Answer:

Yes

Explanation:

Electronegativity is the tendency for atoms to keep electrons closer to them. So, if the atoms are smaller there, there is a stronger pull on the electrons to keep them closer. So, the larger the atom get, due to electron shielding, it become less electro negative. I hope this help. You might get a better explanation from Khan Academy's video on Electronegativity

Answer:

A relationship is intuitively expected

Does electronegativity relate to atomic radius? A relationship is intuitively expected between electronegativity and radius: the size of an atom is determined by the distribution of electrons around its nucleus. The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.

Use bond energies to determine Î´hrxn for the reaction between ethanol and hydrogen chloride. ch3ch2oh(g)+hcl(g)âch3ch2cl(g)+h2o

Alex

For this reaction to proceed, the following bond breaking should occur:
*one C-O bond* one H-Cl bond
After, the following bond formations should occur:*one C-Cl bond*one O-H bond
Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.
ΔHrxn = (1)(358) + (1)(431) + 1(-328) + 1(-463) = -2 kJ

What is an ionic compound? How is electrical neutrality maintained in an ionic compound?

Alenkinab [10]

Answer: When oppositely charged species interact.

Explanation:

Ionic compound is defined as the compound which is formed by the complete transfer of electrons from one element to another element.

In these compounds, oppositely charged ions are attracted towards each other to form a compound.

For Example: NaCl is formed by the attraction of $Na^+\text{ and }Cl^-$ ions. So, same number of oppositely charges maintain electrical neutrality.

Electrical neutrality in a compound is achieved when atoms forming a compound have same number of opposite charges. Basically the charges on cation is balanced by the charges on anion.

How much volume would 0.450 mol CO2 gas occupy?

umka21 [38]

Answer:

10.08 L.

Explanation:

If we assume that CO₂ gas behaves ideally at STP (standard T(0.0 °C) and P(1.0 atm)):

It is known that 1.0 mole of ideal gas occupies 22.4 L at STP conditions.

Using cross multiplication:

1.0 mole of CO₂ gas occupies → 22.4 L.

0.45 mole of CO₂ gas occupies → ??? L.

∴ The volume occupied by 0.45 mole of CO₂ gas = (0.45 mol)(22.4 L)/(1.0 mol) = 10.08 L.
