Find three other chemicals that can be produced from fermentation besides ethanol.

List some other substrates that could be used to replace glucose, especially if they would typically be a byproduct of another process.

why yeast might produce ethanol during fermentation if ethanol is eventually toxic to them.

The phosphate in a 4.258-g sample of plant food was precipitated as
Ag3PO4
through the addition of 50.00 mL of 0.0820 mol L-1 AgNO3
:
3Ag+ + HPO42- ⇌ Ag3PO4(s) + H+
The solid was filtered and washed, following which the filtrate and
washings were diluted to exactly 250.0 mL. Titration of a 50.00-mL
aliquot of this solution required a 4.64-mL back-titration with 0.0625
mol L-1 KSCN. Express the results of this analysis in terms of the
percentage of P2O5
.

How many milliliters of water have to be added to 300 mL of stock solution of 11.1 M HNO3 to have final concentration of 6.00 M?

which element does not form a stabel ion with the same electronic structure as argon?
A aluminium
B chlorine
C phosphorus
D potassium

1) Find three other chemicals that can be produced from fermentation besides
ethanol. Do these fermentations use yeast or some other organism? What are
the substrates and the products?

2)In this fermentation, glucose is used as the substrate. As a pure sugar, however,
it is rather expensive. List some other substrates that could be used, especially if
they would typically be a byproduct of another process.

3) why yeast might produce ethanol during fermentation if ethanol is
eventually toxic to them.

1.what are three ways that yeast use carbon(in the form of glucose)? Try to make some generalizations about what microorganisms need (chemically), keeping in mind that there are organisms that can fulfill their “building block” and energy needs using things like carbon dioxide, carbon monoxide, sulfur, and ammonia.

Looking at your patterns, how could you predict the bonding pattern of elements based on their location in the periodic table. You might consider the following: chemical families, valence electrons, electronegativity, ionization energy, and oxidation numbers (charge). For element CS2

ICP-MS was used for the determination of the arsenic content in fern given
above. ICP-AES (Atomic Emission Spectroscopy) could also have been
employed. Explain the measurement principle and describe the processes
a sample undergoes from its introduction into an ICP to the detection and
quantification of elements using EITHER MS OR AES.
