Answer:
p + is the basic notation
The pressure : 1.536 atm
<h3>Further explanation</h3>
Same container=same volume⇒the volume is constant
Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>
P₁=1 atm
T₁=20+273=293 K
T₂=450 K
the pressure :
Answer: Near the Protons. The electron structure of bromine is illustrated above. In chemical reactions, how does the valence configuration of Bromine tend to change? ... It loses one electron.
Explanation:
btw i found that on google lol
The products and reactants weigh the same since u have to balance out the equation to have an equal number of molecules on bothsides
<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
