Hg2+ Refer(1) Why is detection of Hg2+ important?? Mercury contamination poses severe health risks. It can enter into environment through natural as well as human activities. Once it enters marine environment‚ bacteria convert inorganic mercury to methyl mercury which enters food chain and is accumulated in large edible fish. Its imbalance can lead to neurological disorders and can cause Minamata disease. Procedure to detect Hg2+ 1. MS1 (Mercury Sensor 1)‚ a water soluble‚ fluorescein based sensor

but back to learning about the universe. It is true that we only have 8 planets. However‚ the solar system is comprised of 100s of different miscellaneous worlds which are very adequate. Some of the moons and minor planets are more massive than Mercury. Some have active volcanoes and oceans of liquid methane which is quite hazardous and random. Almost every planet and some moons have an atmosphere. If we had lost our transparent atmosphere though some may

Mystery of the Cosmos. His book logically explained why the sun lies at the center of the solar system. He noticed that Mercury and Venus always seem to be close to the sun‚ unlike Mars‚ Jupiter and Saturn. This is because Mercury and Venus orbits are closer to the sun than Earth’s. Kepler said that if the sun and all the planets orbited Earth‚ there is no explanation as to why Mercury and Venus should always be near the sun. Including Earth‚ there were only six planets at the time. Kepler was able to

There are also vents‚ made when a magma chamber collapses. Mercury’s density has produced a solid iron core that accounts for 60% of its volume. As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many plains and craters. The largest crater on Mercury is the Caloris
