Propane is C3H8
So Molar mass propane = 3*12 + 8*1 = 44 <span>
No. of moles of propane = 167/44 = 3.795 moles</span>
From the stoichiometry: <span>
No. of moles of hydrogen = 3.795 moles * (8 moles
hydrogen / 1 mole propane) = 30.36 moles
Using Avogadros number, 1 mole of any substance
contains 6.022 x 10^23 atoms, therefore:
<span>No. of hydrogen atoms = 30.36 * 6.022 x 10^23 =
1.828 x 10^25 atoms</span></span>
2 or more simple machines I hope this help :)
Answer: This is simple, if it has a high flammability, and you light it on fire, then that would be a chemical change.

Answer:
A. Passive Transport is migration of a molecule from one side of the cell membrane to the other, from an area of high electrochemical potential to a region of lower electrochemical potential.
B. Diffusion is an individual molecule of a material moving from a high-concentration location to a low-concentration area over a semipermeable barrier
C. Osmosis is the movement of molecules of water through a cell's partly permeable membrane from a liquid with a large concentration of water molecules to a solution with a lower concentration of water molecules.
D. Facilitated Diffusion are molecules that diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
E. Active transport is the transport of molecules across a cell membrane against a concentration gradient from a low-concentration region to a high-concentration region.
F. Selectively permeable is when some chemicals or ions pass across the membrane, while others are blocked.
G. Cellular respiration are organisms mix oxygen with food molecules, directing the chemical energy in these substances into life-sustaining processes while eliminating carbon dioxide and water as waste material.
