Is calcium carbonate a ionic compound? Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above). Why calcium carbonate has both ionic and covalent bond? Calcium carbonate is another example of a […]
Can concave lens produce real image?
Can concave lens produce real image? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object. What are the properties of lenses? […]

When both quantitative and qualitative methods are beneficial?
When both quantitative and qualitative methods are beneficial? A combination of qualitative and quantitative research is typically best for most design projects if budget allows. By using both methods you can achieve a deeper level of insight through the exploratory nature of the research in addition to statistical evidence to support your design decisions. What […]
What are the examples of physical geography?
What are the examples of physical geography? Physical geography also includes the processes, such as erosion, landslides, earthquakes, and volcanoes, that shape and change the landforms around us. Other elements of physical geography include rock types and minerals, a field known as geology. What are the main elements of physical geography? (b). Elements of Geography […]
Is continental or oceanic plates heavier?
Is continental or oceanic plates heavier? Because of their heavy ferromagnesian elements, oceanic plates are much denser than continental plates. The average density of ocean plates is approximately 200 pounds per cubic foot, while continental crust ranges between about 162 and and 172 pounds per cubic foot. What are 3 differences between oceanic and continental […]
What liquid is hardest to freeze?
What liquid is hardest to freeze? Liquid helium What affects the boiling point? The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. Is it true that water boils at higher […]

Do I have to memorize kinematic equations for MCAT?
Do I have to memorize kinematic equations for MCAT? Kinematic equations are the foundation to mastering MCAT physics. Yes you have to ‘memorize’ and know the standard formulas, but it goes deeper than that. You have to understand the units, when to use which equation, and be VERY comfortable applying these concepts to the more […]
