Answer:
Energy and how it can change forms. Kinetic, potential, and chemical energy.
Answer:
The correct answer to the following question will be Option B (temperature of the water).
Explanation:
- The solubility of that same salt which appears whenever the substance is added in some kind of a fluid which already incorporates another origin of many of its atoms.
- The solubility of such a substance throughout a given quantity of water is predominantly dependent on the whole of the water temperature.
<h3><u>Answer;</u></h3>
D. Process B, because it is a spontaneous process.
<h3><u>Explanation</u>;</h3>
- A spontaneous process is one that will occur without any energy input from the surroundings.
- A spontaneous reaction may involve an increase or decrease in enthalpy, it may involve an increase or decrease in entropy, but it will always involve a decrease in free energy that is a negative ΔG.
- Therefore; process B is spontaneous since it has a negative ΔG
Answer:
233 g
Explanation:
Let's consider the following reaction.
CaCO₃ → CaO + CO₂
We can establish the following relations:
- The molar mass of calcium carbonate is 100.09 g/mol.
- The molar ratio of calcium carbonate to carbon dioxide is 1:1.
- The molar mass of carbon dioxide is 44.01 g/mol
The mass of carbon dioxide produced from 530 g of calcium carbonate is:
