Answer:
1. Heterogeneous: Mixtures in which composition is not uniform throughout. For example, soil.
2. Homogeneous: Mixtures that have uniform composition throughout. For example, air.
3. Solute: the component of a solution which is present in smaller quantity. For example, Sugar in water
4. Solvent: the component of a solution which is pr3esent in larger quantity. For example, water
5. Solution: A solution is a homogeneous mixture of two or more substances. For example brass.
6. Mixture: When two or more compounds or elements mix up physically they from a mixture.
7. Colloid: Solutions in which particles are large and possess the characteristics of the Tyndall effect. For example milk.
8. Dissociation: the splitting of a molecule into smaller molecules is called dissociation.
9. Pure substance: A pure substance is a type of matter having definite properties.
10. Suspension: Suspensions are heterogeneous mixtures of undissolved particles. For example milk of magnesia.
11. Element: element is a substance made up of the same number of atoms.For example hydrogen
12. Compound: Compound is a substance made up of two or more elements. For example water.
The answer is C
Hope this help
Answer:
A gas with a rotten egg smell is evolved
Explanation:
When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;
Fe(s) + S(s) -----> FeS(s)
This is a direct combination reaction.
Subsequently, when dilute H2SO4 is added, the following reaction takes place;
FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)
He immediately observes the evolution of a gas with a rotten egg smell.
