Solid, ductile, and malleable. Ductile means it can conduct heat, and malleable means it can be shaped differently.
Here, we apply a mass balance:
Moles of chloride ions in final solution = sum of moles of chloride ions in added solutions
We must also not that each mole of sodium chloride will release one mole of chloride ions, while each mole of magnesium chloride will release two moles of chloride ions.
Moles = concentration * volume
Moles in final solution = moles in NaCl solution + moles in MgCl₂ solution
C * (150 + 250) = 1.5 * 150 + 2 * 0.75 * 250
C = 1.5 M
The final concentration is 1.5 M
C or D! When reduced coenzymes produce in the process of the cycle, are oxidized in the process of oxidative phosphorylation in electron transport chain! I hope this helps :(
In this problem, we can formulate two equations.
First, the overall mass balance of the ointment. The mass of
30% salicylic acid ointment plus the mass of petrolatum must be 50 grams.
x + p = 50
Where x is the mass of 30% salicylic acid ointment and p is
the mass of petrolatum
Second, the component mass balance of salicylic acid:
0.3 * x = 50 * 0.05
x = 8.33 g
Therefore the mass of petrolatum to be used is:
x + p = 50
p = 50 – x
p = 50 – 8.33
p = 41.67 g
Answer:
41.7
