Al, since it is the only metal in that list
Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.

Answer : The molality of sodium chloride is, 1.79 m
Explanation :
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute (sodium chloride) = 49 g
= Molar mass of solute (sodium chloride) = 58.5 g/mol
= Mass of solvent (water) = 469 g
Now put all the given values in above equation, we get:
Hence, the molality of sodium chloride is, 1.79 m
Answer:
I think
Explanation:
Li = 2s^1
Be = 2s^2
B = 2p^1
C = 2p^2
I think that is what it is asking if not sorry
Molecular weight of air = 29 g/mole, moles of air entering = 5/29 kgmoles/hr= 0.1724 kg moles/hr
Moles of N2= 0.21*0.1724=0.036 kg moles/hr, moles of N2= 0.79*0.1724= 0.1362 kgmoles/hr
Moles of CO2 can be calculated from gas law equation, n= PV/RT
V= 25 m3/hr= 25* 1000 L/hr, P= 2 bar = 2*0.9869 atm,=1.9738 atm R= 0.0821 L.atm/mole.K T= 100 deg.c =100+?273.15= 373.15K
n= number of moles of CO2= 1.9738*25*1000/ (0.0821*373.15) =1611 moles/hr= 1.611 kg moles/hr
total moles of mixture = 0.1724 +1.611 =1.7834 kg moles/hr
Moles % CO2 in the mixed stram = 100*1.611/1.7834 = 90.33%
Answer is 90.33%
