Explanation:
Molar mass of
is 94 g/mol. As it is known that number of moles is equal to mass of a substance divided by its molar mass.
Then, calculate the number of moles as follows.
No. of moles =
in 1 s
= 0.914 mol
So, in 60 sec number of moles will be equal to 0.914 x 60 = 54.89 mol/min.
Hence, the molar flow rate = 54.89 mol/min
Also, density is equal to mass of a substance divided by its volume.
Density = ![\frac{mass}{volume}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D)
Volume = ![\frac{mass}{Density}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7BDensity%7D)
= ![\frac{86.0 g}{1.0625 g/cm^{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B86.0%20g%7D%7B1.0625%20g%2Fcm%5E%7B3%7D%7D)
= 80.941 ![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
As, 80.941
of volume flows in 1 s
. Therefore, flow of volume in 1 hour will be calculated as follows.
In 1 hr = 80.941
= 291388.24 ![cm^{3}/hr](https://tex.z-dn.net/?f=cm%5E%7B3%7D%2Fhr)
Since, 1
= 0.001 L.
So, 291388.24 ![cm^{3}/hr \times 0.001 L/cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D%2Fhr%20%5Ctimes%200.001%20L%2Fcm%5E%7B3%7D)
= 291.38824 L/hr
Thus, we can conclude that molar flow rate in mol/min is 54.89 mol/min and the volumetric flow rate in L/hr is 291.38824 L/hr.
The answer is b. 4.2 mole. The balanced reaction formula is 2LiOH + H2SO4 -->Li2SO4 + 2H2O. And the ratio of mole number of the reactants is the same as the ratio of coefficients.
Answer:
The answer to your question is A and B
Explanation:
Chemical reactions can be classified by the energy that they need to proceed or the energy they release.
Endothermic reactions are reactions that require energy to proceed most of the time this energy is in the form of heat.
Exothermic reactions are reactions that release energy to proceed, this energy could be in the form of heat or light.
Answer:
Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.
Explanation:
Answer:
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.
