Explanation:
A mixture is defined as a substance in which two or more components are mixed together. Components in a mixture do not chemically combine together.
For example, sugar in water.
When solute particles completely and evenly mixed in a solvent then it is known as a homogeneous mixture. A homogeneous mixture is also known as a solution. For example, salt in water.
When solute particles are not evenly mixed in a solvent then it is known as a heterogeneous solution. For example, sand in water.
A compound is a substance in which two or more atoms are chemically combined together in a fixed ratio by mass. For example, is a compound.
Thus, we can conclude that given terms with their definitions are matched as follows.
1. Matter that is physically combined; has two forms of itself (homogeneous and heterogeneous) - Mixture.
2. A substance that that has uniform composition of two or more substances that cannot be seen - homogeneous mixture.
3. A substance that that has non-uniform composition of two or more substances that can be seen - heterogeneous mixture.
4. Substance composed of two or more elements bonded in a certain ratio by mass - Compound.
5. An example of a homogeneous mixture in a liquid form - solution.
Answer:
−2399.33 kJ
Explanation:
If NH₄NO₃ reacts with fuel oil to give a ΔH of -7198 for every 3 moles of NH₄NO₃
What is the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction
∴ For every 1 mole, we will have of the total enthaply of the 3 moles
so, to determine the 1 mole; we have:
= −2399.33 kJ
∴ the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction = −2399.33 kJ
