Answer : The covalent compounds are, SiF₄, CO₂, S₇O₂, PCl₃, H₂O  and S₂F₁₀

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

KBr

It is an ionic compound because potassium element is a metal and bromine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

SiF₄

It is a covalent compound because sharing of electrons takes place between silicon and fluorine. Both the elements are non-metals and hence, will form covalent bond.

Al₂O₃

It is an ionic compound because aluminum element is a metal and oxygen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

CO₂

It is a covalent compound because sharing of electrons takes place between carbon and oxygen. Both the elements are non-metals and hence, will form covalent bond.

NaCO₃

It is an ionic compound because sodium element is a metal and carbon element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

S₇O₂

It is a covalent compound because sharing of electrons takes place between sulfur and oxygen. Both the elements are non-metals and hence, will form covalent bond.

PCl₃

It is a covalent compound because sharing of electrons takes place between phosphorus and chlorine. Both the elements are non-metals and hence, will form covalent bond.

Fe₃N₂

It is an ionic compound because iron element is a metal and nitrogen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

H₂O

It is a covalent compound because sharing of electrons takes place between hydrogen and oxygen. Both the elements are non-metals and hence, will form covalent bond.

S₂F₁₀

It is a covalent compound because sharing of electrons takes place between sulfur and fluorine. Both the elements are non-metals and hence, will form covalent bond.

Hence, the covalent compounds are, SiF₄, CO₂, S₇O₂, PCl₃, H₂O  and S₂F₁₀

What is the mass of 18.0 mL of honey if its' density is 1.42 g/mL?
BigorU [14]

mass (m) = ? , volume = 18.0 ml , density = 1.42 g/ml .

density =  \frac{mass}{volume}  \\  \\ d =  \frac{m}{v}  \\  \\ mass = density \times volume \\  \\ m = d \times v \\  \\ m = 18 \: ml \times  \: 1.42 \:  \frac{g}{ml}  \\  \\ m = 25.56 \: g

I hope I helped you^_^

Explain how lone pairs of electrons influence the shape of a molecule.
Ronch [10]

Explanation:

the lone pairs will be negatively charged. these have a repulsion effect on other negatively charged electrons in the shells of atoms. picture a water molecule: the lone electron pair on the top of the oxygen will have a repulsion force on the 2 hydrogen atom's orbiting electrons to cause a bent molecular geometry.

A solution of 2-propanol and 1-octanol behaves ideally. Calculate the chemical potential of 2-propanol in solution relative to t
andrew-mc [135]

Answer:

The chemical potential of 2-propanol in solution relative to that of pure 2-propanol is lower by 2.63x10⁻³.    

Explanation:

The chemical potential of 2-propanol in solution relative to that of pure 2-propanol can be calculated using the following equation:

\mu (l) = \mu ^{\circ} (l) + R*T*ln(x)

<u>Where:</u>

<em>μ (l): is the chemical potential of 2-propanol in solution    </em>

<em>μ° (l): is the chemical potential of pure 2-propanol   </em>

<em>R: is the gas constant = 8.314 J K⁻¹ mol⁻¹ </em>

<em>T: is the temperature = 82.3 °C = 355.3 K </em>

<em>x: is the mole fraction of 2-propanol = 0.41 </em>

\mu (l) = \mu ^{\circ} (l) + 8.314 \frac{J}{K*mol}*355.3 K*ln(0.41)

\mu (l) = \mu ^{\circ} (l) - 2.63 \cdot 10^{3} J*mol^{-1}

\mu (l) - \mu ^{\circ} (l) = - 2.63 \cdot 10^{3} J*mol^{-1}  

Therefore, the chemical potential of 2-propanol in solution relative to that of pure 2-propanol is lower by 2.63x10⁻³.    

I hope it helps you!
