Answer: Mechanical energy depends on the motion or position of an object.
Explanation:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
Answer: Empirical formula is
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 60.87 g
Mas of H = 4.38 g
Mass of O = 34.75 g
Step 1 : convert given masses into moles.
Mass of C =
Moles of H =
Moles of O=
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For H =
For O =
The ratio of C:H:O= 2 : 2: 1
Hence the empirical formula is
