We could use the Boyle's law for gases.
This law states that:
Which means that at a constant temperature, as pressure increases, volume decreases. (P1 and V1 are the initial pressure and volume and P2 and V2 are the final pressure and volume respectively)
We could replace the values of the problem to get:
Now, replacing in the equation:
Therefore, the new pressure will be 148.44psi.
Answer: D) All of the above
Explanation:
The sources of errors in the kinetic experiment are depends upon the tools, due to some personal errors and also due to some methodological problem. As, experimental error during kinetic study is due to the difficulty to characterize the experimental errors depend on reaction conditions. The behavior of the experimental errors are depend on specific feature of the experiment systems.
Answer:
Molar mass of vitamin K = 450.56\frac{g}{mol}[/tex]
Explanation:
The freezing point of camphor = 178.4 ⁰C
the Kf of camphor = 37.7°C/m
where : m = molality
the relation between freezing point depression and molality is
Depression in freezing point = Kf X molality
Where
Kf = cryoscopic constant of camphor
molality = moles of solute dissolved per kg of solvent.
putting values
2.69°C = 37.7°C/m X molality
molality = 0.0714 mol /kg
moles of vitamin K = 0.0714X0.025 = 0.00178 mol
we know that moles are related to mass and molar mass of a substance as:
For vitamin K the mass is given = 0.802 grams
therefore molar mass = 
Analogous structures are those structures in different species which perform the same function, have similar appearance and structure but are not evolved together; therefore do not share a common ancestor. Homologous and analogous organs video explains in a simple way.
Statement 1 is false because heat is the movement of molecules.
Statement 2 is true because matter is composed of elementary particles which are VERY small.
Statement 3 is false because the kinetic energy of a particle determines its heat and it is impossible for a particle to be completely motionless.
Statement 4 is false because neutrons do not have a charge and make up a large portion of all matter.
