Which elements is most likely to be shiny? That is, calcium is likely to be shiny….Metals display lustrous properties than non metals. Sulphur is a non metal. Boron is also a non metal. Calcium is a metal. Carbon is a non metal. Which element is most likely to bend without breaking? Cobalt What element has […]

Why is iron the heaviest element that can be produced in stars? After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of […]

Is Bread harmful to cats? Cats can safely eat bread on occasion, but note that bread contains no nutritional value for them (it has virtually no fat or protein), so it should not replace their normal cat food diet. Why is my cat obsessed with butter? Cats love foods that are high in fat, which […]

What are two main types of energy? After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. What form of energy is most important? The second law of thermodynamics: Using energy always makes it […]

What is an example of estate tax? Calculating estate tax: an example Let’s say that a single individual dies in 2020. At the time of their death, this person had assets with a total value of $15 million. Applying the 40% estate tax rate results in an estate tax due of $1,488,000. Who pays the […]

Are radiowaves harmful? Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage. Is UV light bad for your skin? Exposure to […]

Is Quadrant 3 positive or negative? In Quadrant I, both the x– and y-coordinates are positive; in Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative. Why is tan positive quadrant 3? for angles with their […]

What is the average rate of a reaction? The average rate of reaction is an average rate, obtained by taking the change in concentration over a time period. The rate at which chemical substances react varies greatly. Usually, a reaction rate involves the change in the concentration of a substance over a given period of […]

Which two factors can contribute to enzyme catalysis? Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. What is enzyme catalysis examples? Enzymes are biological catalysts. Enzymes are also proteins that are folded into complex shapes that allow smaller […]

Which axis of an ellipse is always shorter? Every ellipse has two axes of symmetry. The longer axis is called the major axis, and the shorter axis is called the minor axis. Each endpoint of the major axis is the vertex of the ellipse (plural: vertices), and each endpoint of the minor axis is a […]
