To determine the amount of a certain element in a compound, we use the ratio of the elements from the compound. We calculate is follows:
45.0 g CCl4 ( 1 mol CCl4 / 153.82 g CCl4 ) ( 1 mol C / 1 mol CCl4 ) ( 12.01 g C / 1 mol C ) = 3.5135 g carbon present
Hope this answers the question. Have a nice day.
Hey there!
For SN1 mechanism; the activation barrier is the C-I bond energy which is broken in the first step of the reaction.
The activation barrier is : 56 kcal/ mol = 5.6 kcal/ mole ( nearest 0.1)
Answer:The purple color is due to a mixture of the pink aqua complex and blue chloro complex and is not due to a new species.
Explanation:
The pink aqua complex of cobalt can be in equilibrium with blue chloro complex of cobalt giving rise to a purple colour. This equilibrium is governed by Le Chaterliers principle. A change in chloride or water concentration could shift the equilibrium towards any of the species causing its colour to become the dominant colour of the solution.
Answer:
I'd say it's a mixture, because you are putting different ingredients together to make something new; aka this salad.
We are going to use this formula :
Q = M*C*ΔT
when Q is the heat released by the material in J
and M is the mass in gram = 1600 g
C is the specific heat capacity of iron = 0.4494 J/g
and ΔT is the changing in temperature = 155 - 25 = 130 °C
So by substitution:
∴ Q = 1600 g * 0.4494 J/g * 130 °C
= 93475 J
∴ The amount of heat released in Joule = 93475 J
