<u>Answer:</u> The original element is 
<u>Explanation:</u>
Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units.
The released alpha particle is also known as helium nucleus.
For the given alpha decay process of an isotope:
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
A = 208 + 4
A = 212
<u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
Z = 82 + 2
Z = 84
The isotopic symbol of unknown element is
Hence, the original element is
Answer:
The correct answer is "more fluid bilayers".
Explanation:
A fatty acid is a biomolecule of lipidic nature formed by a long hydrocarbon chain of different lengths at the end of which there is a carboxyl group.
The wall of the gallbladder consists of three main layers of tissue: The mucosa covers the wall of the gallbladder. The muscular layer of smooth muscle. The serosa, which is the outer layer.
By decreasing the saturation of the fatty acid chains in phospholipids, the bile layers would reduce their thickness and become more fluid.
Have a nice day!

Answer:
Yes<em>!</em>
Explanation:
<u>Liquids</u> & <u>gases</u> are poor conductors, but they can make heat (thermal energy) travel quickly from one point to another. ... ~ When waves of heat (thermal energy) travel through empty space and transparent mediums, heat transfer by radiation occurs. <u>Solids, liquids,</u> & <u>gases</u> can all be heated by radiation.

Answer:
3.0 moles Al₂O₃
Explanation:
We do not know which of the reactants is the limiting reactant. Therefore, you need to convert both of the given mole values into the product. This can be done using the mole-to-mole ratio made up of the balanced equation coefficients.
4 Al + 3 O₂ -----> 2 Al₂O₃
6.0 moles Al 2 moles Al₂O₃
---------------------- x ------------------------- = 3.0 moles Al₂O₃
4 moles Al
4.0 moles O₂ 2 moles Al₂O₃
---------------------- x ------------------------- = 2.7 moles Al₂O₃
3 moles O₂
As you can see, O₂ produces the smaller amount of product. This means O₂ is the limiting reactant. Remember, the limiting reactant is the reactant which runs out before the other reactant(s) are completely reacted. As such, the actual amount of Al₂O₃ produced is 2.7 moles.
However, since this problem is directly addressing how much Al₂O₃ is produced from Al, the answer you most likely are looking for is 3.0 moles Al₂O₃.
