There is differ motion you go through the day translational, rotational, periodic, and non periodic motion.
Hope this helped you
Sorry if it wrong
The actual size of something times the magnification is equal to the size of the appearance of the object in the image. Therefore, to find the magnification, divide the size of the image by the actual size of the object.
The mass of stars affect how they end.
Stars with greater mass sometimes end with supernovas, a giant explosion, which can result in black holes or neutron stars, or sometimes nothing.
A medium sized star can result in a planetary nebula, which then results in a white dwarf.
Haha hope this sorta helped :)
Answer:
Empirical SiCl3
Molecular Si2Cl6
Explanation:
Since it contains 79.1% chlorine, this means it contains (100 - 79.1)% silicon = 20.9% chlorine
To get the empirical formula, we firstly need to know the atomic masses of both chlorine and silicon. This is 35.5 and 28
We then divide the percentage abundances by the corresponding atomic masses.
Cl = 79.1/35.5 = 2.23
Si = 20.9/28 = 0.75
We then divide by the smallest, which is 0.75
Cl = 2.23/0.75 = 3
Si = 0.75/0.75 = 1
The empirical formula is thus SiCl3
To get the molecular formula:
(28+3(35.5))n = 269
134.5n = 269
n = 269/134.5 = 2
The molecular formula is Si2Cl6
Answer:
The reason carbon-13 is more abundant than carbon-14 despite them both being isotopes is because carbon-13 is stable and doesn't decay into other elements, unlike carbon 14.
Explanation:
Carbon isotopes come in three forms. By far the most common isotope of carbon is carbon-12 (12C), which contains six neutrons in addition to its six protons. The next heaviest carbon isotope, carbon-13 (13C), has seven neutrons. Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 (14C) isotope contains eight neutrons in its nucleus. Unlike 12C and 13C, this isotope is unstable, or radioactive. Over time, a 14C atom will decay into a stable product.
