Which form of bonding holds cesium chloride (CsCl) together?a. hydrogen bonding
b. covalent bonding
c. metallic bonding
d. ionic bonding

Answers

Answer 1
Answer: The correct answer is D. Cesium chloride is held together by ionic bonding. This substance is a salt like sodium chloride. It is also soluble in water. When it dissociates, it forms into cesium ions and chloride ions.

What is an ionic bond

Answers

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Answer:

Ionic bond is formed by the cations and anions and their attractive forces.

Which equation represents a decomposition reaction?(1) CaCO3(s) ==>CaO(s) + CO2(g)
(2) Cu(s) + 2AgNO3(aq) ==>2Ag(s) + Cu(NO3)2(aq)
(3) 2H2(g) + O2(g) ==>2H2O(l)
(4) KOH(aq) + HCl(aq) ==>KCl(aq) + H2O(l)

Answers

Answer : The correct option is, (1)

Explanation :

The option (1) reaction is an example of decomposition reaction because in this reaction the larger compound, calcium carbonate decomposes into smaller molecule, calcium oxide and carbon dioxide.

Decomposition reaction : It is a type of reaction in which a larger compound decomposes into a smaller molecule or elements.

AB\rightarrow A+B

The option (2) reaction is an example of single displacement reaction because in this reaction the most reactive metal, copper displace the less reaction metal, silver.

The option (3) reaction is an example of combination reaction because in this reaction two reactants, hydrogen and oxygen react to give a single product as water.

The option (4) reaction is an example of double displacement reaction because in this reaction a positive cation and a negative anion of two reactants exchange their places to give two new products.

Hence, the correct option is, (1)
Answer (1 )

CaCO3(s) ==>CaO(s) + CO2(g)

The minimum energy required to start a reaction is: enthalpy (E1) enthalpy (E2) activation energy (A.E.) heat of reaction

Answers

The answer is activation energy. This is the minimum amount of energy needed to start a reaction. This is introduced by Svante Arrhenius. Also, it is the maximum amount of energy required. Activation energy can also be thought of the energy barrier.

The minimum energy required to start a reaction is called activation energy (A.E.).

(Option C)

What is activation energy?

Activation energy is the energy barrier that reactant molecules must overcome to transform into products during a chemical reaction.

It is the energy difference between the energy levels of the reactants and the transition state on the reaction's potential energy diagram.

Enthalpy (E1 and E2) and heat of reaction are related to the energy changes during the course of a reaction but are not directly related to the energy barrier required to initiate the reaction.

Enthalpy (H) refers to the total heat content of a system, while heat of reaction (ΔH) represents the energy difference between the products and reactants at constant pressure.

#SPJ6

Which statement describes the particles of an ideal gas based on the kinetic molecular theory?(1) The gas particles are relatively far apart and have negligible volume.
(2) The gas particles are in constant, nonlinear motion.
(3) The gas particles have attractive forces between them.
(4) The gas particles have collisions without transferring energy.

Answers

The particles are in a constant nonlinear motion.
A. They are far apart and have negligible volume. This makes it easier to calculate certain quantities such as temperature, pressure, and volume. If the gas particle volume is added, then the complex van der Waals equation has to be used to calculate these same quantities. We also assume that they are far apart because this implies that they will not collide.
