Sharing of electrons always means its a covalent bond, and unequal means it is polar, so it is a polar covalent bond
Answer:
0.32 mole
Explanation:
From the question given above, the following data were obtained:
Initial mole (n₁) = 0.31 mole
Initial pressure (P₁) = 742 torr
Final pressure (P₂) = 759 torr
Final mole (n₂) =?
The final mole of the gas in the drum can be obtained as follow:
P₁/n₁ = P₂/n₂
742 / 0.31 = 759 / n₂
Cross multiply
742 × n₂ = 0.31 × 759
742 × n₂ = 235.29
Divide both side by 742
n₂ = 235.29 / 742
n₂ = 0.32 mole
Thus, the final mole of the gas in the drum is 0.32 mole
Data:
Explanation:
The rate constant as a function of the temperature can be expressed using the Arrhenius equation, as follows,
Then, find a value for the constant A, according to the data given in the exercise,
As the rate constant has units then, the reaction corresponds to one of first order. Then, the reaction corresponds to:
Which tell the amount of mass (mol) is produced by second per unity of volume.
Answer:
If the reaction goes twice fast, the reaction rate corresponds to,
The expression above can be reduced to:
Replacing k(T) in order to obtain the temperature T,
Replacing all values,
I’m not really sure but I wanna think I te catiónic
<u>Answer:</u> The expression of equilibrium constant is
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
Concentration of pure solids and pure liquids are taken as 1 in the expression.
For the given chemical reaction:
The expression of for above equation follows:
Hence, the expression of equilibrium constant is
