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? […]

How did Newton figure out gravity?
How did Newton figure out gravity? The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest. Did Newton really discover […]

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 […]
What is the most common way for a virus to kill a cell?
What is the most common way for a virus to kill a cell? Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell’s surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell. […]
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 […]
