What do you call for subtracting the same number a number of times?
This action is called DIVISION. The opposite of this, continuous addition is MULTIPLICATION.
Where do you find remmington model 51 serial numbers?
65000 were made from 1917-1927 in 32ACP and 380ACP. http://unblinkingeye.com/Guns/Rem51/rem51.html
I've never heard of it but i have thought about it before. i mean it can be vaporized so im sure it can be condensed. the confusing part is that it is a solid. i came up with a design and that would be to hook up a THC vaporizer to a bottle filled with everclear. put the hose from the vaporizer in the bottle, so the vaporized THC would bubble up through it. you would have to make sure the alcohol is cold enough to condense it quickly. then evaporate the alcohol and you would have somewhat pure THC (i believe its a white powder when its pure.) using this method you can eliminate the other substances that are alcohol soluble but don't vaporize.
Who suggested that atoms are composed of the same substances all with different sizes and shapes?
Ancient Greek philosophers.
Is there a way to effectively determine the number of items in a container using mathematics?
Yes. If you have a square container and the volume is 27 inches. 3inches in length and 3 inches in height and 3 inches in width. Say have to fill it with 1 inch cubes. You would multiply 3x3x3 and get 27. That would be a good hypothesis.
Can elementary charge be changed?
Yes and no. Technically speaking the charge of a subatomic particle such as an electron or proton is always the same, this is why they are called constants. However, the methods that have been employed to determine the actual value of the elementary charge may not be the correct value. This would be due to experimental error, etc.

What is the nucleus's composition?
The atomic nucleus contain neutrons and protons; these particles are formed from quarks and gluons.
How many atoms are in 1.5 g C?
1.5g/12.0107g = n,
n * 6.022*10^23 = 7.520793959e22
In this case n would equal .124888641
12.0107 is the grams in one mole of Carbon (Found in the Periodic table -- Atomic Mass)
6.022*10^23 is avogadro's number or one mole.
What are element that differ in the number of neutrons known as?
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
There are 10 atoms in two nitric acid molecules. Namely they are two hydrogen atoms, two nitrogen atoms and six oxygen atoms.
What element has 8 protons 9 neutrons and 8 electrons?
Giving a specific number of protons and neutrons specifies an isotope of an element. In this case, the isotope is the isotope of fluorine with an atomic mass of 19. Other isotopes of fluorine with different numbers of neutrons also exist, but are not nearly as common.
To convert moles to atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Simply multiply the number of moles by Avogadro's number to get the number of atoms. For example, if you have 2 moles of a substance, you would have 2 x 6.022 x 10^23 atoms.
How any valence electrons does s 32 have?
The element sulfur (S), which has an atomic number of 16, has six valence electrons. In its electron configuration, sulfur has the configuration of 1s² 2s² 2p⁶ 3s² 3p⁴, with the valence electrons found in the outermost shell (the third shell). Therefore, sulfur, including its isotope with mass number 32 (sulfur-32), has the same number of valence electrons, which is six.
Can Neutrons carry a positive charge that is why the core of an atom is positively?
No, neutrons do not carry a positive charge; they are electrically neutral particles. The positive charge in the core of an atom, known as the nucleus, comes from protons, which have a positive charge. Neutrons, along with protons, make up the nucleus, but they do not contribute to its overall charge. Therefore, the nucleus is positively charged due to the presence of protons alone.
