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:
Molecular- compound B, Ionic - compound A
Explanation:
Molecular compounds are compounds containing two or more non-metal for example carbon dioxide and covalent in nature. They usually have low melting and boiling points and will vaporized faster. Compound A on the other hand is ionic; they usually have high melting and boiling points and when dissolved in water they dissociate into ions ( actions and anions)
Answer:
11
Explanation:
Moles of KOH =
Volume of water = 10 liters
Concentration of KOH is given by
is strong base so we have the following relation
So, pH of the solution is 11
It even and equally distributes the heat, therefore giving the food a more thorough cook in the microwave compared to one without a turntable.
