Do you need a soil boring to test your soils before building a house foundation?
Yes, the related cost to getting a soil boring test is pretty minimal compared to the possible problems that could arise during construction and compared to the overall construction costs of your house/building.
How did the properties of the sulfur alone compared with the sulfur in the unheated iron sulfur combination?
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
Is nuclear energy renewable or non-renewable?
Nuclear energy is nonrenewable, as it depends on limited supplies of the fissionable isotope Uranium-235. Uranium is dug out of the ground. Some day there will be none left. Fissionable fuels (and other elements that can be used in reactors to make them) are "stellar fossil fuels" made more than 6 billion years ago by exploding supernovas and when they run out like the chemical fossil fuels made millions of years ago will be all gone and will never replenish while the human species exists.The supplies of fissionable isotopes can be extended (but not renewed) by breeding more in reactors. It involves making plutonium from non-fissile uranium in breeder reactors: Uranium-233 from Thorium-232 and Plutonium-239 from Uranium-238. This will extend the amount of reactor fuels by roughly a factor of 100, but beyond that no more fissionable isotopes can be produced. When we run out we run out. Also, plutonium is a key ingredient for nuclear bombs. While this is a known way to produce a longer lived supply of nuclear energy, the dangers of making this fuel are such that the international community frowns strongly upon the use of breeder reactors because of their proliferation issues. Bernard Cohen argues that breeder reactors, using fuel dissolved in the oceans, can supply all of Earth's energy needs for billions of years, even after the sun explodes, which should categorize them as "renewable".Traditional nuclear fission power plants use only a tiny fraction of the uranium in the fuel rods before actinides build up, poisoning the reaction. However, the nuclear fuel rods can be reprocessed into new fuel rods. The actinide components each have various uses in industry and for medical purposes. In some types of reactors called "breeder reactors", casing of thorium or depleted uranium is built around the nuclear reactor, causing the thorium or depleted uranium to capture a neutron and become uranium or plutonium respectively. When reprocessed, the uranium or plutonium can be extracted and used to power additional reactors.The US does not use breeder reactors. France has some, but the majority of nuclear reactors in the world are not of this type. So in that sense we're back to non-renewable.If we someday make workable fusion reactors, we will have an effectively unlimited supply of nuclear energy, because there is far more hydrogen available to use as fuel than there is uranium and thorium. However this is still nonrenewable as the amount of hydrogen on earth will not increase significantly (tiny amounts arrive on meteorites).A good source for information about energy the International Energy Agency. They define renewable energy as being derived from natural processes that are replenished constantly. However both fission and fusion will be able to supply our energy needs for SO long it's crazy.
What is an elliptical moon?
An elleptical moon is when the moon is in shadow during a lunar ecclipse, this causes a masive shadow on one point on the earth though it is very small compared to the earth, before the moon covers the sun, there is a part of the sun still vissible and it looks like the moon just before the new moon, the sun is very bright then and it is therefore called the diamond ring effect.
Why is a oxide ion larger than a oxygen atom?
In an oxide ion, electrons get added. This means, lesser nuclear charge. This is due to screening effect. The inner electrons shield the outer electron from the nuclear charge which is why the outer electrons get relatively lesser nuclear charge. So, more electrons means lesser nuclear charge. Consider a person standing in front of you. You get blocked from the view in front of you. Suppose two more people stand in front of you. Now, it is more difficult for you to catch a glimpse of the front view than it was before. This is exactly what happens in the oxide ion. Lesser nuclear charge means the electrons do not get pulled towards the nucleus as they were before, i.e., in the oxide ion, the electrons do not get pulled towards the nucleus as they were in the neutral oxygen atom.So, the electrons will be farther than they originally were.Thus, an oxide ion is larger than an oxygen atom.
What element comes before uranium and after on table?
Before uranium is protactinium. After uranium is neptunium.
What was used before uranium?
Before uranium discovery and before the 150 years long study of its properties the nuclear energy was nonexistent.
What does before nucleus mean?
Prokaryotic cells don't have a defined nucleus.
What isotope of uranium has less than 3 neutrons?
None, no element beyond lithium can have a stable isotope with as few as 3 neutrons. If by some happenstance a uranium nucleus did form with as few as 3 neutrons (this would be U95) it would instantly burst apart in a flash of protons before it could even be detected.
Is uranium dangerous before it is processed?
Processed or not uranium has some disadvantages: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and radioactive chemical element. 3. Uranium release radium and radon.
What Before nucleus?
Prokaryotic cells don't have a defined nucleus.
What are cells called when they dont have a nucleus?
Prokaryote. Means; " before the kernel. " Which is literal Greek for before the nucleus.
Why is a chain reaction more likely in a big pieces of uranium than its in a small piece?
A small piece has more surface area compared to its mass; as a result, more neutrons will escape before they can participate in the chain reaction.
What kind of cell that does not have a nucleus?
A prokaryote is a cell without a nucleus. The prefix Pro- means before, in this case, before the nucleus developed. A cell with a nucleus is a eukaryote.
What origin does the name uranium come from?
Uranium name is derived from the name of the planet Uranus. Uranus was discovered a few years before the discovery of Klaproth in 1789 - a mineral containing uranium.
What was uranium used for before 1920?
For colouring glasses and ceramics.
Do prokaryotes have nucleus?
no thats what prokaryotes means - "before nucleus"
