Answer: All solids absorb heat as they melt to become liquids.
Explanation:
Answer:
2365.0 g
Explanation:
First we <u>convert 1.2 x 10²⁵ particles into moles</u>, using <em>Avogadro's number</em>:
- 1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol
Then we <u>convert 19.9 moles of NiCO₃ into grams</u>, using the <em>molar mass of NiCO₃</em>:
- NiCO₃ Molar Mass = 118.702 g/mol
- 19.9 mol * 118.702 g/mol = 2365.0 g
