Answer: Hello i am confused are you asking a question?
Explanation:
The percentage composition of CF4 is %C = 13.64% and %F = 86.36%
The solution are as follows:
Molar mass of CF4 = 88
<span>molar mass of C = 12 </span>
<span>molar mass of F = 4x19 = 76 </span>
<span>% C = 12/88 x 100 = 13.64% </span>
<span>% F = 76/88 x 100 = 86.36%</span>
Hi!
Your Question,
what career is when a person anlysis food in laboratory ?
Answer,
Food makes the analysis that I know is trying to engineer food. That's called that in Turkey
Good Luck

The largest risks while designing a model to withstand a village include that the model does not mitigate the effects of the tsunami or only mitigates the effects partially, which would cause damages to the homes.
Designing a model to withstand the effect of any natural phenomenon such as an earthquake, fire or tsunami is not an easy task and will require the following cycle:
- Designing the model.
- Testing the model.
- Making changes or designing a new model.
In the case of a model for tsunamis, it is likely the following problems occur:
- The model does not protect the houses from tsunamis.
- The model does not protect the houses completely.
This would lead to negative effects such as:
- Damages in the houses.
- Dead or injured people.
- Destruction of infrastrcture.
Note: This question is incomplete because the context is missing; here is the missing part.
Protecting Your Model Village from Tsunamis this task, you will design a model village to withstand the effects of a tsunami.

Answer : The mass of 
needed are, 48 grams.
Explanation :
First we have to calculate the moles of 
Now we have to calculate the moles of
The given balanced chemical reaction is:
From the reaction, we conclude that
As, 2 mole of produces from 1 mole of
So, 3 mole of produces from 
mole of
Now we have to calculate the mass of
Molar mass of = 32 g/mole
Therefore, the mass of needed are, 48 grams.
