Particles are arranged in a crystal structure in a sample of:a) H2 (g)
b) Br2 (L)
c) Ar (g)
d) Ag (s)

Answers

Answer 1
Answer: The answer is number 4. Ag(s) or Solid Silver. Silver in a solid phase has a face centered cubic crystal structure. Among your choices, silver is the only example of particles that are arranged in their crystal structure while the other choices are gases and liquid. Liquid and gases have loose atoms that do not form crystal structures.

To ensure accurate recall of the experimental data, at minimum one should

Answers

To ensure accurate recall of the experimental data, at minimum one should keep a record of the data of all the experiments done. Also, the date when it is recorded is important so as to support that the data is real and not only made up.

Answer:

record the data in writing

Explanation:

A liquid boils when its vapor pressure equals the pressure of the atmosphere.TRUE

FALSE

Answers

The answer is true. A liquid boils when its vapor pressure equals the pressure of the atmosphere. At this point, vapor can now readily escape from the liquid phase because it has an equal pressure now with its surrounding which, basically, is in the vapor phase.

Answer:

True

Explanation:

The boiling point of a liquid is the temperature at which the vapour pressure of the liquid equals the pressure of the surrounding atmosphere.

When a liquid is heated, the vapour pressure gradually increases till it matches the ambient pressure. Gas bubbles begin to form within the liquid, rise to the surface and then burst up to release gas. At this point, we say the liquid is boiling.

The lower the surrounding pressure, the lower the boiling point of a liquid and vice versa. Water boils at lower temperature in high altitudes because of lower pressure as compared to sea level.

Correct option: True.

Which compound has both ionic and covalent bonding?(1) CaCO3 (3) CH3OH
(2) CH2Cl2 (4) C6H12O6

Answers

The compound that has both ionic and covalent bonding is \boxed{\left( 1 \right){\text{ CaC}}{{\text{O}}_3}}.

Further Explanation:

The attraction between different atoms, molecules and ions is known as a chemical bond. The formation of various types of compounds takes place as a result of these chemical bonds.

An ionic bond is formed as a result of the interaction between a metal and a non-metal. Metals have the tendency to lose electrons while non-metals tend to gain electrons. Due to this, metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons.

A covalent bond is formed by the mutual sharing of electrons between the bonded atoms. It is also called the molecular bond. Such bonds usually exist between two or more non-metals.

(1) {\text{CaC}}{{\text{O}}_{\text{3}}}  

Its constituents are {\text{C}}{{\text{a}}^(2 + )} and {\text{CO}}_3^(2 - ) ions. The bond between calcium and carbonate ions is an ionic bond. But the bond between the carbon atom and the oxygen atom of carbonate is formed by sharing of electrons so it is a covalent bond. So {\text{CaC}}{{\text{O}}_{\text{3}}} has both ionic and covalent bonding and therefore this option is correct.

(2) {\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2}  

It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So {\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2} has only covalent bonds and therefore this option is incorrect.

(3) {\text{C}}{{\text{H}}_3}{\text{OH}}  

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So {\text{C}}{{\text{H}}_3}{\text{OH}} has only covalent bonds and therefore this option is incorrect.

(4) {{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}  

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So {{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}} has only covalent bonds and therefore this option is incorrect.

Keywords: chemical bond, ionic bond, covalent bond, CaCO3, CH2Cl2, C2H12O6, CH3OH, carbon, hydrogen, oxygen.

CaCO3 is the substance that contains both ionic and covalent bonds. Calcium ions (Ca2+) and carbonate ions (CO3-2) make up the salt known as CaCO3. Ionic bonds, which are created when one atom donates electrons to another atom, are what bind the calcium and carbonate ions together.

Three oxygen atoms and one carbon atom, linked together by covalent bonds, make up the carbonate ion. The three oxygen atoms and the carbon atom share electrons to create a covalent connection. Atoms exchange electrons to make covalent connections, whereas atoms give away electrons to produce ionic bonds.

In CaCO3, an ionic connection is created when the calcium atom donates electrons to the carbonate ion. The carbon atom shares electrons at the same moment.
