Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase <em><u>"I think, therefore I am"</u></em>.
Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to <em><u>Rene Descartes</u></em>. This Latin phrase is roughly translated as <em><u>"I think, therefore I am"</u></em>, which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

Answer:
Results from method B is more reliable than method A.
Explanation:
The two method that are used for the analysis produced different results. The first method that is method A gives higher value of the iodine content than the method B.
When 
was added to water, method A showed an increased in the iodine content and it increases with the increase in the amount of .
Where as in the method B, there is no change in the results. Therefore the measurements provided by the method A shows an inference of ion.
The measurement of the iodine content is affected by the presence of the ion in water.
Since in method B there is no change in measurement, it is independent of the presence ion in water.
As higher iodine content is given by method A, so ion must be present in original water that must be interfering the measurement. Hence, method B is more reliable.
Answer:
Mass = 112.54 g
Explanation:
Given data:
Mass of copper = 18 g
How much copper(II) nitrate formed = ?
Solution:
Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag
Number of moles of copper:
Number of moles = mass/ molar mass
Number of moles = 18 g/ 29 g/mol
Number of moles = 0.6 mol
Now we will compare the moles of Cu with Cu(NO₃)₂ .
Cu : Cu(NO₃)₂
1 : 1
0.6 : 0.6
Mass of Cu(NO₃)₂ :
Mass = number of moles × molar mass
Mass = 0.6 mol × 187.56 g/mol
Mass = 112.54 g
Answer:
8
Explanation:
From the question given above, the following data were obtained:
t–butyl ion = (CH₃)₃C⁺
Number of valence electron =?
The valence electron(s) talks about the combining power of an element or compound as the case may be.
Considering the t–butyl ion, (CH₃)₃C⁺ we can see that it has a charge of +1 indicating that it has given out 1 electron to attain the stable octet configuration which has a valence electrons of 8. Thus, the valence electron of t–butyl ion, (CH₃)₃C⁺ is 8
