Answer: Kinetic energy is energy possessed by an object in motion. ... Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v².
Answer:
True
Explanation:
All the chemical elements have their abbreviations as one or two letters
The first letter in the abbreviation is a capital letter and the second letter is always a small letter
Majority of abbreviations are based on their english names
The molar mass of calcium carbonate is 100 mg/mmol, so the
number of moles is:
moles CaCO3 = 500 mg / (100 mg/mmol) = 5 mmol
We see that there is 1 mole of Ca per 1 mole of CaCO3,
therefore:
<span>mass Ca = 5 mmol * (40.08 mg/mmol) = 200.22 mg</span>
I think your answer would be an Atom because it is referred to as the smallest unit of matter that retains the chemical properties of an element.
I Hope my answer help you :)
