Read the article by Michael Fumento, writer for the New York Post editorial blog, who does not support global warming.
Back in 2005 I and others reviewed the entire hurricane record, which goes back over a century, and found no increase of any kind. Yes, we sometimes get bad storms—but no frequently now than in the past. The advocates simply ignored that evidence.
Fact is, the earth was cooling and warming long before greenhouse gases could have been a factor. The [global warming supporters] have been proved wrong time and time again.

An ion has 56 protons, 54 electrons, and 81 neutrons. What is its atomic #?
Answer:
110.91982
The element is probably Barium
The atomic number of an atom is equal to the number of protons it has. In this case, the ion has 56 protons. Therefore, the atomic number of the ion is 56.
The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei composed of protons and neutrons, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. In an ordinary uncharged atom, the atomic number is also equal to the number of electrons.
For an ordinary atom which contains protons, neutrons and electrons, the sum of the atomic number Z and the neutron number N gives the atom's atomic mass number A. As there are 56 protons thus the atomic number of the ion is 56.

in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?
Explanation:
When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.

Use metric and U.S. conversion factors to solve the problem.
Question - If a student is 175 cm tall, how tall is the student in meters?
Explanation:
100cm = 1m
1cm=1/100 m
175cm = 175/100 m = 1.75m.
hope this helps you.
If a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.
What is a Metric system?A metric system may be defined as a type of system that significantly weighs and measures the mass and distance respectively in which the meter is the unit of length and the kilogram is the unit of weight.
A metric system is a standard system of measurement which utilizes the meter, liter, and gram as base units of length for distance, capacity for volume, weight for mass, etc.
According to the question, the height of a student in cm = 175 cm.
Then, from the general conversion rule,
1 meter = 100 cm.
1 cm = 1/100 meter.
175 cm. = 175/100 = 1.75 meters.
Therefore, if a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.

Concerning chromatography, why do different colors in the ink separate?
A)Some colors had a greater repulsion for the paper or water. The colors that had a greater repulsion for the paper moved faster, and those with a greater repulsion for the water moved slowly up the paper.
B)Some colors had a greater affinity for the paper or water. The colors that had a greater affinity for the water moved faster, and those with a greater affinity for the paper moved slowly up the paper.
C)Some colors had a greater repulsion for the paper or water. The colors that had a greater repulsion for the water moved faster, and those with a greater repulsion for the paper moved slowly up the paper.
D)Some colors had a greater repulsion for the paper or air. The colors that had a greater affinity for the air moved faster, and those with a greater affinity for the paper moved slowly up the paper.
E)Some colors had a greater affinity for the paper or water. The colors that had a greater affinity for the paper moved faster, and those with a greater affinity for the water moved slowly.
Substances that have greater affinity for the solvent travel faster while the substance that have greater affinity for the paper travel more slowly.
Chromatography involves a mobile phase and a stationary phase. The mobile phase is the solvent that carries the mixture. while the stationary phase is the medium that performs the actual separation
The speed with which components of the ink moves up the paper depends on its affinity for the paper or the water.
The different colors in the ink separate because some colors had a greater affinity for the paper or water. The colors that had a greater affinity for the water moved faster, and those with a greater affinity for the paper moved slowly up the paper.

What is the weighted average of lemonas if 80% are the GX model (4,000 lbs) and 20% are
the GXL model (5,000 lbs)?
Answer:
4200
Explanation:
4,000 * .8 + 5,000 * .2
The weighted average of lemonas with 80% GX model and 20 % GXL model is calculated using their mass percent and it is 4200.
What is weighted average?
The weighted average is different from the normal average we use in maths. Let's X and Y be two number and their average be x+ y/2. That is the arithmetic mean.
The weighted average of lemonas is similar to the atomic weight of an element calculated from ist two isotopes where, the percentage abundance in earth and the mass of isotopes if given the weighted average is calculated as follows:
weighted average = % abundance / 100 × mass of isotope 1 + % abundance / 100 × mass of isotope 2
In a similar way, the weighted average of lemonas of GX and GXL model is calculated as follows:
weighted average = ( 4000 lbs ×80/100 ) + ( 5000 lbs ×20/100)
= 4200 lbs.
Hence, the weighted average of lemonas if 80% are the GX model (4,000 lbs) and 20% are the GXL model is 4200 lbs.

Isotope 2 amu: 186.956
percent abundance: 62.6%
Atomic Mass of the element ?
Answer: Not possible to find average amu with only the information provided.
Explanation:
Is there more information about the other isotopes? I don't see how one could calculate an overall atomic mass with only one isotope is known. An isotope of 186.956 with abundance of 62.6% isn't enough information. We're not told anything about the other isotopes: are they larger, smaller, and at what percentage. If one has an amu of 204.956 at 37.4%, the overall atomic mass would be quite different than if it had an atomic mass of 182.956 at 37.4%. More infornmation is required.
