what is the appearance of the mixture
In a homogeneous mixture, the composition remains uniform throughout the mixture, meaning all samples taken from different parts will have the same composition. In a heterogeneous mixture, the composition can vary throughout the mixture, leading to different samples having different compositions.
If the probability that an individual sample is negative is ( p ), then the probability that all 6 samples are negative (and thus the mixture tests negative) is ( p^6 ). Conversely, the probability that at least one sample is positive (and thus the mixture tests positive) is ( 1 - p^6 ). Therefore, the outcome of the mixture test depends significantly on the value of ( p ).
A mixture in which samples are not necessarily made up of exactly the same proportions of matter is called a heterogeneous mixture. This type of mixture is not uniform throughout and may contain visible differences in composition. Examples include salad with different types of vegetables or a jar of mixed nuts with varying amounts of each nut.
A mixture in which all samples are made up of the same proportions of matter is called a homogeneous mixture. In such mixtures, the components are evenly distributed, and they cannot be easily distinguished from one another. Examples include solutions like saltwater or air.
A heterogeneous mixture has two or more distinct phases with different characteristics. Because of this, two random samples of a heterogeneous mixture may have different compositions. For example, the phases in mud are the water and soil particles, which remain distinct from one another. These phases are not necessarily visible, but may exist as microscopic clusters or particles. By contrast in a homogeneous mixture any two random samples will be identical.
Raw egg is a hetrogenous mixture, you can see this when you crack an egg, it clearly has 2 componants and you will not observe the same uniform composition if you take several random samples.
No, you do not need to know the individual masses of the samples of water and salt to measure the change in mass when they are mixed. You can simply measure the mass of the mixture before and after mixing to determine the change in mass.
A homogenous mixture (or substance or solution) is one where in every part of the mixture (or etc.), the proportion of each component of it is the same. For example, if you took samples of a homogenous mixture from the top, middle and bottom of the tank, they would all be 60% A, 30% B and 10% C.
No, a typical soil sample is not an example of a homogeneous mixture. Soil is composed of various components such as minerals, organic matter, water, and air that are not uniformly distributed throughout the sample, making it a heterogeneous mixture.
Water samples containing dissolved substances are known as solutions. The substances are dissolved in the water, resulting in a homogeneous mixture where the particles are evenly distributed.
After staining, the samples will appear as distinct bands or spots on the gel, with each band representing a different fragment of DNA, RNA, or protein. The intensity of the bands will depend on the amount of each sample present in the original mixture.
