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:
Explanation:
In a simple cubic lattice lattice, the atoms are present at the eight corners of the cibe.
Since it is mentioned that the fluorine is present at the corners and also 1 corners are shared by 8 unit cells. So, share of atom in one unit cell is:-
Also, the metal, M occupy half of the body centre. A cube has only one body centre. So, share of M in each unit cell:-
Thus, the formula is:-
Or simplifying
Answer:
The correct answer is 0.50 mol (NH₄)₃PO₄
Explanation:
The balanced chemical equation between liquid ammonia (NH₃) and H₃PO₄ is the following:
3 NH₃ + H₃PO₄ → (NH₄)₃PO₄
According to the equation, 3 mol of ammonia produce 1 mol of ammonium phosphate. Thus, the stoichiometric ratio is 1 mol (NH₄)₃PO₄/3 NH₃. To calculate the moles of (NH₄)₃PO₄, we multiply the ratio by 1.50 mol NH₃:
1.50 mol NH₃ x 1 mol (NH₄)₃PO₄/3 NH₃ = 0.50 mol (NH₄)₃PO₄
