Answer:
0. 000115
Explanation:
A percentage is defined as a ratio with a basis of 100 as total substance. Convert a percentage to decimal implies to divide the percentage in 100 because decimal form has as basis 1.
For the isotopic forms:
1H: 99.98% → As percent.
99.98% / 100 = 0.9998 → As decimal form.
2H: 0.0115% → As percent.
0.0115% / 100 = <em>0. 000115</em>→ As decimal form.
<u>Ans: O2 because it produces only 0.20 mol of NO</u>
<u>Given:</u>
Mass of NH3 = 4.0 g
Mass of O2 = 8.0 g
<u>To determine:</u>
The limiting reagent in the given reaction
4NH3 + 5O2 → 4NO + 6H2O
<u>Explanation:</u>
# moles of NH3 = 4.0/17 g.mol-1 = 0.2353 moles
# moles of O2 = 8.0/32 = 0.25 moles
Based on the reaction stoichiometry:
1 mole of NH3 produces 1 mole of NO
Therefore, 0.2353 moles of NH3 will produce: 0.2353 moles of NO
Similarly, 1 mole of O2 will produce 4/5 moles of NO
0.25 moles of O2 will form: 0.25*4/5 = 0.2 moles of NO
Thus, O2 is the limiting reactant.
When there are 14c-lable uracil that are added to the growth medium of cells, the macromolecules that will be labled are RNA. Uracil is a nucleobase that make up the DNA or the RNA. In RNA, uracil binds with other nucleobase (adenine) through hydrogen bonds.
