Answer:
The temperature is 69.05 K.
Explanation:
We have,
Number of moles are 6
Pressure is 3.4 atm and a volume of 10 liters.
It is required to find the temperature. It can be calculated using gas law equation. It says that,
P is pressure
V is volume
n is number of moles
R is gas constant, 
T is temperature
Plugging all the values we get :
So, the temperature is 69.05 K.
Answer:
b. glass and charcoal
Explanation:
Step 1: Given data
- Density of Glass: 2.6 g/mL
- Density of charcoal: 0.57 g/mL
- Density of platinum: 21.4 g/mL
Step 2: Determine which material will float in molten lead
Density is an intrinsic property of matter. Less dense materials float in more dense materials. The materials whose density is lower than that of lead and will therefore float on it are glass and charcoal.
Describe how the catalyst, zymase speeds up the
reaction shown
The catalyst zymase speeds up the
reaction by catalyzing the fermentation of sugar into ethanol and carbon
dioxide. It is mostly present in yeasts.
