Answer: -

Water can dissolve other substances. Which factor best contributes to this property of water?

d. Water particles are not fixed in place.

Explanation: -

When a substance like say common salt sodium chloride NaCl is dissolved in water, the water molecules surround the Na⁺ and Cl⁻ which result from dissolving of NaCl in water.

The water molecules by surrounding the Na⁺ and Cl⁻ help in dissolving NaCl.

Thus in order to surround them,the water molecules should not be fixed in their place and be free to move about.

The kb for methylamine (ch3nh2) at 25 ∘c is 4.4×10−4. what is the value of δg at equilibrium?
Oliga [24]
Answer is: <span> </span>ΔG for <span>methylamine is 18.85 kJ/mol.
</span>ΔG = R·T·lnK.
ΔG is Gibbs energy.
<span>T is the temperature on the Kelvin scale.
R is </span><span>ideal gas constant.
R = 8.314 J/mol</span>·K.
T = 25°C = 293.15 K.
Kb = 0.00044.
ΔG = - 8.314 J/mol·K · 293.15 K · ln(0.00044).
ΔG = 18836.85 J = 18.84 kJ.

Which of the following is NOT a possible end-product of a fermentation process?- glucose- carbon dioxide- lactic acid- ethanol
MArishka [77]

Answer:

glucose

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration:

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration:

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.  

Steps involve in anaerobic respiration are:

Glycolysis:

Glycolysis is the first step of both aerobic and anaerobic respiration. It involve the breakdown of one glucose molecule into pyruvate and 2ATP.

Fermentation:

The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced in this step, however carbon dioxide is released.
