Answer:
coloumbs
Explanation:
the value of the charge on a proton is Coloumbs
Answer: The mole fraction of neon in the final mixture is 0.6
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 5.0 atm
= partial pressure of argon = 2.0 atm
= partial pressure of Neon = ? atm
According to Raoults law, the partial pressure of a gas is equal to its mole fraction mulitiplied by the total pressure.
= mole fraction of Neon
Thus mole fraction of neon in the final mixture is 0.6
Answer:
hypothesis
Explanation:
it would be an explanation made on the basis of evidence
Answer:
An endothermic reaction
Explanation:
A positive sign indicates that energy is absorbed. Hence it is an endothermic reaction.
A reversible reaction is indicated by a double arrow on the chemical equation.
A spontaneous is indicated by negative Gibbs Free Energy (G) value.
An exothermic reaction is indicated by a negative enthalpy change
Answer:
The appropriate solution is:
(a) n ≈ 900
(b) n ≈ 1165
Explanation:
According to the question,
(a)
The final number of molecules throughout water will be:
=
where, n = number of extractions
Now,
The initial number of molecules will be:
=
=
Final number of molecule,
⇒
(b)
Final molecules of X = left (0.01%)
hence,
⇒
