Answer:
False
Explanation:
Every chemical element undergoes a reaction in order to fulfill the completion of their outermost shell. This is the case of nitrogen (symbol "N"), which is an element found in group 5 of the periodic table with atomic number 7 (i.e. 1s2 2s2 2p3). It possesses three valence electrons in it's outermost shell.
Looking at the configuration of the Nitrogen atom, it requires three electrons to complete its electron shell. Hence, nitrogen will enter a reaction in order to have its need for THREE ELECTRONS met in order to have its electron shell full.
Note that, nitrogen enters a chemical reaction to look for three electrons not three neutrons.
According to Avagadros law 1 mole of a substance contains 6.02 × 10^23 particles.
Thus, 1 mole of C6H14 contains 6.02 × 10^ 23 molecules,
Therefore, 9.25 × 10^24 molecules will have;
(9.25 × 10^24)/ (6.02 ×10^23)
= 15.365 moles.

Answer:
A. 97.8 mm
Explanation:
There are 10 divisions between 9 cm (90 mm) and the end of the ruler (10 cm or 100 mm).
Each division equals 1 mm.
Each 5 mm mark has a longer tick, and the dashed red line is between the 97 mm and 98 mm marks.
You would normally estimate to the nearest tenth of a division. An estimate of 0.8 mm is reasonable.
The length of the object is 97.0 mm + 0.8 mm = 97.8 mm.
B is wrong. You can't possibly estimate to the nearest hundredth of a division.
C is wrong. The dashed red line slightly before the 98 mm mark.
D is wrong. If the dashed red line were exactly on the 98 mm mark, you would record the measurement as 98.0 mm. This indicates that you measured the object to zero tenths on either side of the mark.
