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

Which of the following would be most useful in trying to obtain procedural information to replicate an experiment previously pub

Anit [1.1K]

Answer:

Peer-reviewed Journal Article

Explanation:

1.Dictionary

2.Encyclopidia

3.Internet Search Engine

4.Peer-reviewed Journal Article

The correct answer as to which would be most useful in trying to obtain procedural information to replicate an experiment previously published would be a peer-reviewed journal article.

A peer-reviewed journal article is a journal article written by an expert or experts on a particular topic and has undergone thorough reviews by experts in the same field and certified to be of good-enough standards to be published.

Such an article would contain all the necessary information relating to the experiment leading to the article. Hence, in order to obtain procedural information to replicate an experiment that has been previously published, a peer-reviewed journal published on the same topic would do be the right place to seek.

How many oxygen atoms are in 6.90 g of Al2(SO4)3? Express your answer using scientific notation with two decimal places.

harkovskaia [24]

First, you need to know the molar mass of the compound. The compound Aluminum Sulfate has a molar mass of 342.15 g/mol. From the subscript of the compound, there are 4*3 = 12 moles of oxygen in 1 mole of the compound. The solution is as follows:

6.90 g Al₂(SO₄)₃*(1 mol/342.15 g)*(12 mol O/1 mol Al₂(SO₄)₃)*(6.022×10²³ atoms/mole) = 1.457×10²³ atoms of oxgyen

Consider the following reaction: C2H4(g) + H2O(g) ⇌ C2H5OH(g) ΔHo = -45.8 kJ/mol At 298K the equilibrium constant, KP, for this

Ber [7]

Answer:

ΔG = 2721.891 J/mol

Explanation:

C2H4(g) + H2O(g) ↔ C2H5OH(g)

∴ ΔH°rxn = - 45.8 KJ/mol

∴ Kp = 28.5

If p(C2H4) = p(H2O) = p(C2H5OH) = 3.0 atm ⇒ ΔG°rxn = ?

⇒ Kp = (PC2H5OH/P*) / (PC2H4/P*)(PH2O/P*)

∴ P* = 1 atm

⇒ Kp = (3 atm) / (3 atm)(3 atm) = 0.33

Kp = e∧( - ΔG/RT)

⇒ Ln Kp = - ΔG/RT

⇒ ΔG = - RT LnKp

∴ T = 298 K

∴ R = 8.314 J/mol.K

⇒ ΔG = - ((8.314 J/mol.K)(298 K)) Ln(0.33)

⇒ ΔG = 2721.891 J/mol
