Answer:
1.70 mol of ethanol is needed
Explanation:
First, we have to write the balanced equation for reaction of ethanol with oxygen to produce acetic acid and water
Balanced reaction:
According to balanced equation, 1 mol of ethanol produces 1 mol of
So, moles of ethanol needed to produce 1.70 mol of water = 1.70 mol
Answer:

Explanation:
Answer:
1. Digestive system.
2. Respiratory system
3. Nervous system
4. Immune system
Explanation:
When you go to the doctor for an illness, the doctor asks you how you feel. You describe all your symptoms. Then, the doctor makes hypotheses about which organ system is having problems.
1. Digestive system: stomach ache, gassy, no appetite.
2. Respiratory system: sneezing all the time, runny nose, trouble breathing, coughing.
3. Nervous system: having a very hard time remembering people's names, feeling sad and anxious.
4. Immune system: seem to be catching every disease that comes around, taking a long time to get a better
The volume is increased to 4.52 L on decreasing the pressure to 93.3 kPa.
Explanation:
As per Boyle's law, the volume occupied by gas particles will be inversely proportional to the pressure experienced by those particles at constant temperature.
So in the present problem, the volume of gas at pressure P₁ = 99.6 kPa is given as V₁ = 4.23 L. The temperature is kept constant at 24°C. Then, if the pressure is decreased to 93.3 kPa, then the volume is tend to increase due to Boyle's law.
So let us consider the new pressure be P₂ = 93.3 kPa and the new volume has to be found.
Then using Boyle's law,
Then,
So,
Thus, the volume is increased to 4.52 L on decreasing the pressure to 93.3 kPa.
The answer to number 11 is 76.04 g!! I have attached a picture showing you my work. You want to go from mass to moles, so i first wrote down the info that we know- 2.00 mol. I then determined the mass of H2O2 in one mol
I did this by looking at the periodic table and looking at the atomic mass (bottom number) for each element and it’s quantity.
I then multiplied 2.00 by 38.03 because the bottom number on the fence post (1 mol) cancels out! I hope this helps you!
