Answer:
protons: positively charged, located in the nucleus
electrons: negatively charged, located outside the nucleus
neutrons: no charge, located in the nucleus
Answer:
Partial molar volumes help to assess the influence of pressure on phase equilibria or reaction equilibria. The prediction of partial molar volumes or excess volumes is a sharp test for theories of the fluid state.
On the other hand, the interpretation of partial molar volumes or excess volumes is usually difficult, if not impossible. Many mixtures exhibit positive and negative excess volumes, depending on composition, temperature, and pressure. Speculations why some mixture exhibits positive or negative excess volumina are futile, particularly if they are based on measurements at ambient pressure and temperature only.

Answer:
0.906 moles of calcium carbonate needed to produced 0.906 moles of carbon dioxide.
Explanation:
Given data:
Moles of carbon dioxide produced = 0.906 mol
Moles of calcium carbonate needed = ?
Solution:
Chemical equation:
CaCO₃ → CaO + CO₂
Now will compare the moles of carbon dioxide with calcium carbonate:
CO₂ : CaCO₃
1 : 1
0.906 : 0.906
So 0.906 moles of calcium carbonate needed to produced 0.906 moles of carbon dioxide.
