Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
Answer: Vitamins
Explanation:
they are nutrients that are made by living things
Atoms are (stable) if it has (valence) electrons in its outer most energy level.
This problem is providing the mass, energy, initial temperature and specific heat of a sample of copper that is required to calculate the final temperature.
Thus, we recall the general heat equation:

Which has to be solved for the final temperature,
as follows:

Finally, we plug in the numbers to obtain:

However, this result is not given in the choices.
