Answer:
hyaluronic phosphoric acid
Answer:
Explanation:
The reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We see, that the equation is ballanced.
As we have data from only one reactant, we assume the other is in excess.
Ratio is 1:4 (stoichiometry). We solve this, by a rule of three:
1 mol of propane can produce 4 moles of water
Then, 4 moles of propane, may produce
( 4 . 4 ) /1 = 16 moles of water can be made.
Remember, we always have to work with the limiting reactant.
Answer:
helium, argon, krypton, xenon, and radon.
Explanation:
A unit cell is a simplest repeating unit in a crystal in which particle are freely vibrating
Sodium chloride having face centered cubic lattice in which sodium and chloride ion are arranged and vibrating.
The sodium ion are arranged on eight corners of the cube whereas they are also present on all the six centres of all six faces.
Thus, number of Na+ ion
Hence total of 14 sodium ions are present in NaCl lattice.
