Answer is: there is 1,368·10²⁵ atoms of carbon.
N(C₃H₈) = 4,56·10²⁴.
From molecular formula: in one molecule of propane there is three atoms of carbon:
N(C) = 3 · 4,56·10²⁴.
N(C) = 1,368·10²⁵.
It should be rounded to 1 so I'm guessing true
If I'm understanding the question correctly the answer would the proton to neutron ratio.
Answer:
The correct statements are (II) and (III).
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
This is a type of exothermic reaction because heat is released in the reaction.
On increasing the temperature
If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an exothermic reaction, forward reaction will increase the temperature. Hence, the equilibrium will shift in the left direction.
And by moving to left side amount of ammonia will decrease accompanied by the change in the value of an equilibrium constant.
The correct answer is:
2 atoms and 2 lone pairs; 2 atoms and 1 lone pair.
Both AX₂E₂ and AX₂E have different electron domain geometry; AX₂E₂ is tetrahedral and AX₂E is trigonal planar but both of them has the same molecular geometry
