Answer:
Energy transfers from the metal to the water and calorimeter until they are all at room temperature.
Explanation:
Calorimetry is the process that is used to determine the amount of heat that has been transferred in any process. In any chemical or physical process, the amount of energy is required. This energy is measured by the process of calorimetry. A calorimeter is a device that is used in this process. The heat that has been used in the process is measured and the change in the temperature is noted.

Answer:
2.03 × 10⁻⁴ moles
Explanation:
To convert atoms to moles, use Avogadro's number (6.022 × 10²³).
(1.22 × 10²⁰ atoms)/(6.022 × 10²³ atoms/mol) = 2.03 × 10⁻⁴ mol
Answer:
the answer would be "B"
Explanation:
Elements with the same number of valence electrons are found in the same column of the Periodic Table. All elements in the first column of the Periodic Table have 1 valence electron in an s orbital. These elements are known as Group 1A metals or alkali metals.
