Answer:
About 1.301 atm
Explanation:
The formula that you should is PV=nRT, where P stands for pressure, V stands for volume, n stands for the number of moles, R stands for the universal gas constant, and T stands for temperature in Kelvin. Since the volume, number of moles, and universal gas constant don't change, you don't need to worry about them.
1.07V=393nR
PV=498nR
P=1.301 atm. Hope this helps!
1. Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
2. Mitosis is important because it plays an important part in the development of embryos, and it is important for the growth and developemet of our body as well.
3. The four phases of mitosis are: Prophase, metaphase, anaphase, and telophase.
4. Two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated.
5. During S phase all of the chromosomes are replicated.
I hope that helps! c:
Answer:
0.087 moles of water
Explanation:
Given data:
Number of molecules of water = 5.24×10²² molecules
Number of moles of water = ?
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules of water
5.24×10²² molecules × 1 mol / 6.022 × 10²³ molecules
0.87×10⁻¹ mol
0.087 mol
Continental crust, oceanic crust, mantle , outer core , and inner core.
Answer:
Despite their similar use in wastewater treatment as flocculants and coagulants, FeCL2 and FeCl3 have different<u> molecular formula</u>,<u> colours</u>, and <u>common names
</u>
Explanation:
<u>FeCl3:
</u>
• Purple-red colour as anhydrous crystal and yellow in solution
• Used as catalyst
• In Iron (III) chloride the iron atoms have lost three electrons so you need three chlorine atoms, hence the chemical formula FeCl3.
• Common name: <em>Ferric chloride
</em>
<u>FeCl2:
</u>
• In Iron (II) chloride the iron atoms have lost two electrons so you need two chlorine atoms, hence the chemical formula FeCl2.
• Difference in formula means different molecular masses as well.
• White colour as anhydrous salt and green in solution
• Common name: <em>Ferrous Chloride
</em>
