Answer:
B) System.
Explanation:
It is a group of parts working together. They work together to make a whole, therefore they are all a system when working together.
Answer:
The partial pressure of argon in the flask = 71.326 K pa
Explanation:
Volume off the flask = 0.001 
Mass of the gas = 1.15 gm = 0.00115 kg
Temperature = 25 ° c = 298 K
Gas constant for Argon R = 208.13 
From ideal gas equation P V = m RT
⇒ P = 
Put all the values in above formula we get
⇒ P =
× 208.13 × 298
⇒ P = 71.326 K pa
Therefore, the partial pressure of argon in the flask = 71.326 K pa
Answer:
20atm
Explanation:
according to boyles law P1V1= P2V2
FeCl₂ + 2NH₄OH → Fe(OH)₂ + 2NH₄Cl
