Why can some mixtures be separated by chromatography? Chromatography can be used to separate mixtures of coloured compounds . As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out. How many main ways are there to separate […]

Bike Riding Technique. Increase Length Rides. Train On Hills. Interval Training Sessions. Previous Alimentation. During Cycling Alimentation. Be Consistent. […]
Do elements in Group 1 gain or lose electrons?
Do elements in Group 1 gain or lose electrons? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions. Most elements in […]
What is Charles Law in simple terms?
What is Charles Law in simple terms? Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the […]
What do theories and laws have in common?
What do theories and laws have in common? As previously stated, a scientific theory is a well-substantiated explanation of some aspect of the natural world. A scientific law is simply an observation of the phenomenon that the theory attempts to explain. The theory of gravity is the explanation as to why the apple falls to […]
What is the effect of pollution on human life How is pollution controlled?
What is the effect of pollution on human life How is pollution controlled? Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer’s and Parkinson’s diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight. What is an […]
Is atomic nucleus positive or negative?
Is atomic nucleus positive or negative? The nucleus (plural, nuclei) is a positively charged region at the center of the atom. It consists of two types of subatomic particles packed tightly together. The particles are protons, which have a positive electric charge, and neutrons, which are neutral in electric charge. Can nucleus be positive? The […]
What is the relationship between air pressure and weather?
What is the relationship between air pressure and weather? Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. How pressure affects the wind flow? Air Pressure and Winds Air that moves horizontally between […]
Can a vector has infinite components?
Can a vector has infinite components? A vector can be split into infinite components (but only 3 orthogonal ones) Are vectors one dimensional? Yes. Not only are one dimensional vectors a thing, “zero dimensional” vectors are too! An example of a one dimensional vector would just be any real number, as you observed. How do […]
What elements have the smallest atomic radius?
What elements have the smallest atomic radius? Explanation: Helium has the smallest atomic radius. Which element has the largest atomic radius K or Na? As an example, potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, […]
