Around 24.85 miles per hour
, divide the length value by 1.60
Given :
Concentration of product [A] = 0.371 M .
Rate constant , .
To Find :
The rate for the reaction .
Solution :
We know , for second order reaction , rate is given by :
Therefore , the rate for the second order reaction is 0.1 M/t .
Hence , this is the required solution .
Answer:
Cl2 + 2Br -> Br2 + 2Cl
Explanation:
There are 2 electrons in each side, so you can substract them and then up with 0 electrons
Answer:
The concentration of an anthracene solution is
Explanation:
From the question we are told that
The incident beam is
The fluorescence intensity is
The length of the medium is b = 0.875 cm
The molar extinction coefficient is
The proportionality constant k = 0.30
According to Lambert law the Absorbance of the anthracene solution is mathematically represented as
Where
and A is the Absorbance
Substituting value
Generally beers law can be represented mathematically as
where c is the concentration of an anthracene solution
Making c the subject of the formula
Substituting 0.875 cm for length = b ,
We have
Ans: 15.1 grams
Given reaction:
Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3
Mass of Na2CO3 = 20.0 g
Molar mass of Na2CO3 = 105.985 g/mol
# moles of Na2CO3 = 20/105.985 = 0.1887 moles
Based on the reaction stoichiometry: 1 mole of Na2CO3 produces 2 moles of NaOH
# moles of NaOH produced = 0.1887*2 = 0.3774 moles
Molar mass of NaOH = 22.989 + 15.999 + 1.008 = 39.996 g/mol
Mass of NaOH produced = 0.3774*39.996 = 15.09 grams
