Answer: Option (1) is the correct answer.

Explanation:

A bond formed by transfer of electrons from one atom to another is known as an ionic bond.

Generally, an ionic bond is formed between a metal and a non-metal.

When a bond is formed by sharing of electrons then it is known as a coavlent bond.

A covalent bond is formed only within non-metals.

Chemical formula of iron(III) oxide is $Fe_{2}O_{3}$ . Here, iron is the metal and oxygen atom is the non-metal.

Hence, bond formed within both the elements will be ionic in nature due to transfer of electrons from iron to oxygen atom.

Thus, we can conclude that the bonds in iron(III) oxide are more ionic.

Which of the following statements is not correct?

Pavlova-9 [17]

Answer: This option is incorrect: <span>B. Covalent compounds are held together by much stronger interparticle forces than are ionic compounds.

Justification:

Ionic bonds, held by ionic compounds, are much stronger than covalent bonds, held by covalent compounds.

In ionic bonds one element yields one or more electrons forming a cation (a positively charged ion) and the other element accepts the electrons forming an anion (a negatively charged ion).

The anion and the cation are electrostatically atracted by each other. This electrostatic atraction force, named ionic bond, is very strong.

As result of this, the ionic compounds form strong crystals with high boiling and fusion points. A good example of this the sodium chloride, formed by the union of cation Na(+) and anion Cl(-).

The covalent bonds are result of sharing electrons and do not form ions. This bond is weaker than the ionic bond.

Delta S reaction= Delta S products- Delta S reactants

don't forget to mulitiply by coefficients

also

here is a really slow way to do it

you know the moles of gas increased

so Delta S is positive

so its B or D

then just do the units digit to see which one match up

What is the volume in liters of 321 g of liquid with a density of 0.84 g/mL

Rasek [7]

Density is weight by volume.

First. If you divide the weight by density you can find the volume

Second you must convert the ML in to Liters.

$\frac{321 \frac{g}{1}}{0.84 \frac{g}{mL}} = \frac{321(g)(mL)}{0.84g}=\frac{321mL}{0.84}=382.14mL$

1L=1000ml

$\frac{1L}{1000mL}$

$(382.14mL)( \frac{1L}{1000mL})= \frac{(382.14mL)(L)}{1000mL} =\frac{382.14L}{1000}=0.38214L$

0.38214 Liters.
