Answer:
Equilibrium will lie to the right.
Explanation:
![K_{a}(HF)> K_{a}(C_{6}H_{5}COOH)](https://tex.z-dn.net/?f=K_%7Ba%7D%28HF%29%3E%20K_%7Ba%7D%28C_%7B6%7DH_%7B5%7DCOOH%29)
That means HF is stronger acid than
.
Alternatively, it can be said that
is a stronger base than
.
Therefore HF readily gives proton to
to form
and
than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of
and
.
Ek = (1/2)mv^2
m=7kg
v=4m/s
Ek=(1/2)(7kg)(4m^2/s^2) = 14 kg m^2/s^2
Question:
Assume you are working for a chemical company and are responsible for growing a yeast culture that produces ethanol. The yeasts are growing well on the maltose medium but are not producing alcohol. What is the most likely explanation?
a- the maltose is toxic
b- O₂ is in the medium
c- not enough protein is provided
d- the temperature is too low
e- the temperature is too high
Answer:
The correct option is;
b- O₂ is in the medium
Explanation:
The production of ethanol from glucose by the introduction of yeasts is known as fermentation process.
Yeast + Glucose → Ethanol +CO₂
The yeast ferments the glucose anaerobically to produce energy, CO₂ and ethanol
Therefore, ethanol production takes place in the absence of oxygen.
When oxygen is present, the yeast undergoes aerobic respiration, it breathes to produce energy by consuming the glucose and the oxygen. In the process, water and carbon dioxide are also produced.
Yeast + Glucose + Oxygen → H₂O + CO₂.
Answer:
Fractions. There are several ways of classifying the useful fractions that are distilled from crude oil. One general way is by dividing into three categories: light, middle, and heavy fractions. Heavier components condense at higher temperatures and are removed at the bottom of the column.
