On the left (reactant) side you have 6 N-H bonds and 1 Cl-Cl bond 
<span>On the right (product) side you have 4 N-H bonds, 1 N-N bond and 2 H-Cl bonds </span>

<span>Add up the bond energies for each side (multiplying by the number of bonds) and calculate the difference for your ΔHº</span>

What is the mole ratio of D to A in the generic chemical reaction? 4A + B --&gt; C + D​
storchak [24]
<h3>Answer:</h3>

Mole ratio of D to A is 1 : 4

<h3>Explanation:</h3>

We are given the generic chemical equation;

4A + B → C + D​

We are supposed to determine the mole ratio of D to A

What is mole ratio?

  • Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
  • We determine the mole ratio using the coefficients of reactants or products in question.

For example;

  • In the equation, 4A + B → C + D​, the coefficient of A is 4 while the coefficient of D is 1.
  • This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
  • Thus, mole ratio of D to A  is 1 : 4

This experiment is more about understanding the colligative properties of a solution rather than the determination of the molar
Afina-wow [57]
Colligative properties are properties of solutions that result from adding solute to a solvent and that depend on the concentration of solute particles, but independent of the identity of the solute molecules or ions. The four colligative properties are boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure lowering.

The atomic mass of N is 14.01 g/mol, and the atomic mass of H is 1.008 g/mol. What is the molecular mass of NH3?
MakcuM [25]

Answer:

Option A = 17.03 g/mol

Explanation:

Given data:

Atomic mass of nitrogen = 14.01 g/mol

Atomic mass of hydrogen = 1.008 g/mol

Molecular mass of NH₃ = ?

Solution:

Molecular mass of NH₃ = (14.01 g/mol × 1) + (1.008 g/mol × 3)

Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol

Molecular mass of NH₃ =  17.03 g/mol

Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.

Convert 100mL to L. Show your work to receive full credit.
Ilya [14]

Answer:

100 ml = 0.1 L

I divided 100 by 1000 because 1000ml = 1L
