Answer: 6.02214179×1023 atoms
Explanation: I think so
Answer: The correct answer is: " endothermic . "
______________________________________
<u>Note</u>: Heat flows <u> into </u> [heat <u> may be </u> absorbed within] an "<u>endothermic</u>" reaction or system
To the contrary, heat flows <u> </u><u>out </u> [heat <u> may </u><em> </em>exit from or <u> may be </u> released from] an "<u>exothermic</u>" reaction or process.
<u>Hint</u>: Think of the "prefixes" of: "<u>endo</u>thermic" and "<u>exo</u>thermic" :
_____________________________________
1) endo- = "within" (as in "endothermic" —heat tends to be absorbed/"within"/"released within"/released within"/into" ;
2) exo- = " outwards"/"exit" (as in "exothermic") —heat tends to '"exit"/leave/escape from/"be released out of/form".

According to Gases law, we know,
PV/T = Constant
So, P₁V₁/T₁ = P₂V₂/T₂
Here, P₁ = 108 kPa
V₁ = 592.2 mL
T₁ = 10+273 = 283 K
P₂ = ?
V₂ = 750 mL
T₂ = 28.9+273 = 301.9
Substitute their values,
108 * 592.2 / 283 = P₂ * 750 / 301.9
P₂ = 63957.6 * 301.9 / 283 * 750
P₂ = 19308799.44 / 212250
P₂ = 90.97 kPa
In short, Your Final Answer would be: 90.97 kPa
Hope this helps!
Answer:
The fraction of the available octahedral positions are filled with 
ions is 
Explanation:
If there are n numbers of spheres in HCP in packing:
Number of octahedral void = n
Number of tetrahedral void = 2n
Total number of voids = n + 2n = 3n
The 
crystal structure consists of an HCP arrangement of 
ions.
Number of spheres in HCP = 6
Number of = 6
Number of octahedral voids = 6
Number of tetrahedral void = 12
Number of aluminum ions when there are 6 ion =
Number of voids in which 
ions are present = 4
The fraction of the available octahedral positions are filled with ions = 
Warm is less heaver then cold air so warm air rise and cold air sinks
