<h2>The required "option is b) potential energy".</h2>
Explanation:
- The energy which is associated with the motion of the object is called kinetic energy.
- The energy which is associated with the amount of heat released is known as thermal energy.
- The energy which is released during a chemical reaction is known as chemical energy.
Therefore, option (a), (c), and (d) are incorrect.
- The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
- Hence, the correct option is potential energy.
Answer:
I think the answer is 6.022*10^23
Answer:
True.
Explanation:
To know which option is correct, let us calculate the number of mole present in 60g of calcium. This is illustrated below:
Mass of Ca = 60g
Molar Mass of Ca = 40g/mol
Number of mole Ca =....?
Number of mole = Mass/Molar Mass
Number of mole of Ca = 60/40
Number of mole Ca = 1.5 moles.
From the calculations made above, we can see that 1.5 moles are present in 60.0 grams of calcium
An empirical formula is the chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms.
For example the molecule 'CH2O' is the empirical formula for glucose.
