Answer:
The molecular formula of an ascenapthalene is 
Explanation:
where,
=Elevation in boiling point = 
Mass of acenapthalene = 0.515 g
Mass of 
= 15.0 g = 0.015 kg (1 kg = 1000 g)
= boiling point constant = 3.63 °C/m
m = molality
Now put all the given values in this formula, we get
Let the molecule formula of the Acenapthalene be ![C_{6n]H_{5n}](https://tex.z-dn.net/?f=C_%7B6n%5DH_%7B5n%7D)
n = 2.0
The molecular formula of an ascenapthalene is
Answer: X: High and Y: High
Explanation: When comparing plasma with solids it is seen that solids are more denser than plasma and has less kinetic energy as compared to plasma.
So among the difference plasma will have high kinetic energy and solids will have high density in comparison with each other.
I think it’s called condensation or water vapor
Answer:
The answer to your question is U-234
Explanation:
Data
Thorium-234
beta emission twice
Definition
Beta emission is when a beta particle (electron) is emitted from an atomic nucleus.
First beta emission
²³⁴₉₀Th ⇒ ²³⁴₉₁Pa + e⁻
Second beta emission
²³⁴₉₁ Pa ⇒ ²³⁴₉₂U + e⁻
The atom will be Uranium-324
Answer:
Explanation:
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.Ionic charges are not yet supported and will be ignored.Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.Compound states [like (s) (aq) or (g)] are not required.You can use parenthesis () or brackets [].
