What is the atomic mass listed in the periodic table?
The atomic mass listed on the periodic table is typically called atomic weight, and is the weighted average of the masses of all the naturally occurring isotopes of a chemical element. The term atomic weight is now controversial, and may be phased out in the future. Atomic weight is still in use partially to prevent confusion concerning the atomic masses of individual isotopes.
Why do elements have a listed average atomic mass and not just atomic mass?
Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
How do the greenhouse gases affect the ozone layer?
Ozone is itself a greenhouse gas.Water vapor is a greenhouse gas, and it serves to deplete ozone (water vapor blocks one path of ozone production, and provides an additonal decay path).Carbon dioxide is a greenhouse gas that has no effect on ozone.Any gas with three or more atoms per molecule is a greenhouse gas (like CFCs). For the most part, any of these gases in the atmosphere (with the exception of those listed above) are in too small a quantity to have any significant effect on global temperatures, whatever effect they may eventually have on ozone.Another answerThe burning of fossil fuels, which are ancient plants and animals, compressed and heated, is a large contributor to the greenhouse gases. There is a lot of carbon in the fossil fuels, and when they are burned, the carbon is released. The carbon then creates carbon dioxide, which is what creates a lot of greenhouse gases. The greenhouse gases warm our planet, altering ecosystems and life. They also can cause depletion of the ozone layer.
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
How does the relative abundance of each hydrogen isotope affects hydrogen average atomic mass?
The atomic masses shown on the Periodic Table and listed in chemistry textbooks are "weighted" averages of all the naturally occurring isotopes for the particular element in question. The higher the abundance of a particular isotope, the more that isotope contributes to the overall weighted average - that is, to the Atomic Mass on the Periodic Table. Since hydrogen's atomic mass is 1.00 794 atomic mass units, it is clear that the Hydrogen-1 isotope is the most abundant of the three naturally occurring isotopes of hydrogen: protium, deuterium, and tritium. Protium makes up far more than 99% of any naturally occurring sample of hydrogen with deuterium (1 proton and 1 neutron) making up almost all of the rest. Tritium (1 proton and 2 neutrons) is typically present only in trace amounts. To determine the average atomic mass, the masses of the individual isotopes and their relative abundances are measured using a mass spectrometer. Then the fractional abundance is multiplied by the measured isotopic mass for each isotope and the products of these multiplications are then added together to give the recorded atomic mass on the Periodic Table.
What are the 4 naturally occurring forces in the universe?
gravityelectromagneticweakstrongThat is listed by order of range.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.

What 6 sources of greenhouse gas in the US including the percentage?
H2O (Water vapor) ~5% --- accounts for about 72% of the greenhouse effect CO2 (Carbon Dioxide) ~0.038 % --- accounts for about 15% of the greenhouse effect CH4 (methane) ~0.00175 --- accounts for about 7% of the greenhouse O3 (Ozone) --- accounts for about 5% of the greenhouse effect The rest of the gases listed below make up pretty much all the rest of the greenhouse effect: N2O (nitrous oxide) ~0.00031 --- HFCs (hydrofluorocarbons) PFCs (perfluorocarbons) SF6 (sulphur hexafluoride)
If a food contains Vitamin K is it required that the vitamin's presence be listed on the label?
Only if it is added. If it is present naturally it is not listed.

Does batiste test on animals?
No, Batiste does not test on animals according to various cosmetic sources. They are listed as a cruelty-free brand on those sources.

Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
How much fruit juice per 1 pouch of certo?
Depends on the fruit. Different fruits have different amounts of naturally occurring pectin. Strawberry jam can be made without pectin altogether, for instance, where pear is pretty tricky. The box comes with an insert listed many common options. What fruit do you want to use?
