Answer:
D. 5 moles
Explanation:
C3H8 + 5O2 → 4H2O + 3CO2
5 mol 3 mol
So, to make 3 mol CO2 5 mol O2 are needed.
1. we used <u>Symbol</u> to represent an element.
2. The chemical formula of a molecule shows the <u>number and kind of atoms contained in the molecule</u>.
3. K (potassium) is the atom among the given choices.
4. CO (carbon - monoxide) is the molecule among given choices.
Due to gravity, layers of Sediment, originally form horizontally.
hope this helps!
Answer:
Option D
A reversible process is one in which a large change in conditions can reverse its direction.
Explanation:
A. Temperatures of a few nanokelvins can be achieved in a Bose-Einstein condensate. TRUE
b. A perfect crystal of any substance at 0 K has minimum entropy. is TRUE
c. The standard molar entropy of a substance at temperature T is a measure of the quantity of energy that must be dispersed in that substance for it to exist at T. is TRUE
d. A reversible process is one in which a large change in conditions can reverse its direction. is FALSE
e. Entropy is a measurement of the nanoscale dispersal of energy in a sample of matter. is TRUE
A reversible reaction is one that can return to it's normal direct even if an infinitesimal change is applied to some of it's conditions.
