What is dynamic equilibrium? What is dynamic equilibrium? Dynamic equilibrium in a chemical reaction is the condition in which t

he rate of the forward reaction is lower than the rate of the reverse reaction. Dynamic equilibrium in a chemical reaction is the condition in which the rate of the forward reaction is higher than the rate of the reverse reaction. Dynamic equilibrium in a chemical reaction is the condition in which the rate of the forward reaction equals the rate of the reverse reaction.

Answer:

The correct answer is: Dynamic equilibrium in a chemical reaction is the condition in which the rate of the forward reaction equals the rate of the reverse reaction.

Explanation:

Dynamic equilibrium is a chemical equilibrium between froward reaction and backward or reverse reaction where rate of reaction going forwards is equal to the rate of reaction going backward (reverse).  

Some other properties of dynamic equilibrium are:

  • Chemical equilibrium are attained is closed system.
  • The macroscopic remains constant like: volume, pressure, energy etc.
  • The concentration of the reactants and products remain constant.They are not always equal.

lubasha [3.4K]

Answer:

Option A

Explanation:

The total heat absorbed during the chemical reaction is the total heat released by the surrounding.

Net change of heat is equal to zero

Hence, the energy liberated from the air or the walls of the containers would be equal to the energy absorbed by the chemical reactions is equal to 100 Kj

Thus, option A is correct

Nataly [62]

The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).

<h3>What is Empirical Formula ?</h3>

Empirical formula is the simplest whole number ratio of atoms present in given compound.

Element   %   Atomic mass   Relative no. of atoms  Simplest whole ratio

C            83.87       12                     \frac{83.87}{12} = 6.98                   \frac{6.98}{0.25} = 3

H            11.99         1                       \frac{11.99}{1} = 11.09                  \frac{11.09}{0.25} = 4

O            4.14          16                      \frac{4.14}{16} = 0.25                    \frac{0.25}{0.25} = 1

Thus the empirical formula is C₃H₄O₁.

<h3>How to find the Molecular formula of compound ?</h3>

Molecular formula = Empirical formula × n

n = \frac{\text{Molecular weight}}{\text{Empirical formula weight}}

  = \frac{386.64}{56}

  = 7

Molecular formula = Empirical formula × n

                               = 7 (C₃H₄O₁)

Thus from the above conclusion we can say that The main constituent of gallstones is cholesterol. Cholesterol may have a role in heart attacks and blood clot formation. Its elemental percentage composition is 83.87% C, 11.99% H, and 4.14% O. It has a molecular weight of 386.64 amu. Empirical formula is C₃H₄O₁ and Molecular formula is 7(C₃H₄O₁).

During the recharge of the lead storage battery, the chemical reaction that occurs is A.)nonspontaneous.
Paha777 [63]
The chemical reaction that occurs is spontaneous. By the time the battery will recharge the cycle lead sulfate (sulfation) starts to reconvert into sulfuric acid and also with lead. Also, during the reviving procedure as power courses through the water part of the electrolyte and water, (H2O) is changed over into its unique components, hydrogen, and oxygen.

Nesterboy [21]

Answer:

1.7\cdot 10^{15} g

Explanation:

Glucose reacts with oxygen do produce carbon dioxide and water:

C_6H_12O_6 (s) + 6 O_2 (g)\rightarrow 6 CO_2 (g) + 6 H_2O (l)

Given a daily mass of glucose:

m_1 = 5.0\cdot 10^2 g

Find moles of glucose:

n_1 = {5.0\cdot 10^2 g}{180.156 g/mol} = 2.775 mol

From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:

n_2 = 2.775 mol\cdot 6=16.65 mol

Convert this into mass using the molar mass of carbon dioxide:

m_2 = 16.65 mol\cdot 44.01 g/mol = 732.8 g

This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:

732.8 \frac{g}{person\cdot day}\cdot 365 days\cdot 6.5\cdot 10^9 people = 1.7\cdot 10^{15} g
