The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction.
<h3>What is an Exothermic reaction?</h3>
An Exothermic reaction in thermodynamics is a type of reaction that released energy from the system of reaction to it's surroundings which can be inform of light, heat or even electricity or sound.
Exothermic reaction has net negative standard enthalpy change.
Therefore, The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction

Answer:
A solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Explanation:
Answer:
55.4g
Explanation:
Given parameters:
Number of atoms in the bottle = 8.34 x 10²²atoms
Unknown:
Mass of air in the bottle = ?
Solution:
The given specie is argon.
Molecular mass of Argon = 40g/mol
To find the mass of this Argon ;
Mass = number of moles x molecular mass;
Let us find the number of moles of the Argon;
6.02 x 10²³ atoms can be found in 1 mole of any substance
8.34 x 10²² atoms will give mole of Argon
= 0.139mole of Argon
So;
Mass of argon = 40g/mol x 0.139mole = 55.4g
