Answer:
Molecular formula is C₂₆H₃₆O₄
Explanation:
The compound is 75.69 % C, 8.80 % H and 15.51 % O. This data means, that in 100 g of compound we have 75.69 g, 15.51 g and 8.80 g of, C, O and H, respectively. We know the molar mass of the compound, so we can work to solve the moles of each element.
In 100 g of compound we have 75.69 g C, 15.51 g O and 8.80 g H
In 412 g of compound we would have:
(412 . 75.69) / 100 = 311.8 of C
(412 . 15.51) / 100 = 63.9 g of O
(412 . 8.80) / 100 = 36.2 g of H
Now, we can determine the moles of each, that are contained in 1 mol of compound.
312 g / 12 g/mol 26 C
64 g / 16 g/mol = 4 O
36 g / 1 g/mol = 36 H
Molecular formula is C₂₆H₃₆O₄
Explanation:
precipitation like snow rain with increased acid is know as acid precipitation
A polyatomic molecules is a molecule that is composed of more than one element. The elements in this molecule are chemically bonded and has a net charge that is neutral like an ion. Example are CO2 and H2O. On the other hand, diatomic molecule is a molecule that is composed of two same atoms which are bonded covalently. An example is oxygen, it exist as O2.
Answer:
known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe.
Explanation:
Shielding alpha and beta particles is part of radiation safety, which is followed very seriously in nuclear power plants, hospitals, laboratories where particle accelerators are used, and in many more situations. Alpha particles are much easier to block than beta particles. Alpha particles are positively charged helium nuclei, and beta particles are negatively charged electrons. Finding materials to block alpha and beta particles requires some serious consideration because of how dangerous radiation exposure is. Density is very important when is comes to blocking these particles. The cool thing about alpha particles, though, is how easily they can be blocked. You would think that blocking a particle would take some seriously thick metal or something, but you could actually use paper, or even plastic to block these particles!
