marta [7]

Answer:

0.1

Explanation:

We must first put down the equation of the reaction in order to guide our solution of the question.

2HNO3(aq) + Sr(OH)2(aq) -------> Sr(NO3)2(aq) + 2H2O(l)

Now from the question, the following were given;

Concentration of acid CA= ??????

Concentration of base CB= 0.299M

Volume of acid VA= 17.8ml

Volume of base VB= 24.7ml

Number of moles of acid NA= 2

Number of moles of base NB= 1

From;

CAVA/CBVB= NA/NB

CAVANB= CBVBNA

CA= CBVBNA/VANB

SUBSTITUTING VALUES;

CA= 0.299 × 24.7 ×2 / 17.8×1

CA= 0.8298 M

But;

pH= -log[H^+]

[H^+] = 0.8298 M

pH= -log[0.8298 M]

pH= 0.1

A stover-to-ethanol plant produces 40,000 tonne/yr of ethanol and contains 8functionalunits:feedstockhandling,pretreatment,simul
Step2247 [10]

Answer:

FCI=458000*8*40000^{0.3}\\FCI=880818398.52 M

FCI=88.0818 MM≅88 MM

Explanation:

Empirical correlation based on the work of Bridgwater and Mumford (1979):

For Liquid or solid phase Plants:

FCI=458000*N*F^{0.3}                       F<60,000 tonne/yr     Eq (1)

FCI=7000*N*F^{0.68}                         F≥60,000 tonnes/yr   Eq (2)

Where:

N is the number of functional units

F is the process throughput tonnes/yr

In our case F=40,000 tonne/yr <60,000 tonne/yr, We are going to use Eq (1)

FCI=458000*N*F^{0.3}                       F<60,000 tonne/yr

N=8, F=40,000 tonne/yr

FCI=458000*8*40000^{0.3}\\FCI=880818398.52 M

FCI=88.0818 MM≅88 MM
