)scientists measure the amount of light passing through a sample in terms of percent transmittance (%t). percent transmittance is the fraction of original light that passes through a sample. recall that p0 is the amount of light entering the sample and p is the amount of light reaching the detector. using a spectrometer, a sample was analyzed to have a percent transmittance of 85%. what percentage of light was actually absorbed by the sample? (1 points)

%t= p/p0 * 100

Approximately 15%.

Explanation:

When light falls on an object, three major things; transmission, reflection and absorption occur. Transmission is the process by which light propagates or passes through an object. Reflection is the process in which light got reflected on hitting the surface of an object and absorption is the process in  which light rays are absorbed by an object.

From the given question, percent transmittance is the fraction of original light that passes through a sample.

                               %T = × 100

Since the sample has a percent transmittance of 85% after analysis, then the percentage of light absorbed by the sample is approximately 15%. This is because some percentage would have been reflected also.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

your answer would be a. 12.5 kg
