explanation: Electronegativity is the measure of how strongle an atom holds the electrons. The highest electronegative atom is Fluorine.

Electronegativity of Sodium = 0.93

Electronegativity of Calcium = 1

Electronegativity of Hydrogen = 2.1

Electronegativity of Carbon = 2.55

Electronegativity of Fluorine = 3.98

Electronegativity difference in the following compounds:

Electronegativity difference in Na-F = 3.98 - 0.93 = 3.05

Electronegativity difference in Ca-F = 3.98 - 1 = 2.98

Electronegativity difference in H-F = 3.98 - 2.1 = 1.88

Electronegativity difference in C-F = 3.98 - 2.55 = 1.43

Electronegativity difference in F-F = 3.98 - 3.98 = 0

From the above calculations, it is visible that the highest electronegativity difference is present in Na-F.

From all the compounds, it is clearly seen that sodium can loose the electrons easily and is most electropositive and fluorine is the most electronegative element.

The answer is Na-F. The F has highest electronegativity among these elements. So we need to find the element with smallest electronegativity. And this element is Na.

Answer:

In fact, it turns out that the mass of an electron is so small relative to the masses of protons and neutrons that electrons are considered to have a negligible effect on the overall mass of an atom.

2Fe(s) +3H2SO4(aq) →Fe2(SO4)3(aq) +3H2(g)When 10.3 g of iron are reacted with 14.8 moles of sulfuric acid, what is the percent y

Elden [556K]

Answer:

1040%

Explanation:

To solve this question we must convert the mass of Iron to moles in order to find limiting reactant. With limiting reactant we can find the theoretical moles of hydrogen and theoretical mass:

Percent yield = Actual yield (5.40g) / Theoretical yield * 100

Moles Fe -Molar mass: 55.845g/mol-:

10.3g * (1mol / 55.845g) = 0.184 moles of Fe will react.

For a complete reaction of these moles there are necessaries:

0.184 moles Fe* ( 3 mol H2SO4 / 2 mol Fe) = 0.277 moles H2SO4.

As there are 14.8 moles of the acid, Fe is limiting reasctant.

The moles of H2 produced are:

0.184 moles Fe* ( 3 mol H2 / 2 mol Fe) = 0.277 moles H2

The mass is:

0.277 moles H2 * (2.016g/mol) = 0.558g H2

Percent yield is:

5.40g / 0.558g * 100 = 1040%

It is possible the experiment wasn't performed correctly
