By combining two or more substances, a mixture is produced. A homogeneous solution tends to be identical, no matter how you sample it. Homogeneous mixtures are sources of water, saline solution, some alloys, and bitumen. Sand, oil and water, and chicken noodle soup are examples of heterogeneous mixtures. Q4.
Homogeneous Solutions. Heterogeneous Solutions. 1. They have consistent compositions. They are not uniform in composition: 2. Physically, the components of homogenous mixes are not separate. Physically dissimilar components make up a heterogeneous combination. 3. There are no discernible boundaries between the elements.
Q. Can anyone tell the difference between. Homogeneous and heterogeneous mixtures ? Q. (i) Write any three points of difference between homogeneous and heterogeneous mixture. (ii) Give two reasons for supporting the water is a compound not a mixture.
Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous. For example, assume the gene of hair colour has two alleles, one of the allele codes for brown (R) and the other codes for black (r). Homozygous will have the same colour alleles on ...
Heterogeneous mixture. (I) Homogeneous mixtures have uniform composition throughout the mixture. (II) The whole mixture is in same phase. (III) Components are not visible to the naked eye. (IV) Components cannot be separated easily. Eg.: Sugar + Water → Sugar solution. (I) Heterogeneous mixture have composition which may vary from point to point.
Heterogeneous catalysis. 1. In this process, the catalyst and reactants are present in the same phase. 1. In this process, the catalyst and reactants are present in a different phases. 2. They have high activity. 2.
Homogeneous solutions are solutions with uniform composition and properties throughout the solution. For example a cup of coffee, perfume, cough syrup, a solution of salt or sugar in water, etc. Heterogeneous solutions are solutions with non-uniform composition and properties throughout the solution. A solution of oil and water, water and chalk ...
Substances which have a specific composition and cannot be separated into any constituents are called pure substances. Pure substances are further divided into elements and compounds. The combination of two or more pure substances is called a mixture. Mixtures can be classified into two types viz. heterogeneous and homogeneous mixtures.
A solution contains two substances that are chemically mixed to form a new compound. The chemical properties of all substances are retained without change. Chemical properties usually change. The amount of substances in a mixture can vary and amounts don’t have a fixed ratio. A solution usually has a fixed ratio or amount of substances.
Part (b) A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. Example: Air, Sugar water, Rainwater. A heterogeneous mixture is a mixture, where the components of the mixture are not uniform or have localized regions with different properties.
