Does Coquina fizz in acid? Calcite is the main component of limestone rocks and its varieties like oolitic limestone, fossiliferous limestone, coquina and marble. The calcite mineral is made of calcium carbonate which reacts with acid. Other varieties of calcium carbonate minerals such as aragonite and dolomite will also fizz during this test. Is Coquina […]
What is the difference between boron and silicon?
What is the difference between boron and silicon? Boron is exclusively found in the mineral fraction of bone. Silicon is distributed equally in the mineral and collagen fractions. Data suggest boron and silicon have different biological effects on bone. Silicon loading into bone mineral may be influenced by nutritional factors. What is boron used for? […]
What is the melting point of water?
What is the melting point of water? 0 °C Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to […]

What would be the path of reflected light if an incident ray passes through focus?
What would be the path of reflected light if an incident ray passes through focus? An incident ray passing through the focus will be reflected parallel to the principal axis. Why the light ray retraces its path when it passes through Centre of curvature? Answer: The reason for light falling on the centre of curvature […]
What is the relationship between wavelength and speed?
What is the relationship between wavelength and speed? Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. What is the longest […]
