What are the property of ionic compound? Ionic compounds have high melting points. Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. Which of the following is a property of salts? When this solid […]

Do doorbells have batteries? Most wired doorbells will use a doorbell transformer to power the system. There are battery powered wired doorbells that will use batteries, thus bypassing the need for a transformer, but these systems have some limitations. How does a battery operated doorbell work? The button is battery-powered and the system is wireless. […]

What is gas chromatography used for in real life? Gas Chromatography is used in airports to detect bombs and is used is forensics in many different ways. It is used to analyze fibers on a persons body and also analyze blood found at a crime scene. In gas chromatography helium is used to move a […]

Which forms of nuclear radiation are capable of ionizing matter? Ionizing radiation takes a few forms: Alpha, beta, and neutron particles, and gamma and X-rays. All types are caused by unstable atoms, which have either an excess of energy or mass (or both). What is the meaning of ionizing radiation? Listen to pronunciation. (I-uh-NY-zing RAY-dee-AY-shun) […]

Is the stationary phase polar or nonpolar? Stationary phases are usually very polar, while mobile phases vary widely in polarity, but are less polar than the stationary phase. This is called normal phase (NP) chromatography. The exception is reverse phase (RP) chromatography, in which a polar mobile phase, and a less polar stationary phase are […]

Are the cells produced by mitosis the same or different than the original mother cell? Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell. What […]

What would produce an average velocity of zero? The average velocity of a body becomes zero when its displacement is zero. Because according to the formula: velocity = displacement/time. Is acceleration the magnitude of average velocity? Acceleration is the rate at which velocity changes. Acceleration is a vector; it has both a magnitude and direction. […]

Is Alpha Beta or Gamma more penetrating? Beta radiation is more penetrating than alpha radiation. It can pass through the skin, but it is absorbed by a few centimetres of body tissue or a few millimetres of aluminium. Gamma radiation is the most penetrating of the three radiations. Why is beta radiation more penetrating than […]
