Answer:
record the data in writing
Explanation:
FALSE
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.

Explanation:
because they will bond together.
(2) CH2Cl2 (4) C6H12O6
The compound that has both ionic and covalent bonding is .
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)
Its constituents are and 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 has both ionic and covalent bonding and therefore this option is correct.
(2)
It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.
(3)
It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.
(4)
It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.

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.
