Moles of ammonium sulfide = 5.80 mol
The formula of ammonium sulfide is (NH₄)₂S
So each molecule of ammonium sulfide has (4 x 2) or 8 atoms of H
One mole of ammonium sulfide has 8 moles of H
5.80 mol of ammonium sulfide has (8 x 5.8) or 46.4 moles of H
As per the definition of Avogadro's number, 1 mole = 6.022 x 10²³ atoms
46.4 moles of H x (6.022 x 10²³ atoms/ 1 mole of H)
= 2.8 x 10²⁵ H atoms
Therefore, 2.8 x 10²⁵ H atoms are in 5.80 mol of ammonium sulfide.
Answer:
7366.328 kPa.
Explanation:
- The critical pressure of carbon dioxide is 72.7 atm.
- To convert from atm to kPa, we use the relation that:
1.0 atm = 101.325 kPa.
- Applying conversion factor:
<em>The conversion factor = (101.325 kPa/1.0 atm)</em>
<em></em>
∴ The critical pressure of carbon dioxide (in kPa) = (72.7 atm)(101.325 kPa/1.0 atm) = 7366.328 kPa.
Answer:
D. Cytokinesis
Explanation:
Mitosis is the cell division that involves the synthesis of two genetically identical daughter cells. Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase. Following this four processes is another called CYTOKINESIS
Cytokinesis, which occurs after nuclear division, is the division of the cytoplasm. According to this question, the observation made when viewing the specimen was that "the cell has a narrow middle part which almost separates into two bulging ends and which looks like the number 8". This described the process of CYTOKINESIS in plant cell specifically.
Explanation:
1L=1000mL
1dm³=1L
1dm³=1000cm³
29.84ml-29.00ml=0.84ml
Density=mass(g)/volume(cm³)
=6.6g/(0.84cm³)
=?
