What metal Cannot be extracted using carbon? Carbon is a reducing agent at higher temperatures and from the electrochemical potential point of view or reactivity series carbon is present above many important metals e.g. zinc,iron,copper,silver,gold so it is used to reduce their oxides to extract metals from them but Carbon is present below Potassium so […]
What is the difference between weight mass and density?
What is the difference between weight mass and density? Density is used to measure the matter in a unit volume of an object whereas weight refers to the gravitational force applied of any object. The components of Density are mass and volume whereas, on the other hand, the components of weight are mass and gravity. […]
What is the relationship between kinetic energy on the state of the substance?
What is the relationship between kinetic energy on the state of the substance? As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of […]
Which channel is best for 2.4 GHz?
What element is a metal with 28 electrons?
What element is a metal with 28 electrons? NICKEL – I What is not alkali metal but is in Group 1? They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). (Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is […]
What is the best renewable energy?
What is the best renewable energy? The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy. What problems does renewable energy solve? Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some […]
How does Centre of gravity work?
How does Centre of gravity work? The center of gravity is the average location of the weight of an object. We can completely describe the motion of any object through space in terms of the translation of the center of gravity of the object from one place to another, and the rotation of the object […]
What are the causes of strain?
What are the 5 main electron group geometries?
What are the 5 main electron group geometries? Electron group geometries refer to the five geometries: linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral. If one or more of the bonding pairs of electrons is replaced with a lone pair, the electron geometry does not change but the the shape of the molecule is altered. […]
What type of risk factor is age?
What type of risk factor is age? Abstract. The risk of developing cardiovascular disease (CVD) is generally dependent on the presence or absence of traditional risk factors. Age is a well-known traditional risk factor, generally considered nonmodifiable. What are the two type of risk factors? Types of Risk Broadly speaking, there are two main categories […]
