Answer:
13.9atm
Explanation:
Use Boyle's Law: P1V1 = P2V2
Manipulate the equation: P2 = P1V1/V2
Substitute the values: P2 = (1.31atm)(5.51L)/0.520L
P2 = 13.88096atm
Optionally round to 3 sig figs to get 13.9atm
Explanation:
1. Electrons surround the nucleus in defined regions called orbits.
2. The shells further away from the nucleus are larger and can hold more electrons.
3. The shells closer to the nucleus are smaller and can hold less electrons.
4. The closest shell (closest to the nucleus) can hold a maximum of two electrons.
5. Once the first shell is full, the second shell begins to fill. It can hold a maximum of eight electrons.
6. Once the second shell is full, the third shell begins to fill.
7. Once the third shell contains Eighteen electrons, the fourth shell begins to fill.
8. The arrangement of electrons in shells around the nucleus is referred to as an atom's electronic configuration.
The substance (water) used to clean the beaker could effect the outcome of the experiment.
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.
A football field is 0.001 km in length. Since the 1 is in the thousands place, you’d have to run back and forth (0.001 km) 1000 times.
0.001 x 1000 = 1
