Answer:
After measuring the solute, Carl should first dissolve the solid in a small amount of DI water before diluting to the total volume.
Explanation:
To ensure that all the solute dissolves in the solution, first dissolve the solid in less than the total volume of solution needed.
To determine the Keq, we need the chemical reaction in the system. In this case it would be:
CO + 2H2 = CH3OH
The Keq is the ration of the amount of the product and the reactant. We use the ICE table for this. We do as follows:
CO H2 CH3OH
I .42 .42 0
C -0.13 -2(0.13) 0.13
-----------------------------------------------
E = .29 0.16 0.13
Therefore,
Keq = [CH3OH] / [CO2] [H2]^2 = 0.13 / 0.29 (0.16^2)
Keq = 17.51
Answer: the way root cells reproduce to increase root length
Explanation:
Rudolf Ludwig Carl Virchowas known as the founder of social medicine and also the father of modern pathology.
Virchow posited that all cells are gotten from already existing cells and he used this in his work towards cellular pathology, as it was made clear that diseases takes place at the cellular level. He posited that the cells that are malfunctioning cause diseases.
Based on the above analysis, the image that Tumu would most likely use in his assignment to feature Rudolf Virchow is the way root cells reproduce to increase root length.
Answer:
V₂ = 4.82 L
Explanation:
Given data:
Initial volume of gas = 3.5 L
Initial pressure = 115 Kpa
Final volume = ?
Final Pressure = 625 torr
Solution:
Final Pressure = 625 torr (625/760 =0.82 atm)
Initial pressure = 115 Kpa (115/101 = 1.13 atm)
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.13 atm × 3.5 L = 0.82 atm × V₂
V₂ = 3.955 atm. L/0.82 atm
V₂ = 4.82 L
