8 0

\color{Black}\huge{Answer}

  • It has a very high melting point as the ionic bond is very strong between them.
  • More force is required to break down.
  • Silicon dioxide is a giant covalent structure.
  • It also has the highest melting point because the covalent bonds between them is the strongest.

1. How much energy must be absorbed to break the bonds of the 2 molecules of HCl?
IRISSAK [1]

Bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.

<h3>What is Bond energy?</h3>

The term bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.

The energy that must be supplied to break the bonds in two molecules of HCl is 862 J. The energy released is obtained from; 862J - [436 +262] = 164J.

The total energy of the reaction is 164J, this is called the enthalpy change. Based on this value of the total energy, the reaction is endothermic. Hence, it is true that; "It takes more energy to break the two H–Cl bonds than is released when forming the H–H and Cl–Cl bonds."

In a reaction, 25 grams of reactant
Vsevolod [243]

Answer:

D. 15g

Explanation:

The law of conservation of mass states that, in a chemical reaction, mass can neither be created nor destroyed. This means that the amount of matter in the elements of the reactants must be equal to the amount in the resulting products.

In this question, 25 grams of a reactant AB, was broken down in a reaction to produce 10 grams of products A and X grams of product B. According to the law of conservation of mass, the mass of the reactant must be equal to the total mass of the products. This means that 25 grams must also be the total mass of both products in this reaction. Hence, if product A is 10 grams, product B will be 25 grams - 10 grams = 15 grams.

Therefore, product B must be 15 grams in order to form a total of 25 grams when added to the mass of product A. This will equate the mass of the reactant AB and fulfill the law of conservation of mass.
