NemiM [27]3 years ago
5 0
K=39g
Br=79.9
(39+79.9)=237.8g

C=12
H=1g
O=16g
6(12)+12(1)+6(16)=180g
237.8+180=417.8g total

Monica [59]

1) The names of the molecules

2) Write the chemical equation

OH^-+CH_3F\rightarrow CH_3OH+F^-

3) Balance the chemical equation

1 fluoride in the reactants and 1 fluoride in the products

1 carbon in the reactants and 1 carbon in the products

4 hydrogens in the reactants and four hydrogens in the products

1 oxygen in the reactants and 1 oxygen in the products

Since the number of atoms in the reactants is the same that the number of atoms in the products, the chemical equation is balanced.

An excited ozone molecule, O3*, in the atmosphere can undergo one of the following reactions,O3* → O3 (1) fluorescenceO3* → O +
Maurinko [17]

Answer:

The simplified expression for the fraction  is  \text {X} =    \dfrac{  {k_3  \times cM} }{k_1 +k_2 + k_3 }

Explanation:

From the given information:

O3* → O3                   (1)    fluorescence

O + O2                      (2)    decomposition

O3* + M → O3 + M    (3)     deactivation

The rate of fluorescence = rate of constant (k₁) × Concentration of reactant (cO)

The rate of decomposition is = k₂ × cO

The rate of deactivation = k₃ × cO × cM

where cM is the concentration of the inert molecule

The fraction (X) of ozone molecules undergoing deactivation in terms of the rate constants can be expressed by using the formula:

\text {X} =    \dfrac{ \text {rate of deactivation} }{ \text {(rate of fluorescence) +(rate of decomposition) + (rate of deactivation) }  } }

\text {X} =    \dfrac{  {k_3 \times cO \times cM} }{  {(k_1 \times cO) +(k_2 \times cO) + (k_3 \times cO \times cM) }  }

\text {X} =    \dfrac{  {k_3 \times cO \times cM} }{cO (k_1 +k_2 + k_3  \times cM) }

\text {X} =    \dfrac{  {k_3  \times cM} }{k_1 +k_2 + k_3  }    since  cM is the concentration of the inert molecule

Deffense [45]

Based on factors affecting solution formation;

  • Strong solvent-solute intermolecular forces favors solution formation.
  • Increase in entropy favours solution formation
  • Decrease in enthalpy favours solution formation

<h3>What is a solution?</h3>

A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.

Factors that affect solution formation include:

  • strength of intermolecular forces between solute and solvent
  • entropy
  • enthalpy

Strong solvent-solute intermolecular forces favors solution formation.

Increase in entropy favours solution formation

Decrease in enthalpy favours solution formation.
