Answer:
D. 5 moles
Explanation:
C3H8 + 5O2 → 4H2O + 3CO2
5 mol 3 mol
So, to make 3 mol CO2 5 mol O2 are needed.
The answer is: A
C-14 is not stable and this is the reason why it goes through radioactive decay.
A: Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
The hybridization of the central carbon compound CH4 tetrahedral is
SP^3 hybridization
In tetrahedral molecular geometry a central atom is located at the center with 4 substituent that are located at the corners of tetrahedron. Example in methane molecules is made up of b equally spaced sp^3 hybrid orbital forming bond angle of 109.5
