What is H3PO4 balanced? H3PO4 = H2O + H4P2O7. Instructions and examples below may help to solve this problem. You can always ask for help in the forum. Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click ‘Balance’. What type of reaction is Koh H3PO4? Type of Chemical Reaction: For […]

When did China Land on the Moon? 14 December 2013 Is Chang E on the moon? Landing site The Lander/Ascender landed on the Moon on 1 December 2020 at 15:11 UTC. The Chang’e 5 landing site is at 43.1°N (in latitude), 51.8°W (in longitude) in the Northern Oceanus Procellarum near a huge volcanic complex, Mons […]

What is the weight of a person whose mass is 60 kg? Weight = Fg = mg = (60 kg)*(9.8 m/s2) = 588 N. Is density different from weight? The difference between Density and Weight is that density is used to measure the amount of matter contained in a unit volume. On the other hand, […]

At what position is the kinetic energy of the skater the highest? At the top of the ramp, before he starts moving downward, the skateboarder has zero KE, due entirely to the fact that he is not moving. At the bottom of the ramp, the skateboarder has maximum KE because he is moving at the […]

What is an imaging technique? Diagnostic imaging techniques help narrow the causes of an injury or illness and ensure that the diagnosis is accurate. These techniques include x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI). What is 3D imaging used for? 3D imaging is a technique to develop or create the illusion of […]

What is the first sign of the ecliptic? Earth’s precessional wobbling causes the vernal equinox point to migrate around the ecliptic once every 26,000 years. This point was once in Aries the Ram, hence the term “First Point of Aries.” The vernal equinox point is now in Pisces and in the late 26th century will […]

Are chills a sign of anxiety? Cold sensations and chills are actually a common physical symptom of anxiety. Yet another interesting physical effect of anxiety is its ability to alter how our body temperature feels. Why do I get random chills when Im not cold? Chills are a common symptom of infections like pneumonia, urinary […]

What is the wavelength of cosmic waves? Energy distribution From that work, and from many other experiments carried out all over the world, the energy spectrum of the primary cosmic rays is now known to extend beyond 1020 eV. What is the frequency we use for satellite communication and why? x Band Satellite Communication operates […]

What will happen if Earth goes into a black hole? If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. Eventually, some time later, any object at rest — no matter how far away from the event horizon it initially was — will […]

Why are dark and bright fringes formed in ripple tank? They are caused by the variation in height and angle of the surface of the water. When light rays pass through, they scatter in slightly different directions. The result is a web of lines where more of the light is focused. What would happen if […]
