lina2011 [118]
<h2>Answer:</h2>

The transferred energy by the energy will be converted into the kinetic energy of molecules. Which allow them to move more fastly then in solid.

<h3>Explanation:</h3>

In solid, molecule are moving but their motion is vibrational motion. They don't change their position. It means their kinetic energy is that much low to let them move freely.

But in case of liquid, molecules have much energy to move freely in the matter. Their bonds don't break, so the will be in liquid form.

This increase in kinetic energy is due to energy given by the internee.

A polar bond is formed with atoms having different electronegativities. The bonding electrons are attracted more towards the atom with greater electronegativity resulting in unequal sharing of electrons. Therefore the molecule develop partial charges and becomes polar. Polar molecules have dipole moment that is the partial charge on molecules due to differences in electronegativity between atoms.

A non-polar bond is formed with atoms having the same electronegativity, hence the bonded pair of electron is shared equally between atoms. Non-polar molecules have no moment.
Note that: symmetrical molecules having polar bonds are non-polar because the dipoles of the bond exert equal and opposite effect. Hence the dipoles cancel the charges.

Example: HCl
In HCl, Cl is more electronegative therefore Cl atom pulls the electron pair of the covalent bond towards itself and develops a partial negative charge. Consequently H develops a partial positive charge. This therfore leads to the formation of a dipole.

How does particles of substance behave at its melting point?
ivolga24 [154]

<span>When a substance is heated, its atoms gain energy and begin to vibrate rapidly within the lattice of the substance (the substance expands). As more heating continues, the atoms gain even more energy and move more rapidly until they are able to overcome the force of the bonds, that hold the atoms together in the lattice, until the structure is disrupted.  </span>

Stochiometry .How many grams of CO2 is produced when excess CS2 reacts with 4 mols of O2? CS2+O2-SO2 Please balance equation.
Travka [436]

Mass of CO₂ produced : 58.67 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

CS₂ + 3O₂  -------> CO₂ + 2SO₂

mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)

From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂  :

\tt \dfrac{1}{3}\times 4=\dfrac{4}{3}

mass  CO₂ (MW= 44 g/mol) :

\tt \dfrac{4}{3}\times 44=58.67~g
