Answer:
C8H20P4F8
Explanation:
Molecular formula is based off a ratio of the molecular formula's molar mass divided by the empirical formula's molar mass.
The molar mass of the empirical formula C2H5PF2 is 98.02g. We find this by adding the molar masses of all elements in the formula, multiplied by their subscripts.
2(12.01) + 5(1.01) + 30.97 + 2(18.99) = 98.02
We then divide the molecular molar mass by the empirical molar mass.
392.16/98.02 = 4
This tells us that the molecular formula has 4 times the mass of the empirical formula. Because mass comes from the elements in the formula, we multiply all the subscripts by 4 to get the molecular formula.
2x4 = 8
5x4 = 20
1x4 = 4
2x4 = 8
So the molecular formula is C8H20P4F8
Answer: Out of 118 elements, 94 occur naturally
Answer:
The answer is C. 48 grams
Explanation: If the mass of all the ingredients is 48 grams the that would be your in total answer
the laws of thermodynamics
Explanation:
The movement of thermal energy is controlled by the laws of thermodynamics.
- The total energy of a system is the sum of all its potential and kinetic energy associated with it.
- Thermal energy is a form of kinetic energy that causes the motion of particles of medium.
- It is produced when there is temperature differences between two bodies.
- The movement of thermal energy is from a body with a high energy to a low one.
- When thermal equilibrium is reached between two bodies, thermal energy ceases to flow.
- Thermodynamics deals with heat changes.
