Ihave some questions about the lab report on spectrophotometric analysis of the percentage of cranberry juice in cranberry apple juice
1)using the entire set of percentages of purrs cranberry juice in cranberry apple juice ,what is the overall averages, standard deviation and ranges of percentages of pure cranberry juice?
given concentration(%) and absorbance(a)
5%=0.04
10%=0.22
15%=0.40
20%=0.55
25%=0.68
30%=0.90
2)if apple juice has a non zero absorbance at the lamda max, how would this affect your calculations in calculating the percent cranberry in cranberry apple? would you calculations report a percent cranberry that is too high or too low?

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.  

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

i think   the answer is c hope i'm right
