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.

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.

Answer:
The Atmosphere Is a separate layer And Also could be classified as the Closest layer
Explanation:
Answer: the mass of an electron is approximately 9.10938356 × 10^-31 kilograms (kg)
Explanation:
The answer is: The name of the positively charged nonmetal ion is changed to end in –ide.
For example, a chemical compound containing sodium and chlorine is binary ionic compound sodium chloride (NaCl).
In this compound, sodium (Na) has positive charge and chlorine (Cl) has negative charge.
Chlorine is nonmetal and sodium is metal.
Metals have positive charge and nonmetals negative.
Explanation:
Let's analyze the statements one by one:
a) This process is exothermic.
True. The negative enthalpy change (-2,021 kJ) indicates that heat is released during the reaction, making it exothermic.
b) The enthalpy change for 2C₃H₇OH(l)+9O₂(g)→6CO₂(g)+8H₂O(l) is 2,021 kJ.
False. The balanced chemical equation and enthalpy change given are for the combustion of 1 mole of propanol, not 2 moles.
c) The enthalpy change for 2C₃H₇OH(l)+9O₂(g)→6CO₂(g)+8H₂O(l) is -4,042 kJ.
False. This statement suggests a doubled enthalpy change value in the wrong direction. The correct direction is negative (exothermic), but the magnitude is not doubled.
d) The enthalpy change for 2C₃H₇OH(l)+9O₂(g)→6CO₂(g)+8H₂O(l) is -2,021 kJ.
False. This statement suggests the correct direction but doubles the magnitude. The correct magnitude is -2,021 kJ for 1 mole of propanol.
e) This chemical process transfers heat from the surroundings to the system.
False. The process is exothermic, which means it releases heat from the system to the surroundings.
f) The enthalpy change for 2C₃H₇OH(l)+9O₂(g)→6CO₂(g)+8H₂O(l) is 4,042 kJ.
False. This statement suggests the correct magnitude but in the wrong direction. The correct direction is negative (exothermic).
g) This process is endothermic.
False. The process is exothermic, as indicated by the negative enthalpy change.
h) This chemical process transfers heat from the system to the surroundings.
True. An exothermic process like this releases heat from the system to the surroundings.
So, the correct statements are:
a) This process is exothermic.
e) This chemical process transfers heat from the surroundings to the system.
h) This chemical process transfers heat from the system to the surroundings.
