We are using the General gas equation P x V/K = P x V/K
1. P = 1atm V=500ml so PxV= 500 at 6.5km P = 0.5atm V = ? so P xV = 0.5 x V
(We don't have to worry about temperature!) 500 = 0.5 x V so V = 1000ml
2. NO CHANGE in pressure here so we have V/K V=2.75 K = 20 + 273=293 so V/K= 2.75/293
Next set V = 2.46 K = ? so V/K = 2.46/K then 2.75/293= 2.46/K so K=(293/2.75)x2.46
=262 K
Convert back to Celsius 262 - 273 = -11 C
It's raining so I have to rescue the laundry!
Laundry rescued!
3.Now we have to use all three variables. I am using 273K and 100kPa for STP.
P = 100 V = 700 K = 273 These are altered P - unknown, V = 200 K = 273+30=303
!00 x 700/273 = 256.4 this is equal to P x 200/303 = P x 0.66
so P = 256.4/0.66 = 388.48kPa
I believe the strength comes from its ability to break the particle bond in the molecule. So the bond dissociation energy
Based on the properties of minerals, the following are true:
- Fluorite can de distinguished from quartz based on Color and Hardness.
- Solubility is not a property of minerals.
<h3>Properties of minerals</h3>
- Hardness - minerals can be differentiated based their resistance to be scratched.
- Cleavage - the way minerals break up.
- Color - minerals has different colors but this is not often a reliable property.
Flourite and Quartz have different colors and hardness with Quartz being harder than flourite.
In conclusion, solubility is not a mineral property.

Answer:
DONT PRESS THAT THAT IS HACK AND VIRUS
Explanation:
The given units are the units of masses which are interconvertable.
It is given that:
Now, converting :
Since,
So,
Now converting :
Since, 1 kg = 1000 g
So,
For :
Thus, of ointment needed to be prepared by the pharmacist.
