Answer:
Explanation:
iron is element number 26 this means that it has 26 number of electron and proton in its atomic structure so its atomic number is 26
Answer:
Empirical formula is NH₃
Explanation:
Given data:
Percentage of hydrogen = 82%
Percentage of nitrogen = 18%
Empirical formula = ?
Solution:
Number of gram atoms of H = 18 / 1.01 = 17.8
Number of gram atoms of N = 82 / 14 = 5
.9
Atomic ratio:
H : N
17.8/5.9 : 5.9/5.9
3 : 1
H : N = 3:1
Empirical formula is NH₃
Answer:
After leaving the small intestines, the undigested food enters the colon ( large intestines)
Explanation:
When the chyme is exhausted of its nutrients, the remaining waste material changes into the semi solids called as feces. These pass into the large intestine, where gut flora further break residual proteins and starches.
Water is absorbed here and the remaining waste matter is stored prior to defecation.
The passage of the digesting food in the colon is a lot slower, taking about 12 to 50 hours until it is removed by defecation. The colon mainly serves as a site for the fermentation of digestible matter by the gut flora.
Colon is the largest part of the GI tract.
It would be S - 35 because people made the short form of each element to make it easier to understand and it is also used all around the world and 35 is the atomic number. Hope this helps ;)
