Is calcium carbonate a ionic compound?
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).

What will happen when a ringing tuning fork is lowered into water?
What will happen when a ringing tuning fork is lowered into water? When struck, the double-pronged metal rod vibrates at a constant frequency — and thus emits a constant pitch. The naked eye can’t spot the vibrations, but dipping the tuning fork in water and slowing down the footage make them anything but invisible. What […]
