Is gold a solute? Not all solutions are liquids. Solutions can also be solids. In a solid solution, both the solvent and the solute are solids. In this case, gold is the solvent and the other metals are the solutes. Why is gold a homogeneous mixture? Because the material is uniform throughout, it is homogeneous. […]
What is science and example?
What is science and example? Science is the study of the nature and behaviour of natural things and the knowledge that we obtain about them. A science is a particular branch of science such as physics, chemistry, or biology. Physics is the best example of a science which has developed strong, abstract theories. What is […]
How do you write 21000 in scientific notation?
How do you write 21000 in scientific notation? Why is 21,000 written as 2.1 x 104 in scientific notation? How do you write 0.000345 in scientific notation? Convert from Real Number to Scientific Notation: 0.000345 = 3.45 x 10. Here we wish to write the number 0.000345 as a base times 10 raised to an […]
What is the device that melts if it gets too hot?
What is the device that melts if it gets too hot? An electrical fuse is a device that sacrifices itself to provide over-current protection in an electrical circuit. If too much current flows, the fuse wire rises to a higher temperature and melts, thus opening the circuit, but destroying the fuse. Does heat bend metal […]
How close should you stay to your dive flag padi?
What is the oxidation number for lead?
What is a Type 3 curve?
What is a Type 3 curve? The Type III curve, characteristic of small mammals, fishes, and invertebrates, is the opposite: it describes organisms with a high death rate (or low survivorship rate) immediately following birth. In contrast, the Type II curve considers birds, mice, and other organisms characterized by a relatively constant… What animals have […]
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle?
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle? Solution. If we stop pedalling a bicycle, moving at a uniform speed, it does not go on moving forever. It eventually comes to rest after some time. This is […]
What is the level of intensity of your physical activity in general?
What is the level of intensity of your physical activity in general? Typically, the intensity of physical activity can be described as light, moderate or vigorous. To benefit health, Australia’s Physical Activity and Sedentary Behaviour Guidelines recommend a variety of moderate and vigorous intensity physical activity. What is RPE level? Perceived Exertion (Borg Rating of […]
What is the half life of a first-order reaction if time required to decrease?
What is the half life of a first-order reaction if time required to decrease? Concentration is reduced to 25%. It means it takes two half-lives to decrease the concentration of reactant from 0.8 M to 0.2 M in first-order reaction. Hence, half-life of the reaction is 12/2 = 6 hours. The half life of reaction […]
