Answer:
The answer to your question is below
Explanation:
Alpha decay occurs when a radioactive atm emits an alpha particle (Helium atom).
a) ²⁵⁶Ra ⇒ ²⁵²₈₄ Po + ⁴₂He
b) ²¹⁹Rn ⇒ ²¹⁵₈₂Pb + ⁴₂He
c) ²¹¹Po ⇒ ²⁰⁷₈₀Hg + ⁴₂Hg
d) ²¹⁰Pb ⇒ ²⁰⁶₇₈Pt + ⁴₂Hg
e) ²³⁸U ⇒ ²³⁴₈₈U + ⁴₂Hg
Answer:
Both electrons of Mg should be transferred to one O.
Explanation:
This is because metals like to lose electrons whereas non metals like to gain electrons in an ionic compound. MgO is an ionic compounds. So Magnesium being a metal in group 2 of periodic table, it wants to donate 2 electrons to get to the octet rule, so it donates its electrons and oxygen accepts them to fill its octet rule.
The iodine with greatest electrons will be sulfur
Answer:The number of moles will remain the same in the two cases
so we can equate using ideal gas equation which is PV =nRT
V2 = 3100 L
